[Also in Division G2] A photographic process for the production of printing plates comprises image-wise exposing a photo-polymerizable material in the form of a plate or sheet and containing 80 to 40% by weight of a synthetic linear polyamide, 0À5 to 15% by weight based on the polyamide of benzene-sulphonic acid n-butylamide, 20-60% by weight of monomer(s) containing at least one monomer having at least two polymerizable double bonds and optionally at least one monomer with a single double bond, the single double-bond monomer content being up to 40% of the total monomer content, and a photo-initiator (e.g. benzoin methyl ether) and then developing the exposed material. A polymerization inhibitor may also be present in the composition of the layer. Exemplified monomers with at least two double bonds are alkylene and arylene bisacrylamides; 4,4<SP>1</SP>-bis-(acryloylamino cyclohexyl)-methane and triallyl cyanurate, while styrene, maleic anhydride, methyl methacrylate and butane diol-(1,4)-monoacrylate are exemplified as monomers with single double bonds. |
