(A) a structural unit derived from a polymerizable unsaturated compound having an acid group (a-1), a structural unit represented by the following formula (1) or (2) (a-2), and a structural unit derived from another polymerizable unsaturated compound ( As a copolymer containing a-3), when the total of all structural units is 100 mol%, 20 mol% to 80 mol% of the structural unit (a-2) is included, the weight average molecular weight is 1000 to 50000, and a copolymer having a molecular weight distribution (Mw/Mn) of 1.5 to 3.0; (B) a solvent containing at least one selected from the group consisting of primary alcohols having 3 to 10 carbon atoms and secondary alcohols having 3 to 10 carbon atoms; (C) a reactive diluent; (D) A photoinitiator is included, The photosensitive resin composition characterized by the above-mentioned. [In Formula (1), R< 1> represents a hydrogen atom or a methyl group, and n is an integer of 1-10. In formula (2), R 2 represents a hydrogen atom or a methyl group, and m is an integer of 1 to 10.] |
