摘要： PROBLEM TO BE SOLVED: To efficiently manufacture a transfer product such as a decorative material or the like having a three-dimensional protrusion and recess surface. SOLUTION: A decorative material is obtained by opposing a transfer layer side of a transfer sheet S having a support and a transfer layer at a protrusion and recess surface of a base material B to be transferred having the protrusion and recess surface, colliding solid particles P ejected from an ejector 1 with the support side of the sheet S, bringing the sheet S into pressure contact with the material B by its collision pressure, and then releasing the support to obtain the decorative material. In this case, heated solid particles are used to prevent its temperature drop in the case of previously heating the sheet or adhesive to be effectively transfer. The previous heating can be omitted dependent on materials of the sheet and the adhesive.

摘要： PROBLEM TO BE SOLVED: To obtain an uneven feeling more emphasized as compared with actual unevenness and a thick-walled feeling or a profound feeling more emphasized as compared with the original thickness by decorating a variable density region by light and shade generated by surface unevenness at the time of use by a decorative layer forming a variable density surface aligning with the variable density region. SOLUTION: A plurality of coating nozzles 5a, 5b take charge of a plurality of the dark parts 1a and bright parts 2a of a decorative layer corresponding to respective recessed and projected parts. A dark color coating material (a) is sprayed on base material parts having to become dark parts 1a from the coating nozzles 5a while a bright color coating material (b) is sprayed on base material parts having to become bright parts 2a from the coating nozzles 5b to apply coating. The coating of the dark parts and that of the bright parts may. be performed at the same time or separately. When the shape of variable density patterns due to light and shade generated by unevenness is complicated, a transfer sheet capable of forming even complicated variable density patterns by printing is used to form the patterns by transfer.

摘要： PROBLEM TO BE SOLVED: To efficiently prepare a transfer product such as a decorative material with a three-dimensional uneven face. SOLUTION: A transfer layer side of a transfer sheet S consisting of a substrate and a transfer layer is faced to an uneven face side of a base material B to be transferred and solid particles P spouted from a spouting tool 5 are made to collide with the substrate side of the transfer sheet S. After the transfer sheet S is pressure-welded on the base material B to be transferred by the collision pressure, when the substrate is released to obtain a transfer product, the base material B to be transferred is placed on a base material placing stand 1 and the transfer sheet is fixed to a sheet fixing part 2 of the base material placing stand 1 positioned on the surroundings of the base material B to be transferred in such a way that the base material B to be transferred is separated from the surrounding space and is covered with the transfer sheet S and the base material placing stand 1. The collision pressure of the solid particles are applied thereby while it is suppressed that the solid particles turn round to the transfer layer side and the side of the base material B to be transferred.

摘要： PROBLEM TO BE SOLVED: To respond to high speed production by improving production efficiency by removing solid particles left on a support sheet rationally, surely, and promptly in a method and apparatus for transferring to an uneven backing in which the solid particles collide with the support sheet side of a transfer sheet and the transfer sheet is pressed evenly on the uneven surface of the backing. SOLUTION: When solid particles P left on a support sheet 1 are removed simultaneously with or after the delamination of the sheet 1, the delamination direction or the advance direction after delamination of the sheet 1 is changed to cross the preceding advance direction (at right angles), and the sheet 1 is turned upside down so that the solid particles P are removed by being dropped from the transfer passage of a backing B for transfer.

摘要： PROBLEM TO BE SOLVED: To obtain a grain pattern with a quality impression with no wiping by a method wherein an uneven surface is formed in a tracheal part embossed according to a woodgrain tracheal crosssectional pattern under the condition that the gloss of the uneven surface as just mentioned above is suppressed lower than that in the neighborhood of the tracheal part. SOLUTION: A resist pattern is formed at a tracheal part 1 by printing mapping image data outputted from an image file on a resist photosensitive layer applied onto the surface of an embossing cylinder 3 and then developing them. By peeling off the resist through etching, the tracheal part 1 is formed in an even shape according to a selected uneven pattern. The gloss of the uneven surface formed in the tracheal part embossed according to a woodgrain tracheal crosssectional pattern is suppressed to lower gloss. Thus, a realistic wood with the same quality impression as that of a decorative sheet, on which a wiping work is applied, can be reproduced.

摘要： PROBLEM TO BE SOLVED: To provide a decorative sheet with a high value added which has an added mixture of a glossy pattern showing a continuous gradation and a colored pattern showing a continuous gradation by wiping to a conventional printed pattern. SOLUTION: An embossing plate is manufactured which comprises an aggregation of independent projecting parts arranged in an offset or a gravure printing mode of halftone dots obtained by printing an endless halftone dot image with a continuous gradation on an embossing cylinder and eroding the printed image. The transparent thermoplastic sheet 2 side of a laminate made up a colored thermoplastic sheet 1 and the transparent thermoplastic sheet 2 between which a printing ink layer 3 forming a first image is sandwiched, is embossed using the embossing plate. Finally the glossy pattern showing a continuous gradation and a second image showing a continuous gradation are formed by a wiping action.

摘要： PROBLEM TO BE SOLVED: To efficiently manufacture a decorative material with a three- dimensional uneven face by transferring it up to the inside face of a recessed part. SOLUTION: The transfer layer side of a transfer sheet S made up of a support and a transfer layer is positioned opposite to the uneven face side of a base B to which a pattern is transferred, and a solid particle P jetted from an injector 1 is caused to run into the support side of the transfer sheet S. Further, the transfer sheet S is caused to come into contact with the base B under pressure by the impact pressure and a decorative material is obtained by peeling the support. In this case, the solid particle including that such as running obliquely into an enveloping surface E formed by the uneven surface of the base B is caused to collide with the transfer sheet S. Thus it is possible to tilt the base B with the horizontal plate or tilt the direction of the injector 1 obliquely with the vertical direction with the help of a base conveying device 2.

摘要： PROBLEM TO BE SOLVED: To efficiently manufacture a decorative material with a three- dimensional uneven face by securely transferring. SOLUTION: The transfer layer side of a transfer sheet S made up of a support 3 and a transfer layer 4 is positioned opposite to the uneven face of a base B to which a pattern is transferred, and a solid particle P jetted from an injector 1 is caused to run into the support side of the transfer sheet S. Further, after bringing the transfer sheet S into contact with the base B under pressure by the impact pressure, the support is peeled to obtain a decorative material D is this case, a net 5 is provided along the transfer sheet S near the support side of the transfer sheet S as a lifting control means, and the solid particle P is caused to run into the transfer sheet S through the opening part of the net 5. Thus it is possible to control a lifting phenomenon in which the transfer sheet S is separated from the base B and thereby prevent a pattern from becoming void or becoming creased as an inferior transfer due to the lifting phenomenon so that the transfer of the pattern is securely made.
