PHOTOSENSITIVE RESIN COMPOSITION

摘要

A photosensitive resin composition containing at least thermoplastic elastomer (a), photopolymerizable unsaturated monomer (b) and photopolymerization initiator (c), characterized in that the thermoplastic elastomer (a) contains at least a vinyl aromatic hydrocarbon unit, a butadiene unit and an alkylene unit, the alkylene unit amounting to 5 to 80 wt.% based on the total amount of butadiene unit and alkylene unit. This photosensitive resin composition simultaneously satisfies the requirement of excellent fine line reproducibility, resistance to ester solvents and printing surface cracking prevention.
