PURPOSE: To enhance scratch resistance of an ink-repelling layer and folding and printing resistance of the printing plate by specifying the tensile strength and the Vickers hardness of a primer layer. n CONSTITUTION: The printing plate is formed by successively laminating on a substrate the primer layer containing (A) an ethylenically unsaturated compound having a polymerizable unsaturated group, such as polyol (meth)acrylate or an unsaturated monomer having a urethane group, and (B) a photopolymerization initiator, such as benzoin derivatives or thioxananthone derivatives, and having a tensile strength of ≥ 10 kg/cm 2 and a Vickers hardness of ≤ 70, a photosensitive layer, and the ink-repelling layer. n COPYRIGHT: (C)1992,JPO&Japio |
