However, the above (1)
The transfer sheet using a vinyl chloride resin as the support sheet has the following problems. That is, in the transfer sheet, since the picture layer serving as the transfer layer is directly printed on the support sheet, the solvent of the ink attacks the support sheet during printing, and the peel strength becomes unstable. In the transfer sheet, the plasticizer bleeds out of the vinyl chloride resin film of the support sheet, and the peel strength becomes unstable.
In the transfer sheet, the resin used for the release layer in contact with the support sheet is limited to polyvinyl butyral and cellulose acetate propionate.

Further, as described in (2) above, in a transfer sheet using a support sheet other than a vinyl chloride resin, it is necessary to use a support sheet provided with an anchor layer made of a urethane resin. And the suitable molding temperature range is narrowed. Further, as described in (3) above, in a transfer sheet using a polyolefin-based resin as the support sheet, the polyolefin-based resin used has high crystallinity. In the case of transfer to an uneven surface, the temperature range in which molding can be performed sufficiently on the uneven surface is narrow because of the sharp increase in the property. In addition, the pattern is easily distorted and the transfer sheet is easily broken due to local concentration (necking) of elongation during molding. Further, as in the above (4), in the transfer sheet in which the polyolefin-based resin of the support sheet is a thermoplastic elastomer, the moldability is surely improved by the use of the elastomer. However, on the other hand, the peel strength increases, and the peelability of the transfer layer deteriorates.

Further, as described in the above (5), in a transfer sheet in which the polyolefin resin layer of the support sheet is formed into a multilayer structure to achieve both moldability and releasability, contrary to expectation, amorphous propylene Even with the moldability of the copolymer layer, it was completely impossible to compensate for the lack of moldability of the crystalline polypropylene or crystalline polyethylene layer. In particular, when applied to the case of a large uneven step and a three-dimensional uneven shape, the lack of moldability becomes conspicuous.

By employing such a structure of the support sheet, it is possible to achieve both the moldability and the releasability of the transfer sheet. In particular, in the form of a three-layer structure, it is possible to prevent the occurrence of blocking during winding and storage, and to more reliably impart anti-blocking properties. In addition, due to differences in heat shrinkage and elongation that can occur in the case of a two-layer structure, Warpage and curling during production, storage, use and the like can also be effectively prevented. For this reason, in the three-layer configuration, setting of the transfer sheet to the molding machine becomes easy.

The ethylene content of the ethylene-propylene random copolymer layer used for the layer A not in contact with the transfer layer is adjusted to an appropriate value in consideration of moldability. When the ethylene content is increased, the crystallinity is reduced, and the moldability is increased (note that the peel strength is also increased irrespective of the layer A which is not in contact with the transfer layer). The ethylene content is about 5 to 50% on a mass basis, and usually about 30%.

On the other hand, a propylene copolymer resin having no stereoregularity is a resin usually used as a soft component (soft segment), and improves moldability. Further, by increasing the ratio in the resin composition, the peel strength is increased, so that the peelability can be adjusted. Examples of such a propylene copolymer resin having no stereoregularity include propylene-ethylene copolymer, propylene- (1-butene) copolymer, and propylene- (1-butene) -ethylene terpolymer. Propylene- (1-hexene)-(1-octene) terpolymer, propylene- (1-hexene)-
(4-Methyl-1-pentene) terpolymer and the like can be used. These copolymers are used as one kind or as a mixed resin of two or more kinds. The amount of the propylene copolymer resin having no stereoregularity is calculated as follows: [crystalline polypropylene resin / propylene copolymer resin having no stereoregularity] =

Further, since the surface layer 11 using the layer B is a layer that imparts a certain degree of moldability, though insufficient, together with a layer that imparts good releasability as a surface physical property, it can be reliably formed into a film. In addition, it is only necessary to have a minimum thickness necessary for performing stable peeling. If the thickness is too large, the moldability of the entire support sheet is reduced. Therefore, the thickness is usually at least about 5 μm and at most about 20% of the total thickness of the support sheet. In this connection, since the intermediate layer 13 in the three-layer structure using the A layer and the back layer 12 in the two-layer structure are layers which give moldability preferentially, they are transferred. Thickness (thickness ratio is large) is preferable as long as layer separation is not hindered. Therefore, even in the case of a three-layer structure, the thickness is at least 60% of the total thickness of the support sheet.

Further, an uneven pattern may be provided on the surface of the support sheet. For example, if an uneven pattern such as a squeezed pattern is provided on the back surface (the side of the support sheet that does not face the transfer layer), it is possible to improve the anti-blocking property when wound up and the slipperiness of the molding transfer sheet. If an uneven pattern such as a squeezed pattern is provided on the surface (the surface facing the transfer layer) (the surface on which the transfer layer is formed is made of a polyolefin-based resin and is relatively difficult to wet), the transfer layer is printed.

The solid particles are ejected from the ejector toward the transfer sheet for molding, and the collision pressure that collides with the transfer sheet for molding becomes the transfer pressure. Typically, an impeller or a blowing nozzle is used for the ejector. The impeller accelerates the solid particles by its rotation, and the blowing nozzle accelerates the solid particles with a high-speed fluid flow. Sandblasting, shot blasting, shot peening and the like used in the blasting field can be used for the impeller and the blowing nozzle. For example, a centrifugal blast device is used for the impeller, and a pressurized or suction blast device, a wet blast device, or the like is used for the blowing nozzle. The centrifugal blast device accelerates and ejects solid particles by the rotational force of the impeller. A pressurized blasting device ejects solid particles together with air while being mixed with compressed air. The suction-type blast device sucks solid particles into a negative pressure portion generated by a high-speed flow of compressed air, and ejects the solid particles together with the air. The wet blast device mixes and ejects solid particles with a liquid. Among these, the impeller is one of the efficient and preferable ejectors in that the ejection amount of solid particles is large.

FIG. 4 and FIG. 5 are conceptual diagrams showing an example of the ejector using the impeller. The impeller 812 includes a plurality of impellers 8.
13 is fixed on both sides by two side plates 814, and the center of rotation is a hollow portion 815 without the blade 813. Further, a direction controller 816 is provided inside the hollow portion 815 (see FIG. 5). The direction controller 816 has an opening 817 that is partially open in the circumferential direction, has a hollow cylindrical shape, and has the same rotation axis as the rotation axis of the impeller 812, and rotates independently of the impeller. It is free. When using the impeller, the opening of the direction controller is fixed so as to face an appropriate direction, and the ejection direction of the solid particles is adjusted. Further, inside the directional controller, another impeller, which is hollow inside and has the same rotation axis as the rotation axis of the impeller 812, is provided as a sprayer 818 (see FIG. 5). The spreader 818 rotates with the outer impeller 812. A rotation shaft 819 is fixed to the center of rotation of the side plate 814, and the rotation shaft 819 has a bearing 820.
A rotary power source such as an electric motor that is rotatably supported by a motor (not shown)
, And the impeller 812 rotates. The rotating shaft 819 does not penetrate between the two side plates 814 having the blades 813 therebetween, and forms a space without a shaft. Then, the solid particles P are supplied into the sprayer 818 from a hopper or the like through a transport pipe. Usually, the solid particles are supplied from above (directly above or obliquely above) the impeller. The solid particles supplied into the sprayer are scattered outward by the impeller of the sprayer. The scattered solid particles are emitted only in the direction allowed by the opening 817 of the direction controller 816 and supplied between the blades 813 of the outer impeller 812. Then, it collides with the blade 813 and the impeller 812
It is accelerated by the rotational force of the gas and squirts from the impeller.

Next, FIG. 6 is a conceptual diagram showing an example of an ejector using an ejection nozzle. An ejector 840 shown in the figure is an example of an ejector in which a gas such as air is used as a solid particle accelerating fluid, and the gas and the solid particles are mixed and ejected when ejecting the solid particles. The ejector 840 includes an induction chamber 841 that mixes the solid particles P and the fluid F, an internal nozzle 842 that ejects the fluid into the induction chamber, and an ejection nozzle unit 844 that ejects the solid particles and the fluid from the nozzle opening 843. A fluid F in a pressurized state from a compressor or the like is ejected from an internal nozzle 842, passes through an induction chamber 841 and passes through a nozzle opening 84 of a nozzle 844.
3, a negative pressure is created by the action of a fluid flow flowing at a high speed in the guide chamber 841 in the ejector, and the negative pressure guides and mixes the solid particles into the fluid flow, thereby forming the solid particles in the fluid flow. It accelerates, conveys, and jets out together with the fluid flow from the nozzle opening 843 of the nozzle 844. In addition, there is a blowing nozzle or the like that uses a liquid as a solid particle acceleration fluid. The fluid pressure is generally about 0.01 to 1 MPa as a spray pressure. The flow velocity of the fluid flow is usually about 1 to 20 m / sec for the liquid flow, and is usually about 5 to 80 m / sec for the air flow.

If the pressurized area cannot be formed into a desired shape and size by using only one ejector, a plurality of ejectors are used. Further, when actually transferring using solid particles, it is preferable that the solid particles are not scattered in the surrounding atmosphere and circulated and reused. May be caused to collide with the transfer sheet for molding. The peeling of the support sheet may be performed outside the chamber.

Preferably, the transfer sheet for molding is preliminarily heated and softened by an infrared radiation heater or the like to impart stretchability. When the transfer object has a large heat capacity, it is preheated in advance, and a heat-sealing adhesive is used. The layer acting as a layer (depending on the case, a picture layer, an adhesive layer, etc.) is made to collide solid particles with the transfer sheet for molding in a state of being heat-activated. When transferring by thermal fusion, the timing of heating to activate and thermally fuse a layer to be thermally fused, such as an adhesive layer, is before applying the collision pressure, during the application of the collision pressure, or before applying the collision pressure. And during application. On the other hand, if the transfer sheet for molding follows the surface shape of the transferred object and is formed, and the transfer layer is sufficiently in contact with the transferred object, cooling of the heat-sealed layer by cooling means such as cold air is promoted. Is also good. The cool air is blown from, for example, the molding transfer sheet side or the transfer receiving body side.
