摘要： A photopolymer intaglio printing plate comprising a support member and a photopolymer layer provided thereon, said layer having concave portions of a constant depth as ink cells and the lowermost part of each of the concave portions reaching to the surface of the support member so that the surface of the support member is exposed to air at least as a point at said lowermost part, prepared by subjecting a photosensitive plate comprising the support member and a layer of a photopolymerizable composition provided thereon to exposure through a halftone negative or positive film to such an extent that the photopolymerizable composition at the exposed parts is cured down to the bottom of the photopolymerizable composition layer but the photopolymerizable composition at the non-exposed part having a minimum area remains uncured at the lowermost part corresponding to the center of the said non-exposed part and washing out completely the photopolymerizable composition at the non-exposed parts.

摘要： A process for formation of a relief image which comprises exposing a layer of a photosensitive composition in liquid provided on the surface of a support material to light through a negative to make cured the photosensitive composition at the exposed part and eliminating the non-cured photosensitive composition at the non-exposed part by suctioning for development, the photosensitive composition comprising as the essential components only (1) at least one addition polymerizable unsaturated monomer having at least one acryloyl or methacryloyl group per each molecule and a molecular weight of not more than about 1000 per each acryloyl or methacryloyl group and (2) at least one photopolymerization initiator.
