Title: RADIATION-CURABLE MIXTURE CONTAINING LOW-FUNCTIONALISED, PARTIALLY SAPONIFIED POLYVINYL ACETATE
Abstract:
The invention relates to a radiation-curable mixture for producing relief structures, containing a) at least one functionalised, partially saponified polyvinyl acetate containing (i) vinyl alcohol, (ii) vinyl acetate and (iii) vinyl acrylate units, wherein the vinyl acrylate units can be substituted and have the general structure (I), where R is hydrogen or a linear or branched aliphatic or heteroaliphatic radical having 1 to 12 C atoms or a cycloaliphatic, heterocyclic or aromatic radical having 3 to 12 C atoms, as component A, b) at least one initiator as component B, c) at least one ethylenically unsaturated compound which is different from component A as component C, d) one or more additives as component D, wherein the content of vinyl acrylate units (iii) of the functionalised, partially saponified polyvinyl acetate a) is 0.1 to < 3 mol% in relation to all the units (i), (ii) and (iii), and component D contains an additive which can form hydrogen bonds in an amount of 0.001 to 30 wt% in relation to the total of components A to D.
