    摘要: Presensitized printing plates are prepared by a process which comprises the steps of (1) coating a support with a radiationcurable composition, (2) placing a negative of the image to be printed on the coated support, (3) exposing the thus-formed system to radiation to effect polymerization of the exposed portion of the coating on the support and leaving the unexposed portion wet and uncured, (4) removing the negative, and (5) removing the uncured areas to produce an oleophilic image area and a hydrophilic non-image background. The radiation-curable composition comprises at least one isocyanate-modified polyethylenically unsaturated ester and at least one photoinitiator with optionally at least one polyethylenically unsaturated ester having free hydroxyl groups.
