By arranging at least one set of protrusions 3 in parallel with each other, when forming the colored layer 12, the colored layer 12 is easily formed on the protrusions 3, while between the pair of protrusions 3. The colored layer 12 is hardly formed. For this reason, the contrast of the light transmittance or the light reflectance between the part having the protrusions 3 and the part between the pair of protrusions 3 becomes clear, and alignment can be facilitated. Further, when at least one set of protrusions 3 are arranged in parallel to each other, the depth of the plate forming the colored layer is increased, so that the space between the set of protrusions 3 is as shown in FIGS. Even if the colored layer 12 is formed in the peripheral portion of the protruding portion 3 excluding the portion, the colored layer 12 is difficult to be formed between the pair of protruding portions 3, so that the alignment is possible. That is, when at least one set of the protrusions 3 are arranged in parallel with each other, it is preferable in that the alignment can be performed even if the accuracy of pattern printing for alignment is slightly reduced. In addition, when at least one pair of protrusions 3 are arranged in parallel to each other, it is preferable in that the contrast for alignment can be easily clarified even if the height of the protrusions 3 is low. Furthermore, by arranging at least one pair of projecting portions 3 in parallel with each other, the contrast of light transmittance or light reflectance can be formed linearly, and the alignment accuracy can be improved, and the above-described blocking is suppressed. To improve the effect.

From the viewpoint of easily obtaining the above-described effects, the interval (P ₁ ) between the ends of the pair of protrusions 3 is preferably 0.1 to 10.0 mm, and 1.0 to 7.0 mm. More preferably, the thickness is 1.5 to 5.0 mm.

It is more preferable to satisfy the relationship, and it is further preferable to satisfy the relationship of 0.3 to 1.0.
By setting the ratio to be 0.1 or more, it is possible to easily suppress blocking when winding a long transfer sheet or stacking single transfer sheets, and the ratio is set to 5.0 or less. As a result, the protruding portion is not easily deformed by the load, and the alignment accuracy can be easily maintained.

It is preferable to remove the second region when it is transferred to the transfer object and a decorative molded product is obtained. The timing for removing the second region is, for example, (1) when the transfer sheet is slit long, (2) when the transfer sheet is cut into sheets, and (3) the transfer sheet is transferred. And the like during the trimming process after the transfer.

(Colored layer)
The colored layer is formed on the protruding portion and has a role of causing a light transmittance or a light reflectance contrast with the peripheral portion. Note that the “colored layer” in this specification includes a layer that looks whitish due to light diffusion (for example, a layer that looks like frosted glass).

The colored layer is preferably mainly composed of a binder resin and a pigment and / or a matting agent.
As the pigment of the colored layer, it is preferable to include a pigment having high concealability or a pigment having high reflectance. A black pigment such as carbon black is preferable as the pigment having high concealability. Examples of the pigment having high reflectance include barium sulfate, titanium oxide, and pearl pigment.
The matting agent for the colored layer can be used without any particular limitation as long as it provides irregularities on the surface of the colored layer and causes external haze. Specifically, examples of the matting agent include inorganic particles such as silica and alumina, and organic particles such as acrylic particles and styrene particles.
The binder resin of the colored layer is not particularly limited, and a general-purpose thermoplastic resin, a cured product of a thermosetting resin composition, or a cured product of an ionizing radiation curable resin composition can be used.

The thickness of the colored layer may be adjusted within a range where contrast for alignment is obtained, and is usually about 0.3 to 5.0 μm.

(Other areas)
The surface of the release sheet on the transfer layer side may have other regions other than the first region and the second region. By having other regions, the alignment accuracy can be further improved, and the design of the transfer object can be further improved.

For example, as shown in FIGS. 5 and 7, in the case where the protruding portion 3 of the second region R ₂ extends continuously in the flow direction, the position in the direction orthogonal to the flow direction is higher than the configuration of the second region R _2. Alignment is possible, but alignment in the flow direction is not possible. In such a case, by forming a position detector in the other region R _n, it is possible to further improve the accuracy of the alignment.

Position detection unit, for example, as shown in FIGS. 3 and 6, the second protrusion 6 formed in the other region R _n of the base layer 11, formed on the protruding portion 6 of the second The structure which consists of the made 2nd colored layer 14 is mentioned.

Second protrusion 6 may be formed on at least a portion of the other region R _n.
The second protrusion 6 preferably has a straight line parallel to the width direction of the transfer sheet when observed from the plane direction, and has a substantially rectangular shape having a straight line parallel to the width direction of the transfer sheet. Is more preferable, and a substantially rectangular shape having straight lines parallel to the width direction and the flow direction of the transfer sheet is more preferable. By making the 2nd protrusion part 6 into such a shape, it can be made easy to align with a flow direction.

When the second protrusion 6 has a straight line parallel to the width direction and / or the flow direction, the length of the straight line is preferably 2 to 20 mm, more preferably 3 to 15 mm. More preferably, it is 10 mm.

The height of the second protrusion 6 is preferably 1 to 10 μm, more preferably 2 to 7 μm, and even more preferably 3 to 6 μm. The height of the second protrusion 6 is preferably the same as the height of the protrusion 3 in the second region.
By setting the height of the second protrusion 6 to 1 μm or more, a colored layer is formed on the second protrusion 6 even if the printing position is slightly shifted, The second colored layer 14 can be hardly formed. That is, by setting the height of the second protrusion 6 to 1 μm or more, the alignment pattern can be easily printed at an accurate location. For this reason, the contrast of the light transmittance or the light reflectance between the portion having the second projecting portion 6 and its peripheral portion becomes clear, and the alignment can be facilitated. In addition, by setting the height of the protruding portion 3 to 1 μm or more, as shown in FIG. It is easy to suppress blocking when taking or stacking a single transfer sheet.
Further, by setting the height of the protruding portion 3 to 10 μm or less, the protruding portion is hardly deformed by a load, and the alignment accuracy can be easily maintained.

When the position is detected by the difference in light transmittance, the difference in light transmittance between the portion having the second protrusion 6 and the surrounding portion is preferably 30% or more. Moreover, when detecting a position by the difference in light reflectance, it is preferable that the difference in light reflectance between the location having the second protrusion 6 and the surrounding location is 30% or more.

When the degree of unevenness of the second uneven portion 7 is reduced, the second colored layer 14 is easily formed not only on the second uneven portion 7 but also around the second uneven portion 7. And as shown in FIG. 4, the thickness of the 2nd colored layer 14 formed on the 2nd uneven | corrugated | grooved part 7 becomes thin, while the location corresponding to a recessed part is thick, the location corresponding to a convex part becomes thin. . On the other hand, the thickness of the second colored layer 14 formed around the second uneven portion 7 is thick overall. For this reason, a contrast of light transmittance or light reflectance occurs between the second uneven portion 7 and the periphery of the second uneven portion 7 due to the difference in the adhesion density of the second colored layer 14. The position can be detected.

Further, when the degree of unevenness of the second uneven portion 7 is increased, the second colored layer 14 is easily formed on the protruded portion of the second uneven portion 7, while the recessed portion of the second uneven portion 7 is formed. In addition, it is possible to make it difficult for the second colored layer 14 to be formed around the second uneven portion 7. For this reason, the contrast of the light transmittance or the light reflectance is caused due to the difference in the adhesion density of the second colored layer 14 between the portion having the second uneven portion 7 and the peripheral portion, Detection can be possible.

The second concave-convex part 7 may be formed on at least a portion of the other region R _n.
Further, the second concavo-convex portion 7 preferably has a straight line parallel to the width direction of the transfer sheet when observed from the plane direction, and has a substantially rectangular shape having a straight line parallel to the width direction of the transfer sheet. Is more preferable, and it is more preferable that the transfer sheet has a substantially rectangular shape having straight lines parallel to the width direction and the flow direction of the transfer sheet.

The second colored layer 14 is preferably mainly composed of a binder resin and a pigment and / or a matting agent.
The embodiment of the binder resin, pigment, and matting agent of the second colored layer 14 is the same as the embodiment of the binder resin, pigment, and matting agent of the colored layer 12 formed on the protruding portion.
The thickness of the second colored layer 14 may be adjusted within a range in which a contrast for alignment is obtained, and is usually about 0.3 to 5.0 μm.

When forming a position detecting means described above to other areas R _n, as shown in FIGS. 3, 4 and 6, is with other regions R _n, the first region R ₁ and the second region R _2, It is preferable that the release sheet 10 is formed at different places in the width direction. With this positional relationship, positioning in the flow direction when forming the second colored layer 14 becomes unnecessary (the second colored layer 14 can be continuously formed in the flow direction), and workability can be improved.

When the position detection means described above is formed in other areas, it is preferable to remove the other areas when they are transferred to the transfer object and a decorative molded product is obtained. Examples of the timing for removing the other regions include (1) the process of slitting the transfer sheet into a long length, (2) the process of punching the transfer sheet into a sheet, and (3) the transfer sheet to be transferred. And the like during the trimming process after the transfer.

Although not shown, a shape different from the shape of the first region may be formed in other regions. For example, (a) when the first region has a concavo-convex shape, make the shape of the other region substantially smooth, and (b) when the first region has a concavo-convex shape, change the shape of the other region to the first region. It is conceivable that the concavo-convex shape is different from the concavo-convex shape, and (c) when the shape of the first region is substantially smooth, the shape of the other region is the concavo-convex shape.
By forming a shape different from the shape of the first region in other regions, the surface shape of the transfer layer transferred to the transfer object can be changed depending on the location. For this reason, the obtained decorative molded product has different glossiness depending on the place, and can improve the design.

In the case where the first region has an uneven portion, the uneven portion and the later-described protrusion and the peripheral protrusion satisfy the relationship of [maximum height of the uneven portion <the height of the protrusion and the peripheral protrusion]. preferable. By satisfying this relationship, it is possible to easily form the colored layer in preference to the top of the protruding portion and the peripheral protruding portion, and it is possible to suppress the formation of the colored layer in the first region, and to perform alignment. Can be done accurately.
From the same viewpoint, [the maximum height of the concavo-convex portion / the height of the protruding portion and the peripheral protruding portion] is preferably 0.50 or less, and more preferably 0.40 or less. Further, from the same viewpoint, the [average roughness of the uneven portion / height of the protruding portion and the peripheral protruding portion] is preferably 0.20 or less, and more preferably 0.15 or less.
When there are a plurality of protrusions, it is preferable that all the protrusions satisfy the above relationship. Moreover, it is preferable that all of the plurality of peripheral protrusions satisfy the above relationship.

Although not shown, the first region may be divided into two or more locations. In this case, the surface shape of each first region may be different. The design of the decorative molded product can be improved by dividing the first region into two or more locations and making the surface shape of each first region different.

(Second area)
As shown in FIG. 10 to FIG. 12, the release sheet 10 is located in the second regions R ₂ , R _2A , R _2B of the base material layer 11 in the vicinity of the

colored layers

12, 12 A, 12 B are formed on the protrusions and the peripheral protrusions. have.

As shown in FIGS. 12 to 16, the second regions R ₂ , R _2A , R _2B and the first region R ₁ described above are preferably formed at different locations in the width direction. By arranging the second region and the first region as described above, it is difficult to form the colored layer in the first region while forming the colored layer on the protruding portion and the peripheral protruding portion of the second region. it can. When forming the colored layer, it is preferable to use a printing plate that does not have ink in a portion corresponding to the first region and has ink in the entire surface corresponding to the second region.
13 to 16 illustrate a state where the surface of the release sheet is visible through the transfer layer.
In the second embodiment of the present specification, the “second region” means a region formed by the following four straight lines (1) to (4).
(1) A straight line drawn in parallel to the flow direction from a position located at the leftmost end of the peripheral protrusion when the transfer sheet is observed from the planar direction. (2) A straight line drawn parallel to the flow direction from the position located at the rightmost end of the peripheral protrusion when the transfer sheet is observed from the plane direction. (3) A straight line drawn in parallel to the width direction from the position located at the uppermost end of the peripheral protrusion when the transfer sheet is observed from the plane direction. (4) A straight line drawn in parallel to the width direction from the position located at the lowest end of the peripheral protrusion when the transfer sheet is observed from the plane direction.
In the second embodiment of the present specification, the “peripheral region in the second region” means a region obtained by removing the protruding portion from the second region.
In the second embodiment of the present specification, the width direction means the TD direction (Transverse Direction) of the transfer sheet, and the flow direction means the MD direction (Machine Direction) of the transfer sheet. Means.

A colored layer is formed on substantially the entire surface on the protruding portion of the second region. On the other hand, the peripheral region located around the protrusion has a protrusion (peripheral protrusion), and a colored layer is formed on the peripheral protrusion, but the peripheral protrusion is partially disposed in the peripheral region. Remains. Therefore, when the protrusion part of a 2nd area | region and a peripheral area | region are compared, the area ratio in which the colored layer is formed will differ. In other words, the light transmittance or light reflectance is different between the protruding portion of the second region and the peripheral region, and the position of the transfer sheet can be determined in an arbitrary process using the contrast of the light transmittance or light reflectance. Matching is possible. The light transmittance may be any of transmittance in the normal transmission direction, diffuse transmittance, and total transmittance. Similarly, the light reflectance may be any of transmittance in the regular reflection direction, diffuse reflectance, and total reflectance.
The ratio of the area of the peripheral protrusions to the total area of the peripheral region is preferably 15 to 85%, more preferably 20 to 80%, and further preferably 30 to 70%. By setting the ratio of the area of the peripheral protrusions to 15% or more, it is possible to suppress the formation of a colored layer in the peripheral area where the peripheral protrusions are not formed, and to improve the contrast of light transmittance or light reflectance. It is easy to clarify. Further, by setting the area ratio of the peripheral protrusions to 85% or less, the light transmittance or the contrast of the light reflectance can be easily clarified, and the alignment accuracy can be improved.
Examples of the optional step of aligning include a step of slitting the transfer sheet in a long length, a step of punching the transfer sheet into a sheet, and a step of transferring the transfer sheet to a transfer object. A specific method of alignment will be described later.

Distance _{P 1} of the ends of the peripheral projecting portion adjacent the second region is preferably 2.0mm or less, more preferably 1.0mm or less, still more preferably 0.7mm or less .
By the distance P ₁ and 2.0mm or less, to prevent the colored layer at a position near the projecting portion of the peripheral region is not formed is formed, it is possible to increase the accuracy of the alignment.
Incidentally, if the interval P ₁ is too narrow, it can adversely affect alignment. For example, when the light source used for alignment is not parallel light, or even if the light source is parallel light, alignment is performed based on the contrast of light transmittance when the emission surface of the light source is not horizontal. If it is going to be, light will become difficult to permeate | transmit the location where the peripheral protrusion part of a peripheral region is not formed, and there exists a possibility that the contrast of a protrusion part and a peripheral region cannot fully be performed.
Further, when the interval P ₁ is too narrow, it is not to narrow the width W ₂ of the peripheral projecting portion difficult to secure the contrast between the projecting portion and the peripheral region, can cause a problem due to narrowing the W ₂ to be described later is there.
Therefore, the end interval _{P 1} between the peripheral projecting portion is preferably at 0.01mm or more, more preferably 0.05mm or more, more preferably at least 0.10 mm.

A protrusion interval P ₂ between the peripheral projecting portion proximate the protruding portion, from the viewpoint of suppressing the colored layer on the interval is formed, preferably at 2.0mm or less, at 1.0mm or less More preferably, it is 0.7 mm or less.
But not limited interval lower limit of P ₂ is particularly, as shown in FIG. 13, the straight line constituting the outer shape of the protruding portion 3, when the peripheral projecting portion 4 are arranged in parallel, the protruding portions 3 and peripheral homogeneously forming a boundary line between the region X, for clear distinction between the projecting portion 3 and the peripheral region X, the interval _{P 2} is preferably 0.01mm or more, 0.05 mm or more It is more preferable that it is 0.10 mm or more.
In the second embodiment of the present specification, the “outer edge shape of the protruding portion” means a shape formed from the outer edge of the protruding portion when the protruding portion is observed from the planar direction.

When the position is detected based on the difference in light transmittance, the difference in light transmittance between the protruding portion of the second region and the peripheral region of the second region is preferably 30% or more. Moreover, when detecting a position by the difference in light reflectance, it is preferable that the difference in light reflectance between the portion having the protrusion and the surrounding portion is 30% or more.

The protruding portion and the peripheral protruding portion are formed from an arbitrary structure, and the shape and the like of the structure are not particularly limited, but the shapes exemplified below are preferable.

The height (H) of the protrusion and the peripheral protrusion is preferably 1 to 10 μm, more preferably 2 to 7 μm, and further preferably 3 to 6 μm.
Even if the printing position is slightly shifted by setting the height of the protruding portion and the peripheral protruding portion to 1 μm or more, a colored layer is formed on the protruding portion and the peripheral protruding portion. A colored layer can be made difficult to form. That is, by setting the heights of the protrusions and the peripheral protrusions to 1 μm or more, the alignment pattern can be easily printed at an accurate location, and the alignment accuracy can be increased. Further, by setting the height of the protruding portion 3 and the peripheral protruding portion 4 to 1 μm or more, as shown in FIGS. 10 to 12, a fine protrusion is easily formed on the surface of the transfer sheet 100 on the transfer layer 20 side. When the long transfer sheet is wound up or the transfer sheets are stacked, the blocking of the first region can be easily suppressed.
In addition, by setting the height of the protruding portion and the peripheral protruding portion to 10 μm or less, the protruding portion is hardly deformed by a load, and the alignment accuracy can be easily maintained.
The heights of the protrusions and the peripheral protrusions need not all be the same. For example, the height of the protruding portion and the height of the peripheral protruding portion may be changed, or the height of each peripheral protruding portion may be changed. However, from the viewpoint of facilitating uniform formation of the colored layer, it is preferable that the heights of the protrusions and the peripheral protrusions are all the same.
In the second embodiment of the present specification, the height (H) of the projecting portion and the peripheral projecting portion refers to the structure forming the projecting portion and the peripheral projecting portion in the extending direction of the structure (for example, In the case of the peripheral protrusions in FIGS. 13 to 15, it means the height of the central part of the cross section cut in a direction orthogonal to the direction “d”. When it cannot be determined that the film extends in any direction because the length in the width direction and the flow direction are the same, such as the protrusion 3B in FIGS. 14 and 15, the protrusion and the peripheral protrusion The height (H) means the height of the central part of the cross section cut in the width direction.

The width (W ₁ ) of the protrusion and the width (W ₂ ) of the peripheral protrusion preferably satisfy the relationship of W ₂ <W ₁ . By satisfying the relationship of W ₂ <W ₁ , it is possible to suppress the area of the peripheral region from becoming too large when causing the contrast between the protrusion and the peripheral region. From the same viewpoint, W ₂ / W ₁ is preferably 0.8 or less, more preferably 0.7 or less, and further preferably 0.5 or less.
In addition, if the width (W ₂ ) of the peripheral protrusion is too small with respect to the width (W ₁ ) of the protrusion, it becomes difficult to form the peripheral protrusion uniformly, or the strength of the peripheral protrusion is reduced. There is a case. _Thus, W 2 / _{W 1} is preferably 0.005 or more, more preferably 0.010 or more.
In the second embodiment of the present specification, the width of the protrusion (W ₁ ) and the width of the peripheral protrusion (W ₂ ) are the structures that form the central protrusion and the peripheral protrusion.

When the length in the width direction is the same as the length in the flow direction, as in the protruding portion 3B in FIGS. ₁ ) and the width of the peripheral protrusion (W ₂ ) refer to the width of the bottom of the cross section cut in the width direction.

The width (W ₁ ) of the protrusion is preferably 1.0 to 10.0 mm, more preferably 1.0 to 7.0 mm, and still more preferably 3.0 to 6.0 mm. .
By setting the width of the protruding portion to 1.0 mm or more, the distinction from the peripheral region becomes clear and alignment can be facilitated. Moreover, the blocking of the first region can be easily suppressed by setting the width of the protruding portion to 1.0 mm or more.
Moreover, it can suppress that the area of a 2nd area | region becomes large more than necessary by making the width | variety of a protrusion part into 10.0 mm or less.

The protrusion has a ratio of height (H) to width (W ₁ ) of 1: 10,000 to 1:10 from the viewpoint of the balance between the effects of height (H) and width (W ₁ ) described above. Preferably, it is 1: 3,000 to 1: 140, more preferably 1: 1,350 to 1: 500.

In the second region R _2A of FIG. 13 and FIG. 16, the row-

like structures

3 and 3A are continuously extended without interruption, but like the second region R _2A of FIG. 14 and FIG. The structure 3A may be intermittently extended to form a peripheral region between the structures. When the columnar structure is extended intermittently, alignment in two directions is possible, and alignment accuracy can be improved.
When the columnar structures are intermittently stretched, the interval (P ₃ ) between the ends of each structure is preferably 1.0 to 10.0 mm, and is 1.0 to 7.0 mm. More preferably, the thickness is 3.0 to 6.0 mm.

Further, it is more preferable that the protruding portion has a substantially quadrangular shape whose outer edge shape has a straight line parallel to the width direction and the flow direction of the transfer sheet. By setting the protruding portion as such a configuration, it is possible to facilitate alignment in both the width direction and the flow direction.
When the protruding portion has a substantially square shape, the length of one side is preferably 2 to 20 mm, more preferably 3 to 15 mm, and further preferably 5 to 10 mm.

Moreover, although not shown in figure, the protrusion part may have any one or more shapes chosen from polygonal shapes, such as a triangular shape, square shape, and pentagon shape, circular shape, and elliptical shape as the outer edge shape.

By combining the shapes of the protrusions and the peripheral protrusions as described above, alignment by shape matching by image processing is also possible.

It is preferable that the peripheral protrusion is formed from a columnar structure extending in an arbitrary direction. The arbitrary direction is not particularly limited, and may be an oblique direction (for example, 45 degrees with respect to the width direction of the transfer sheet). However, as shown in FIGS. 13 to 16, any one side of the transfer sheet 100 Is preferably parallel to the flow direction, and more preferably in the flow direction of the transfer sheet 100. By making the peripheral protrusions 4 have this configuration, alignment can be facilitated.
Moreover, it is preferable that the directions of the plurality of peripheral protrusions are parallel to each other.
Further, the

peripheral protrusions

4, 4 A, 4 B are formed continuously without interruption in any direction in the second region, like the second region R ₂ in FIG. 13 and the second region R _{2A in} FIG. 16. it may be, but the second region _R 2A of FIG. 14 and FIG. _{15, R 2B,} as in the second region _{R 2B} in FIG. 16, the projecting portions 3A, may be divided at a position overlapping with 3B.

More preferably, it is 140 or less. By setting the ratio to 400 or less, it is possible to easily prevent the colored layer from adhering to the peripheral region other than the peripheral protrusion due to the soiling caused by the printing pressure or the like. On the other hand, if the ratio is too small, it is difficult to form the peripheral protrusions uniformly. For this reason, the ratio is preferably 2 or more, more preferably 10 or more, and further preferably 20 or more.

[Fourth Embodiment]
When printing a pattern for alignment after the transfer sheet is completed, the present inventors arrange the pattern for alignment on the release sheet in order to solve the problem that the number of steps is complicated. This was proposed in Japanese Patent Application No. 2016-168148. Further, as a result of further investigation by the present inventors, in this configuration, when the alignment pattern is read, it is difficult to recognize the pattern due to the layer stacked on the alignment pattern. There was a room for improvement.
The fourth embodiment of the present invention has been made in view of such a situation, and improves transferability of a pattern for alignment and can transfer a transfer layer to an accurate position of an object to be transferred. It is an object to provide a sheet, a method for producing the transfer sheet, and a method for producing a decorative molded product using the transfer sheet.

[Transfer sheet]
As shown in FIG. 26, the transfer sheet 100 according to the fourth embodiment of the present invention is a transfer sheet having a transfer layer 20 on the release sheet 10, and the release sheet 10 is a transfer object. a second region R ₂ base layer 11 having a for providing the first region R ₁ and the alignment pattern for transferring, to the second region R ₂ of the base layer 11, transfer layer 20 side The transfer layer 20 includes an alignment pattern portion AL having a follow-up protruding portion 25 based on the convex portion 24 on the surface opposite to the release sheet 10. is there.
In the fourth embodiment, description of what is substantially the same as the first embodiment is omitted.

<Release sheet>
The release sheet 10 includes a base material layer 11 and a release layer 13. The release sheet 10 is peeled off after the transfer layer 20 is transferred to a transfer object such as a resin molded body.

(Base material layer)
The base material layer 11 is formed from the support body 1 and the resin layer 2, for example, as shown in FIG. The base material layer 11 may be a single layer of the support 1 or the resin layer 2, or may have a configuration of three or more layers having layers other than the support 1 and the resin layer 2.
Further, although not shown, the base material layer 11 may further have other regions on the surface on the transfer layer 20 side.

<Support>
As the support 1, the same one as described in the first embodiment can be used.

<Resin layer>
The resin layer 2 can be the same as that described in the first embodiment.

(First area)
The first region R ₁ of the base layer 11 is a region for providing the transfer layer 20 to be transferred to the transfer target.
Surface shape of the first region R ₁ is not particularly limited. Surface shape of the first region R ₁ is, for example, as shown in FIG. 26, may have an irregular shape, may be substantially smooth.
As shown in FIG. 26, when the concavo-convex portion 5 is provided in the first region R ₁ , the transfer layer 20 having a shape complementary to the concavo-convex portion 5 (the release layer 13 on the concavo-convex portion 5 is included). , The transfer layer 20) having a concavo-convex complementary shape alleviated by the release layer 13 is transferred, and the concavo-convex shape can be imparted to the surface of the resulting decorative molded product.
Further, when the surface shape of the first region R ₁ is substantially smooth, increasing the substantially can be made smooth, gloss resulting decorative molded article surface shape of the transfer layer 20 has been transferred to the transfer target Can do.

(Second area)
The second region R ₂ of the base material layer 11 is a region for providing the for alignment used to transfer the transfer target pattern (alignment marks).
The second region R ₂ has a partially deployed convex portion 24 to the basis of the alignment pattern. The convex part 24 is preferably formed in the resin layer 2 by shaping using a plate having a shape complementary to the second region R ₂ from the viewpoint of forming an accurate and precise shape.

The height h of the convex portion 24 is 1.0 to 6.0 μm. When the height h of the convex portion 24 is less than 1.0 μm, it is difficult to maintain the shape of the convex portion 24 every time the convex portion 24 is laminated, and the convex portion 24 is formed on the surface of the transfer layer 20. It becomes difficult to form the follow-up protrusion 25 as a base. If the follow-up protrusion 25 based on the convex portion 24 cannot be formed on the surface of the transfer layer 20, the photoelectric sensor cannot detect the light amount difference between the convex portion and the concave portion, and the pattern position for alignment is determined. It cannot be detected. In addition, since the height h of the convex portion 24 is more than 6.0 μm, when laminating on the convex portion 24, the contact pressure of the convex portion 24 becomes high and a lot of ink rides on the convex portion 24, The bottom of the layer laminated on the convex portion 24 is likely to spread, and light is diffused at the bottom to adversely affect the alignment. And since the height h of the convex part 24 is more than 6.0 μm, the convex part 24 may be deformed by a load at the time of stacking on the convex part 24. It becomes difficult to maintain the accuracy of alignment.
The height h of the convex portion 24 is preferably 1.5 to 5.5 μm, more preferably 2.0 to 5.0 μm from the viewpoint of forming the follow-up protrusion 25 having a desired shape. More preferably, it is 2.5 to 4.5 μm.
The heights h of the convex portions 24 may not be the same. However, from the viewpoint of facilitating uniform formation of the height H of the tracking protrusion 25, it is preferable that all the heights h of the protrusions 24 be the same or approximate values.
In addition, in this specification, the height h of the convex part 24 means the structure forming the convex part 24 from the reference plane of the base material layer 11 having a cross section cut in a direction perpendicular to the extending direction of the structural body. The height of the center.

The distance d between the end portions of the convex portion 24 is 10 to 500 μm. When the distance d between the end portions of the convex portion 24 is less than 10 μm, a skirt is formed due to the influence of ink dripping between the end portions of the convex portion 24 when laminating on the convex portion 24. It becomes difficult to maintain the accuracy of alignment. Further, the tracking protrusions 25 based on the protrusions 24 adjacent to the surface of the transfer layer 20 may be connected to each other, and if the individual tracking protrusions 25 cannot be recognized, the alignment accuracy is maintained. Difficult to do. Further, since the distance d between the end portions of the convex portions 24 is more than 500 μm, when the layers are stacked on the convex portions 24, the contact pressure of the convex portions 24 is increased and a large amount of ink is loaded on the convex portions 24. In addition, the skirt of the layer laminated on the convex portion 24 is likely to spread, and light is diffused at the skirt to adversely affect the alignment. By spacing d of ends of the convex portion 24 is 500μm greater than the alignment mark is increased, it is necessary widely reserved unnecessarily second region area of R _2, is a design problem is there.
Interval d of ends of the convex portion 24 improves the recognition rate of the alignment mark, from the viewpoint of suppressing the area of the second region R ₂ is wider than necessary, preferably from 15 ~ 450 [mu] m, It is more preferably 20 to 400 μm, and further preferably 25 to 350 μm.
In the present specification, the distance d between the ends of the convex portion 24 refers to the distance between the ends of the bottom of the convex portion 24.

The ratio h / d between the height h of the convex portion 24 and the distance d between the end portions of the convex portion 24 is preferably 0.003 to 0.100, and preferably 0.005 to 0.080. More preferably, it is 0.007 to 0.060.
By setting the ratio h / d within the above range, the balance between the height h of the convex portion 24 and the distance d between the end portions of the convex portion 24 becomes good, and a skirt is formed between the end portions of the convex portion 24. This makes it difficult to perform positioning and improves the alignment accuracy.

The width b of the convex portion 24 is preferably 5 to 200 μm, more preferably 10 to 150 μm, and even more preferably 15 to 100 μm. By setting the width b of the convex portion 24 to 5 μm or more, the strength of the convex portion 24 can be maintained and the convex portion 24 can be easily formed uniformly. Further, by setting the width b of the protrusion 24 and 200μm or less, that the area of the second region R ₂ is wider than necessary it can be suppressed.
In addition, in this specification, as shown in FIG. 28, the width b of the convex part 4 is a direction orthogonal to the extending direction of the structural body when the structural body forming the convex part 4 is a linear structure. The width of the cut section. And the width b of the convex part 4 means the width | variety of the cross section cut | disconnected in the major axis direction of the structure, when the structure which forms the convex part 4 is a dot-like structure, as shown in FIG. .

The ratio h / b between the height h of the convex portion and the width b of the convex portion is preferably 0.010 to 0.050, more preferably 0.015 to 0.045, and more preferably 0.020. More preferably, it is ˜0.040.
By the ratio h / b 0.010 or more, it can suppress the area of the second region R ₂ is wider than necessary. Further, by setting the ratio h / b to 0.050 or less, it is possible to easily form the follow-up protrusion 25 that maintains the shape of the protrusion 24.

The convex part 24 can be formed from a line-shaped structure, a dot-shaped structure or the like extending in an arbitrary direction, and is preferably formed from a line-shaped structure. The arbitrary direction is not particularly limited and may be an oblique direction (for example, 45 degrees with respect to the width direction of the transfer sheet), but is preferably a direction parallel to any one side of the transfer sheet 100. The flow direction of the transfer sheet 100 is more preferable. By making the convex portion 24 have this configuration, alignment can be facilitated.
Moreover, it is preferable that each direction of the some convex part 24 is parallel.
Further, the convex portion 24 may be formed continuously without interruption in any direction in the second inner region R _2, but may be one that extends in any direction partially interrupted.

Transfer sheet 100 of the present embodiment may have a second region R ₂ of two or more. If a second region R ₂ of two or more, it is preferable to change the role of each area. For example, when having a plurality of second regions R _2, either one aligns the width direction, it is preferably configured to perform the alignment of the flow direction in the other. By configuring the second region R ₂ as described above, it is possible to align in both directions in the width direction and the flow direction, thereby improving the accuracy of alignment.
In the transfer sheet 100 of the present embodiment, as shown in FIG. 27, the second region R ₂ is provided on both sides of the first region R ₁ , and the alignment pattern portion (alignment mark) AL is the uneven portion 5. It is preferable to be provided on both sides. Since the alignment pattern portion AL is provided on both sides of the uneven portion 5, the position in the width direction of the alignment pattern portion AL with respect to the uneven portion 5 can be changed regardless of the number of times the transfer sheet 100 is rewound. Therefore, the alignment accuracy can be increased, and the productivity can be improved.

(Release layer)
The release sheet 10 of the transfer sheet 100 is formed so as to be peelable at the interface with the transfer layer 20 when it is in close contact with the transfer object. In order to improve the releasability, the release sheet 10 preferably has a release layer 13 on at least a part of the surface in contact with the transfer layer 20. Further, from the viewpoint of uniform release property within the surface of the transfer sheet 100, the release sheet 10 has a release layer 13 on the entire surface in contact with the transfer layer 20, as shown in FIG. It is preferable.

The release layer 13 may be the same as that described in the first embodiment.

<Transfer layer>
