摘要：
A positive type colored photosensitive resin composition containing an alkali-soluble copolymer resin which comprises repeating units derived from styrene and repeating units derived from hydroxystyrene, a ratio (molar ratio) of the latter repeating units to the former repeating units is from 1:0.7 to 1:20 and has a polystyrene-converted weight average molecular weight of 6,000 to 15,000.
