PURPOSE: To eliminate any damage due to swelling at the time of performing development by adding a specific aldehyde compound to a mixture containing a polymer contg. hydroxyl groups or the like, a photopolymerizable monomer and a photopolymerization initiator thereby obtaining a photopolymerizable resin composition. CONSTITUTION: In this composition, as a polymer contg. hydroxyl or amino groups, a polyamide, polyvinyl alcohol, or the like is used, and as a photopolymerizable monomer, an acrylate or the like is used. Also, an aldehyde compound represented by the formula is added to the mixture containing the polymer, the photopolymerizable monomer and a photopolymerization initiator in an amount sufficient by a 0.1 to 10wt.% of the aldehyde compound obtain the photopolymerizable resin composition. In the formula, R is H or an alkyl, aryl, or aryloxy group. As the aldehyde compound, glyoxal or glyoxylic acid is exemplified. This resin composition is irradiated with light to subject it to photopolymerization and corsslinking. Accordingly, since a photosensitive recording material is obtained by applying the resin composition, a printing plate having high quality without causing any damage due to swelling at the time of performing development using an aqueous medium can be obtained.
