47 ABSTRACT OF THE DISCLOSURE A photopolymerizable or radiation polymerizable alkaline developing crosslinking curable resin composition possessing superior antiplating properties and a short stripping period, in which the stripped plate is not easily dissolved in the stripping fluid, and which is comprising: (a) 5-30 parts by weight of at least one compound possessing in one molecule on the average 1.5 or more (meth)acryloyloxy groups, which is obtained by reacting (meth)acrylic acid with a reaction product formed by adding, to a polyatomic alcohol possessing 3 or more OH groups in one molecule, an alkylene oxide containing propylene oxide in an amount of 67% molar or greater in an amount of 5-12 moles per mole of OH group in the aforementioned polyatomic alcohol, (b) 5-30 parts by weight of at least one crosslinkable monomer other than that stated above in (a), possessing in one molecule 2 or more ethylenically unsaturated groups, (c) 45-75 parts by weight of a thermoplastic polymer for use as a binder, the thermoplastic polymer in turn being formed of 15-35 wt % of at least one .alpha.,.beta.-unsaturated carboxyl group containing a monomer having 3-15 carbon atoms, and 65-85 wt % of another copolymerizable monomer, and (d) 0-10 parts by weight of a photopolymerization initiator.
