Patent ID: 7901863

Claim:
A laser engravable printing substrate comprising a photo-cured pattern-free product of a photosensitive resin composition, wherein the photosensitive resin composition comprises a resin (a) having a polymerizable unsaturated group having a number average molecular weight of 1000 or more and 200000 or less, an organic compound (b) having a polymerizable unsaturated group having a number average molecular weight of less than 1000, and an organic silicon compound (c) having at least one Si—O bond in a molecule and having no polymerizable unsaturated group in the molecule, and having at least one organic group selected from the group consisting of a methylstyryl group, a styryl group and a carbinol group, wherein a content of the organic silicon compound (c) is 0.1 wt % or more and 10 wt % or less based on the total amount of the photosensitive resin composition.
