- the surface structure film obtained by the method of the present invention is of micron size, such as an optical film having optical functions such as diffusion, condensing, reflection, and transmission, and a concavo-convex structure film having super-liquid-repellent function and cell culture suitability. It is used as a member that requires a nano-sized microstructure on its surface.
- a mold having a fine structure formed on the surface is used to apply a thermosetting or radiation curable material to the mold or the film before being supplied to the mold. After coating, the film is held in a heated mold to form a fine structure in the coating film and cured, and further, the film is peeled from the mold to form a fine structure on the surface of the film. There is a method of obtaining a surface structure film by transferring.
- Patent Document 1 after applying a sol-gel, which is a thermosetting material, to a film mold drawn out by roll-to-roll, heat treatment is performed while pressing the mold against the substrate, thereby forming a fine structure made of the sol-gel material on the substrate surface.
- a method for transferring to a substrate is described.
- a fine structure is formed in advance on the surface of the film mold, and a structure having substantially the same shape as this fine structure is also formed on the substrate surface. Since the sol-gel material is used, a concavo-convex structure with relatively high heat resistance can be formed.

It is described that the temperature of the first heating roll and the second heating roll can be individually set according to the raw fabric and the foam material used, thereby forming the uneven structure on the raw fabric and foaming the foam material. And it becomes possible to perform lamination
- the manufacturing method of the microstructure transfer film described in Patent Document 1 has a problem that the molding cost is high because a long film roll is used as a mold. Moreover, although it can be applied to a sheet-like substrate, when applied to a roll-to-roll film, the mold and the substrate are peeled off while the thermosetting material is uncured due to shrinkage during heating, and a predetermined surface structure cannot be formed. There was a problem. Even if the film can be cured without being peeled off, the cured material cannot be sufficiently filled up to the inside of the pattern formed on the mold surface in the state where the film and the mold are laminated, resulting in a transferred pattern shape. There was a problem of becoming defective.
- thermosetting material when applied to a material made of a thermosetting material, the mold and the substrate are peeled off while the thermosetting material is uncured due to shrinkage during curing, and a predetermined transfer There was a problem that the surface structure could not be formed.
- the flatness of the thermosetting material applied to the mold surface is poor, poor adhesion between the thermosetting material and the substrate occurs in a state of being laminated with the substrate, and the thermosetting material is uniformly distributed on the substrate. There was a problem that it was not transferred.
- both the first heating roll and the second heating roll need to be at a high temperature, and maintenance of the uneven structure of the original fabric that is a thermoplastic resin

Moreover, in order to maintain the space
- the endless belt-shaped mold 12 is an endless belt having an uneven surface structure.
- a flexible one is preferable because it can be held on the roll during the conveyance process.
- a thin and uniform material is preferable.
- As the shape a surface structure having a height difference of 1 mm or less is preferable in consideration of deformation time and curing time of the thermosetting material to be applied. Moreover, since it heats during conveyance, the material which can endure heating temperature is preferable.

- the thermosetting material A13 is apply
- the thermosetting material B13 ′ is applied to the surface of the forming film 11 unwound from the unwinding roll 23 a serving as the film supply means 23 by the film application unit 33. After the application, it is supplied to the surface of the mold 12 in the pressurizing unit 27a.
- the pressing mechanism 27 sandwiches the mold 12, the thermosetting material A13, the thermosetting material B13 ', and the film 11 so as to be sandwiched between the pressing portions 27a.
- thermosetting material A13 is heated and gradually cured immediately after being applied, it is applied to the surface of the mold 12 by being pressurized by the pressure mechanism 27 in a state where the curing is not completely completed. Since the thermosetting material A13 enters into the formed surface structure and at the same time, the surface of the heating roll 21 continues to receive thermal energy, curing is accelerated. On the other hand, under the influence of the concavo-convex structure imparted to the surface of the mold 12, unevenness may occur on the application surface of the thermosetting material A13, but when the mold 12 and the film 11 are bonded together, The applied thermosetting material B13 ′ flows so as to fill the concave portion of the application surface of the thermosetting material A13. As a result, the mold 12, the thermosetting material A13, the thermosetting material B13 ′, and the film 11 are flown. In the laminated body, the layers adhere closely to each other with no gap.
- thermosetting materials A13 and B13 'receive the thermal energy from the mold 12 and the curing is promoted, the thermosetting materials A13 and B13' start to adhere to the film 11 and do not easily peel off.
- the mold 12, the thermosetting materials A13 and B13 ′, and the laminate 14 of the film 11 are conveyed to the second heating roll 22, and the thermosetting materials A13 and B13 ′ are further heated from the heated roll surface.

- the high filling property of the resin means that the resin flows to the gap of the structure formed on the mold surface by nipping at a sufficiently high pressure with respect to the elastic modulus of the thermosetting material A13.
- high flatness means that the end portion in the nip width direction and the flow into the resin in the transport direction are suppressed during pressurization, and a uniform thickness is obtained in both the width direction and the transport direction.
