Abstract

PURPOSE:To avoid the generation of wrinkles on a foil member, by energizing the rear side of said foil member to the direction opposite to the transferring direction thereof when a supporting member and said foil member are held and transferred. CONSTITUTION:A supporting member 2 having a stereoscopic toner image formed therein and a foil member 3 are held by a carrier sheet 4 in the overlapped state. The carrier sheet 4 is then sent into a transferring device to be held and transferred by a rotating heating/pressuring roller 11. At this time, when the leading end of the carrier sheet 4 is detected as passing through a sensor, the sensor outputs a detection signal, based on which a suction fan and a pair of brush rollers 14, 15 are actuated. Because of the actuation of the suction fan, the rear side of the foil member 3 to be held henceforth is sucked to a suction surface of a sucking member 13, and at the same time, the opposite lateral sides of the foil member 3 are pushed backward and outward by the pair of the brush rollers 14, 15. As a result, the foil member 3 can be held and transferred by the heating/pressuring roller 11 without generating wrinkles, and a toner 24 of the toner image on the supporting member 2 is melted and adhered to an adhesive layer of the foil member 3, thus realizing favorable transfer of the foil member.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method of foiling and transferring a three-dimensional image.

[Prior Art] Conventionally, the foiling transfer method disclosed in, for example, Japanese Unexamined Patent Publication No. 61-252190@ and US Pat. No. 4,006,267 has been known. These foil material transfer methods use a support such as a postcard or card on which a toner image has been formed using a copying machine, etc., and a foil body having a colored material layer and superimposing the colored material layer on the toner image surface. The toner is conveyed while being held between heated and pressurized rollers, and a part of the coloring material layer is selectively transferred to the toner image by utilizing the toner welding caused by the heating.

For example, in Japanese Patent Publication No. 59-35359, there is a copy I
A toner image with good light absorption is formed on a heat-expandable sheet using a method such as a, and the surface on which the toner image is formed is irradiated with light to selectively heat and bulge the toner image area, thereby forming a three-dimensional image. A method is disclosed.

[Problems to be Solved by the Invention] When transferring a three-dimensional image onto a support using the conventional method described above, wrinkles may occur in the foil when it is held and conveyed by heating and pressure rollers. As a result, a problem has arisen in that good placement on a stereoscopic image may not be transferred.

SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned problems, and its purpose is to provide a method for transferring a three-dimensional image to a three-dimensional image, which enables good transfer.

Shia! Means for Solving Two Problems 1 The method of transferring a three-dimensional image according to the present invention consists of a support on which a convex toner image with toner adhered, at least a coloring material layer and an adhesive layer. and a foil body in which the adhesive layer is superimposed on the toner image surface, and the toner image is selectively colored by using heating and welding of the toner, by sandwiching and conveying the foil body with the adhesive layer superimposed on the toner image surface. Transferring a part of the material layer to a three-dimensional image is a transfer method, and when the support and the foil are being conveyed while being sandwiched, the backward side of the foil that will be sandwiched from now on is at least opposite to the conveying direction. It is characterized in that it is carried out by being biased in the direction.

[Function] In the transfer method of the present invention, when attaching to a three-dimensional image, when the support and the foil are being conveyed while being sandwiched, the backward side of the foil that will be sandwiched from now on is moved in the opposite direction to the conveying direction or in this direction. In addition, it is biased in both directions. This applies tension to the foil and keeps it in a state where wrinkles are less likely to occur.

[Example] In the following, specific examples of the transfer method of the present invention will be explained based on the drawings.
