Title:
PHOTOSENSITIVE RESIN COMPOSITION
Document Type and Number:
Japanese Patent JPH01306836
Kind Code:
A
Abstract:

PURPOSE: To improve the development property and the characteristics of molded goods of the title composition by using a polyester having a specified range of a high mol.wt., for the composition in a specified small amount, and solidifying the polyester with a large amount of an ethylenic unsated. compd.

CONSTITUTION: The composition is composed of 100pts.wt. of the ethylenic unsated. compd. having b.p. of ≥100°C, 10-50pts.wt. of the polyester which is soluble in the ethylenic unsatd. compd. and has a weight-average mol.wt. of 20000-300000 expressed in terms of polystyrene, and 0.01-10pts.wt. of a photopolymerization initiator as main components. At least 50wt% of a dicarboxylic acid component constituting the polyester is composed of a terephthalic acid component, and 40-70wt.% of a diole component is composed of a polyalkylene glycohol component selected from a polytetramethylene glycol, etc. Thus, a printing plate composed of a solidified photosensitive resin having the excellent moldability and development property, is obtd.
