PROBLEM TO BE SOLVED: To obtain a light sensitive resin composition excellent in photocurable properties, and exhibiting homogeneous curability in the running direction of the light, and further to provide a method for producing the composition. SOLUTION: This light sensitive resin composition is obtained by reacting the carboxy group in an acrylic resin having a high light transmission, with an epoxy-containing acrylic unsaturated material, and having acrylic unsaturated bond. The light sensitive resin composition comprises the acrylic resin having the acrylic unsaturated double bond in the side chain, 5,000-200,000 weight average molecular weight, 3,000-50,000 number average molecular weight, 1.2-5.0 Mw/Mn and <=5 wt.% proportion of low molecular weight components having <=500 number average molecular weight. |
