ABSTRACT:
In a method of producing a transfer film for providing pictures onto a molded product simultaneously with molding of the present invention, a resin which is dispersed in a dispersing medium to form a water-dispersed emulsion is coated on a substrate film made of a water-insoluble thermoplastic resin. Then the substrate film is dried until the coat solidifies to form a release layer. Further, a transfer layer which includes paint or ink diluted with an organic solvent for forming a desirable picture is formed on the release layer. Thereafter, the solvent is evaporated until the transfer layer turns to a solid film. Thus produced transfer film is used in the provision of pictures onto a molded product simultaneously with molding while insuring that the substrate film of the transfer film can be smoothly peeled from the picture or design layer after it is transferred to the shaped part without impairing the molding efficiency.
