Abstract:
A photosensitive resin composition comprising:a copolymer resin; a bifunctional or higher polyfunctional photopolymerizable acrylate monomer; an epoxy resin; and an initiator, said copolymer resin comprising 5 to 55% by mole of constituent units represented by formula (1) and 5 to 95% by mole of constituent units represented by formula (2), the constituent units represented by formula (1) having been partially reacted, through carboxyl groups thereof, with a (meth)acryloylalkyl isocyanate compound, the constituent units represented by formula (2) having been partially reacted, through hydroxyl groups thereof, with a (meth)acryloylalkyl isocyanate compound, said copolymer resin containing 5 to 95% by mole of (meth)acryloyl groups and having an acid value of 5 to 400 mg KOH/g and a weight average molecular weight of 10,000 to 1,000,000 as determined using polystyrene as a standard: â€ƒwherein R represents hydrogen or an alkyl group having 1 to 5 carbon atoms and R1 represents an alkylene group having 2 to 4 carbon atoms, and 5 to 50% by mole of constituent units represented by formula (3) and 0 to 75% by mole of constituent units represented by formula (4): â€ƒwherein R represents hydrogen or an alkyl group having 1 to 5 carbon atoms, R2 represents an aromatic carbon ring, and R3 represents an alkyl group or an aralkyl group.
