  INDUSTRIAL APPLICABILITY The present invention can provide a projection toy having high playability in which unexpectedness and changeability are imparted to an image of light projected by application of water or the like, and a projection toy set using the same.

It is longitudinal section explanatory drawing of one Example of the projection toy of this invention. It is longitudinal cross-sectional explanatory drawing of the other Example of the projection toy of this invention.

The present invention provides a discoloration in which a low-refractive-index pigment is fixed to a binder resin in a dispersed state on a light-transmitting support surface, and a porous layer having different light-transmitting properties in a liquid-absorbing state and a non-liquid-absorbing state is provided. A projection toy comprising a body and a light source disposed behind the discoloration body.
The light from the light source is either completely blocked by the discolored body, or partially transmitted and projected on the ceiling or wall surface. When water is attached to the discolored body in this state, the porous layer becomes transparent and an image is formed by light, and the image is projected on the ceiling or wall surface.
As the porous layer dries, the light image becomes invisible, and the light image projected on the ceiling or wall surface becomes invisible.
Further, when the light composition from the light source is completely blocked by the discolored body, or the liquid composition described later is attached to the discolored body from a state where it is partially transmitted and projected on the ceiling or wall surface, the porous layer Becomes transparent and a clear image is formed by light, and the image is projected on the ceiling or wall surface.
In addition, when a liquid composition in which a solid material having a refractive index of 1.3 to 1.8 is dissolved or dispersed in a medium is used, a light image is visually recognized even when the porous layer is dried, and the light is visible on the ceiling or wall surface. The projected image of the light is also maintained.

The support constituting the discoloration body can be any material as long as it has a light transmitting property, and examples thereof include glass, plastic, and porcelain.
Examples of the plastic include plastic molded articles such as polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polymethyl methacrylate, polyacrylate, polystyrene, polycarbonate, cellulose triacetate, cellulose diacetate, polyvinyl alcohol, and polyamide.
The support may be translucent or colored and transparent as well as colorless and transparent as long as it has translucency.
Examples of the shape of the support include a sphere, a hemisphere, a square, a rectangle, a cone, a pyramid such as a triangular pyramid and a quadrangular pyramid, a cylinder, a prism such as a triangular prism and a quadrangular prism, a truncated cone, a truncated pyramid, and a half prism In addition to the shape, it may be a shape imitating a doll, animal, plant, vehicle, building, star, food, or the like.
Oh, it is preferable that the said support body is comprised by the hollow shape, and accommodates a light source inside a support body.
In addition, by providing a driving device that moves the discolored body, an image of light projected on the ceiling or wall surface moves, so that variability can be imparted.

The porous layer provided on the surface of the support is a layer in which a low refractive index pigment is fixed in a dispersed state together with a binder resin, and is a layer having different transparency in a dry state and a liquid absorption state.
Examples of the low refractive index pigment include silicic acid and salts thereof, barite powder, barium sulfate, barium carbonate, calcium carbonate, gypsum, clay, talc, alumina white, magnesium carbonate, and the like. It is in the range of 1.8, and shows good transparency when water is absorbed.
Examples of the silicic acid salt include aluminum silicate, aluminum potassium silicate, sodium aluminum silicate, aluminum calcium silicate, potassium silicate, calcium silicate, sodium calcium silicate, sodium silicate, magnesium silicate, and potassium magnesium silicate.
Two or more of the low refractive index pigments can be used in combination.
The particle size of the low refractive index pigment is not particularly limited, but 0.03 to 10.0 μm is preferably used.
In addition, silicic acid is mentioned as a low refractive index pigment used suitably.
The silicic acid may be a silicic acid produced by a dry process, but a silicic acid produced by a wet process (hereinafter referred to as a wet process silicic acid) is particularly effective. To explain this point, silicic acid is amorphous. Amorphous silicic acid produced by a dry process using a gas phase reaction such as thermal decomposition of silicon halide such as silicon tetrachloride (hereinafter referred to as dry process silicic acid), and sodium silicate. It is roughly divided into those using a wet method using a liquid phase reaction such as decomposition by an acid such as a dry method, and the structure of a dry method silicic acid is different from that of a wet method silicic acid. The dry method silicic acid has a three-dimensional structure in which silicic acid is closely bound. In contrast, wet-process silicic acid has a so-called two-dimensional structure part in which silicic acid is condensed to form a long molecular arrangement.
Therefore, since the molecular structure becomes rough compared to the dry method silicic acid, when wet method silicic acid is applied to the porous layer, it is excellent in the diffused reflection of light in the dry state compared to the system using the dry method silicic acid, Therefore, it is guessed that the concealment property in a normal state becomes large.
Further, since the porous layer mainly absorbs water, the wet method silicic acid has more hydroxyl groups present as silanol groups on the particle surface than the dry method silicic acid, and the degree of hydrophilicity is large. Yes, it is preferably used.
In addition, in order to adjust the concealability in the normal state of the porous layer and the transparency in the liquid absorption state, other general-purpose low-refractive-index pigments can be used in combination with the wet method silicic acid.

The low refractive index pigment in the porous layer depends on properties such as particle diameter, specific surface area, oil absorption, etc., in order to satisfy both the concealability in the normal state and the transparency in the liquid absorption state, preferably the coating amount is ^{1g / m 2 ~30g / m 2} , more ^{preferably 5g / m 2 ~20g / m 2} . If it is less than 1 g / m ² , it is difficult to obtain sufficient concealability in a normal state, and if it exceeds 30 g / m ² , it is difficult to obtain sufficient transparency during liquid absorption.
The low refractive index pigment is dispersed in a vehicle containing a binder resin as a binder, applied to a translucent support, and then the volatile matter is dried to form a porous layer.
Examples of the binder resin include urethane resin, nylon resin, vinyl acetate resin, acrylic ester resin, acrylic ester copolymer resin, acrylic polyol resin, vinyl chloride-vinyl acetate copolymer resin, maleic resin, polyester resin, styrene. Resin, styrene copolymer resin, polyethylene resin, polycarbonate resin, epoxy resin, styrene-butadiene copolymer resin, acrylonitrile-butadiene copolymer resin, methyl methacrylate-butadiene copolymer resin, butadiene resin, chloroprene resin, melamine resin, and the above Each resin emulsion, casein, starch, cellulose derivative, polyvinyl alcohol, urea resin, phenol resin and the like can be mentioned.
The mixing ratio of the low refractive index pigment and these binder resins depends on the type and properties of the low refractive index pigment, but preferably the binder resin solid content is 0.5 to 1 part by mass with respect to 1 part by mass of the low refractive index pigment. 2 parts by mass, and more preferably 0.8 to 1.5 parts by mass. When the binder resin solid content is less than 0.5 parts by mass with respect to 1 part by mass of the low refractive index pigment, it is difficult to obtain a practical film strength of the porous layer, and the content exceeds 2 parts by mass. In this case, the water permeability into the porous layer is deteriorated.
Since the porous layer has a smaller mixing ratio of the binder resin to the colorant than a general coating film, it is difficult to obtain sufficient film strength. Therefore, in order to increase the scratch resistance, it is effective to use a nylon resin or a urethane resin among the binder resins.
Examples of the urethane resin include a polyester urethane resin, a polycarbonate urethane resin, and a polyether urethane resin, and two or more of them can be used in combination. In addition, a urethane emulsion resin in which the resin is emulsified and dispersed in water, or a colloid in which the resin is self-emulsified without the need for an emulsifier by an ionic group of the ionic urethane resin (urethane ionomer) itself and dissolved or dispersed in water. A dispersion type (ionomer type) urethane resin can also be used.
The urethane-based resin may be either an aqueous urethane-based resin or an oil-based urethane-based resin, but in the present invention, an aqueous urethane-based resin, in particular, a urethane-based emulsion resin or a colloidally dispersed urethane-based resin is suitable. Used for.
The urethane resin can be used alone, but other binder resins can be used in combination depending on the type of translucent support and the performance required for the film. When a binder resin other than the urethane resin is used in combination, in order to obtain a practical film strength, it is preferable to contain 30% or more of the urethane resin in a solid mass ratio in the binder resin of the porous layer.
In the binder resin, the crosslinkable resin can be further improved in film strength by adding an arbitrary crosslinking agent and crosslinking.
The binder resin has a large or small affinity with water. By combining these, the penetration time into the porous layer, the degree of penetration, and the slow speed of drying after the penetration can be adjusted. Furthermore, the said adjustment can be controlled by adding a dispersing agent and surfactant suitably.

  The porous layer can be formed on the support surface by brush coating, spray coating, electrostatic coating, electrodeposition coating, flow coating, roller coating, dip coating, or the like.

The color change material may contain a colorant in the support or the porous layer so that the color change can be varied.
Moreover, a color change can also be made various by providing the colored layer which has translucency which contains a coloring agent in the back surface of a support body between the said support body and a porous layer.
As the colorant, a fluorescent pigment or a fluorescent dye can be used in addition to a general colored dye or pigment.

In the present invention, a light source is disposed behind the color changing body.
Examples of the light source include incandescent bulbs, halogen bulbs, fluorescent lamps, metahalide lamps, sodium lamps, discharge lamps such as mercury lamps, light emitting diodes, and laser light.
In addition, the light source is not limited to the one that always lights up, it blinks, or it can be switched between always lighting and blinking to give variability, or the light source itself moves with a driving device. Rotation can also be applied.
By changing the color of the light source, the color of the image projected on the ceiling or wall surface can be changed.
As means for changing the color of the light source, a plurality of light sources having different colors are provided so that a single light source can selectively emit light, or a plurality of light sources can emit light simultaneously, or a color filter that changes the color of the light source The structure which interposes between a light source and a discoloration body is mentioned.

The light source may be configured to be exposed to the outside, or may be configured to be accommodated in a container or the like.
Examples of the material in the container include plastic, glass, rubber, metal, wood, ceramics, and stone materials.
Examples of the container include a hollow container, in which a light source is accommodated.
Specifically, a configuration in which a light source is housed in a container and light from the light source is irradiated on the back surface of the discoloration body is exemplified.
As a power source for causing the light source to emit light, a method of supplying power from an outlet or using a power source such as a dry battery can be mentioned. is there.
The dry battery may be either a primary battery or a secondary battery, and electricity can be obtained from a solar battery.

A translucent pattern body may be disposed between the color changing body and the light source.
By providing the translucent pattern body, the pattern by the translucent pattern body is projected on the ceiling or wall surface through the discolored body.
When water is attached to the discolored body, the porous layer becomes transparent and an image is formed by light, and an image combined with the translucent pattern is displayed on the ceiling or wall surface.
As the porous layer dries, the image by light becomes invisible, and the image projected on the ceiling and wall surface becomes invisible, and only the pattern by the translucent pattern is visible.
The translucent pattern body is a translucent sheet provided with various characters, symbols, figures, patterns, and the like.
Furthermore, a plurality of translucent pattern bodies having different patterns can be detachably configured to project various patterns.
By providing the driving device that moves the translucent pattern body, the pattern by the translucent pattern body projected on the ceiling or the wall surface moves, so that variability can be imparted.

  The image by the projection toy can be projected on the ceiling or wall surface, but by selecting a place to use even if it does not have a ceiling or wall surface by providing a screen for projecting a light image (projected image). You can play without.

A projection toy set is obtained by combining the water adhering means and the projection toy.
In addition, as a preferable water adhesion means, it is a writing instrument or applicator to which a plastic porous body or a fiber processed body having continuous pores is applied as a pen tip member, so that a writing image can be easily formed and practicality can be improved.
The plastic porous body or fiber processed body having continuous pores in the above may be any one that absorbs and discharges water in an appropriate amount, and focuses the continuous pore bodies and fibers of polyolefin-based, polyurethane-based and other various plastics. Examples include brush-like ones, those obtained by resin processing or heat welding of fibers, felts, and nonwoven fabrics. The shape and dimensions can be arbitrarily set according to the purpose.

As the liquid composition is gradually dried from the porous layer, the handwritten image formed on the discolored body becomes invisible, so that only the starry sky is visible on the ceiling and wall surface.
When the liquid composition was again adhered to the porous layer, a written image was projected, and this aspect change could be repeated.

Example 13
Production of a projection toy set A projection toy set was obtained by combining the projection toy of Example 3 and a stamping tool in which a liquid paraffin (liquid paraffin produced by KZS Co., Ltd., KZS Co., Ltd.) was accommodated as an attachment tool.
The projection toy has a white color when the porous layer is in a dry state, and the light from the light source causes the rotating pattern of the translucent pattern to pass through the porous layer and be projected on the ceiling or wall surface. The pattern is visible.
When a liquid composition is attached to the porous layer using an attachment tool, it becomes transparent and an image (dolphin picture) is formed, and the image is irradiated with light from a light source from the back side, so that the image has glitter Appears on the discolored body, and the image is projected with a wave pattern on the ceiling and wall.
Since the liquid composition is non-volatile, the formed image is maintained, and thus the image projected on the ceiling and the wall surface is also maintained.
In addition, the image can be removed by washing the porous layer with a detergent, and the image can be formed again by using a stamping tool containing the liquid composition. It was.
