[PROBLEMS] To provide a dry transfer printing method for natural leather by a new dry transfer method that supports quality, cost, delivery and ecology. An ink containing an acid dye is printed or applied to a transfer paper to prepare a transfer paper, and the transfer paper is transferred by pressure and heat treatment in close contact with a natural leather material, followed by a dry heat treatment. A transfer paper used in a dry transfer printing method (fixing treatment), which is softened or melted by heating an organic solvent-soluble synthetic resin as a release agent layer and an ink receiving layer as an upper layer. A hydrophilic synthetic resin, a hydrophilic paste, and various auxiliaries are laminated in layers or in a mixed state. [Selection figure] None |
