PROBLEM TO BE SOLVED: To provide high printing ability and durability simultaneously by containing a polymer consisting of an oxazoline-containing polymer being cross- linked with a low molecular weight carbonic acid or a mercapto compound. SOLUTION: This contains a polymer consisting of an oxazoline-containing polymer being cross-linked with a low molecular weight carbonic acid or a mercapto compound. A method of manufacturing an oxazoline-containing polymer is not limited in particular; however, all well known copolymerization methods can be used which are melting polymerization, emulsion polymerization, suspension polymerization, bulk polymerization, and the like. By a reaction of an oxazoline group and carboxylic acid or thiol, the durability of a resin layer itself is obtained, and since such an oxazoline group itself is hydrophilic, and a produced cross-linking structure has an amide group that allows dye to be fixed easily, or cross-linking distances are relatively long, an ink absorptiveness is not hindered so much in comparison with other cross-linking structures.
