PURPOSE:To improve adhesiveness to metal, workability and preservable stability by incorporating a specific linear copolymer addition polymerizable compd. having >=100 deg.C b.p. under atm. pressure and photopolymerization initiator into a titled compsn. CONSTITUTION:This photosensitive material contains the linear copolymer having 2-30wt.% copolymerization rate of acrylic acid, 17-50mol.% content of carboxyl group, 4-30wt.% water absorptivity, and 3,000-400,000 weight average mol.wt., the addition polymerizable compd. having >=100 deg.C b.p. under the atm. pressure and the photopolymerization initiator. The compounding ratio of the addition polymerizable compd. is preferably 20-70pts.wt. per 100pts. wt. total of the linear polymer and the addition polymerizable compd. and the compounding ratio of the photopolymerization initiator is preferably 0.5-10.0 pts.wt. per 100pts.wt. total of the linear copolymer and the addition polymerizable compd. The adhesiveness to metal, workability and the preservable stability are thereby improved. |
