More Information
Summary:A crosslinkable, especially photopolymerizable urethane resin soluble in organic solvent, suitable as starting materials for photoresist lacquers and for the production of photopolymer printing plates comprising a reaction product of a polyepoxide having more than one 1,2-epoxide group per molecule with acrylic and/or methacrylic acid so that from 60 to 100 mole % of the 1,2-epoxide groups are converted into beta -hydroxy acrylic or methacrylic ester groups; 30 to 90 mole % of said beta -hydroxy ester groups having been reacted with an isocyanate and subsequently 10 to 70 mole % of said beta -hydroxy ester groups having been converted into acid semiester groups with a cyclic dicarboxylic acid anhydride.
