Patent ID: 7029825

Claim:
A photosensitive resin composition for forming a laser engravable printing element, comprising: (a) 100 parts by weight of a resin which is a plastomer at 20° C., wherein said resin has a number average molecular weight of from 1,000 to 100,000 and has a polymerizable unsaturated group in an amount such that the average number of the polymerizable unsaturated group per molecule is at least 0.7, (b) 5 to 200 parts by weight, relative to 100 parts by weight of said resin (a), of an organic compound having a number average molecular weight of less than 1,000 and having at least one polymerizable unsaturated group per molecule, and (c) 1 to 100 parts by weight, relative to 100 parts by weight of said resin (a), of an inorganic porous material.
