Abstract
A photosensitive resin composition comprising a polymeric binder, an ethylenically unsaturated monomer and a photopolymerization initiator is disclosed. Also, a PS plate using the same is disclosed. The photopolymerization initiator comprises at least one compound selected from specific triazine compounds having a bromine atom on the substituted phenyl nucleus thereof and specific trihalomethyl-containing triazine compounds. The composition has high photosensitivity sufficient for exposure with an argon laser light and satisfactory developability. Additionally disclosed is a photosensitive resin composition comprising a polymeric binder, a monomer having an ethylenically unsaturated double bond and photopolymerization initiators including an acridine compound and a specific triazine compound. This second photosensitive resin composition has high sensitivity, high resolution and a wide development margin. Using this photosensitive resin composition, color filters and PS plates can be produced that have high sensitivity and resolution even to low-energy visible light and which assure high pattern reproducibility.
