<p>PROBLEM TO BE SOLVED: To provide a simple transfer film for curved surface printing, in which "loss of color" in the transfer is prevented even if water based dye ink is used.SOLUTION: The transfer film for curved surface printing is formed by laminating an image layer constituting a pattern printed from a dissolution layer side on a film comprising at least two layers of a layer (swollen layer) swelling with respect to a predetermined solvent and a layer (dissolution layer) dissolving in the predetermined solvent. The swollen layer is a polyvinyl alcohol, and has a saponification degree of 98.0-99.9 mol%, and an average polymerization degree of 500-4,000.</p> |
