PURPOSE:To form a high density detailed image by low printing energy by using a sensitizer and a binder both of which have functional groups reacted and bonded each other. CONSTITUTION:A dye layer consisting of a dye, a binder and a sensitizer is provided on a base material film and the sensitizer and the binder have functional groups reacted and bonded each other. By forming the dye layer using the mutually reactive and bondable sensitizer and binder, a high density detailed image can be formed by low printing energy without generating a problem of preservability or fusion. As the binder resin for supporting the dye, a cellulose resin, a vinyl resin, an acrylic resin, a polyurethane resin, a polyamide resin or a polyester resin are designated. As the sensitizer, a thermoplastic resin oligomer, fatty acid, fatty acid amide or fatty acid ester are used. |
