ABSTRACT:
A process for producing a dyed article having a substrate laminated with a fluororesin film comprises the steps of: providing a substrate having laminated thereon a fluororesin film through an adhesive layer; contacting an original having a pattern or image formed with a sublimating or volatile dye with a surface of said fluororesin film opposite to said adhesive layer; heating said original to allow said dye to permeate said fluororesin film; and allowing said dye to be trapped by at least one of said adhesive layer and said substrate to transfer the pattern or image of the original thereto. According to the process, designs of an original can faithfully be transferred to a substrate for dyeing having any desired substrate on which a fluororesin film having high resistances to light, solvents, heat and stains is laminated.
