Abstract

An object is to obtain a pattern-transferred product excellent in fastness to washing. To achieve the object, the invention provides: a transfer film ( 10 ) including a transfer sheet ( 11 ) and a solvent UV ink layer ( 2 ) formed on the transfer sheet ( 11 ); and a transfer method including a hot-pressing step of sticking the transfer film ( 10 ) to the print object ( 20 ) and then hot-pressing the transfer film ( 10 ).

First claim

The invention claimed is:

1. A method for producing a transfer film, comprising:
providing a transfer sheet comprising a back surface and a front surface, wherein the back surface is opposite to the front surface, and an adhesive layer is formed on the front surface;
a forming step of forming a solvent UV ink layer on the back surface of the transfer sheet by an inkjet printing method;
a drying step of heating the solvent UV ink layer to volatilize a solvent in the solvent UV ink layer while maintaining a stickiness of the solvent UV ink layer;
a curing step of curing the solvent UV ink layer after the solvent has been volatilized by delivering thereon ultraviolet; and
a decorating step between the drying step and the curing step, wherein the decorating step is performed by adhering a decorative material on the solvent UV ink layer while maintaining the stickiness of the solvent UV ink layer or by forming a decorative layer containing a decorative material on the solvent UV ink layer while maintaining the stickiness of the solvent UV ink layer.

2. The method for producing a transfer film as claimed in claim 1 , wherein
in the drying step,
the solvent UV ink layer is preheated at a temperature between 40° C. and 60° C.,
the preheated solvent UV ink layer is heated at a temperature between 35° C. and 55° C., and
the heated solvent UV ink layer is post-heated at a temperature between 40° C. and 60° C.
