Disclosed is a photosensitive resin which can be produced readily at a low cost, is easy to adjust its cross-linking density and acid value, and has excellent properties including high heat resistance, high transparency, a high refractive index and a low linear expansion coefficient. The photosensitive resin is produced by adding a (meth)acrylate compound having reactivity to a carboxylic acid and represented by general formula (2) to a polymeric compound, wherein the polymeric compound is produced by reacting a compound having a fluorene skeleton and represented by general formula (1) with a tetrabasic acid dianhydride. [In general formula (1), the rings Z1 and Z2 independently represent an aromatic hydrocarbon group; R1a and R1b independently represent a hydrogen atom or a substituent; R2a and R2b independently represent a substituent other than a hydrogen atom; R3a and R3b independently represent a hydrogen atom or a methyl group; k1 and k2 independently represent an integer of 0 to 4; m1 and m2 independently represent an integer of 0 to 3; n1 and n2 independently represent an integer of 0 to 10; and p1 and p2 independently represent an integer of 0 to 4.] [In general formula (2), R4 represents ahydrogen atom or a methyl group; and R5 represents a group represented by general formula (5).] [In general formula (5), q, r and s independently represent an integer of 0 to 9, provided that it is impossible that all of q, r and s represent 0 simultaneously.] |
