PROBLEM TO BE SOLVED: To obtain a photosensitive resin composition having a fast ink absorption rate, excellent waterproofness, a sharp ink dot shape and excellent ink color developability by incorporating an N-alkoxymethyl(meth)acrylamide, a photopolymerization initiator and a polymer as essential components. SOLUTION: An N-methoxymethyl(meth)acrylamide or an N-ethoxymethyl(meth)acrylamide can be solely or combinedly used. They are used to raise printability, dryability and waterproofness of an ink for an ink jet to an ink receptive layer. As a photopolymerization initiator, 2-hydroxy-2- methylpropiophenon or the like is used. The photosensitive resin composition contains a polymer as an essential component, and desirably contains a hydrophilic polymer. As the composition, a modified polyvinyl acetate or the like is used, and has excellent ink fixability, waterproofness. The composition is effective as an ink receptive layer of a medium to be recorded of an ink jet recording type, and optimum for printing an optical disk. |
