Field: Macromolecular chemistry, polymers (Chemistry)
Classification: CPC G  C | IPC C  G

Claim 0:
1. A radiation-curable mixture for generating relief structures, comprising
a) an ethylenically unsaturated compound as component A, said compound being a functionalized, part-hydrolyzed polyvinyl acetate comprising (i) vinyl alcohol units, (ii) vinyl acetate units, and (iii) vinyl acrylate units, where the vinyl acrylate units, which can be substituted, have the general structure, wherein the amount of vinyl acrylate units (iii) in the functionalized, part-hydrolyzed polyvinyl acetate a), based on all the units (i), (ii), and (iii), is 0.1 to <3 mol %, where R is hydrogen or a linear or branched aliphatic or heteroaliphatic radical, or a cycloaliphatic, heterocyclic or aromatic radical having up to 12 carbon atoms;
b) an initiator or initiator system as component B,
c) an ethylenically unsaturated compound different from component A, as component C,
d) an additive capable of hydrogen bonding, as component D,
said additive being present in an amount of 1 to 30 wt %, based on the sum of all components in the radiation-curable mixture;
wherein the additive capable of hydrogen bonding is selected from the group consisting of polyvinyl alcohol, polyvinyl acetate, polyethyleneimine, polyurethanes, polyethylene glycol, and polyvinyl alcohol/polyethylene glycol graft copolymer.
