摘要 PURPOSE:To form an optional coloring pattern such as character and graphic pattern and the like, by coloring a polyester group resin layer provided on a magnetic layer with a sublimable coloring agent. CONSTITUTION:A magnetic layer 3a is coated on a polyester film 5a to form a heat sealing adhesive layer 7, obtaining a magnetic sticking sheet A. The plane of the adhesive layer 7 is stuck by overlapping it on an over-sheet 1. Then, it is pressed thermally on a core sheet 1a together with other over-sheet 1b. On the other hand, an ink including a sublimable coloring agent is used for a base sheet 8 to form a print pattern 9 such as character and graphic pattern and form a transfer sheet B, which is overlapped on the polyester film layer 5a, is heated and pressed, and the base sheet 8 of the transfer sheet B is exfoliated. The sublimable coloring agent in the print pattern 9 is transferred onto the polyester film layer in a card base to form a coloring pattern layer 6a.
