FORMING PROCESS OF FLUORESCENT LATENT IMAGE

摘要

PROBLEM TO BE SOLVED: To provide a forming process of a fluorescent latent image excellent in transferability and tone property.

SOLUTION: This is the forming process of the fluorescent latent image where a fluorescent latent image transfer film 1 with a fluorescent ink layer 3, made from resin binder of vinyl polymers as a principal component and containing a specific bisbenzoxazolyl fluorescence agent and being placed over on top of the transfer surface of heat-resistant substrate film 2, is piled up so that the transfer surface of the fluorescent latent image transfer film 1 contacts to an image forming face of the object to be transferred and then the fluorescent latent image transfer film 1 is heated up from its back side by the heater along with the pre determined pattern and thus transfers the patterns to the image forming face by sublimation transfer manner.
