Patent ID: 7033676

Claim:
A binder mixture comprising (A) at least one polymer with a saturated main chain that is not polyester and (B) at least one polyester having a main chain that is saturated or unsaturated, wherein, (i) at least one of (A) and/or (B) has at least one of structural units I and/or II, in which the index n is an integer from 1 to 10; and with the provisos that (ii) when the polyester (B) has no structural units I or II, (B) comprises at least one of maleic esters and/or fumaric esters incorporated in its main chain, and (iii) when (A) contains no structural units I or II, (A) comprises covalently bonded photoinitiators of the Norrish II type as at least one of side groups and/or end groups, and wherein at least one of: (I) polymer (A) is a polyacrylate and comprises at least one copolymeric poly(meth)acrylate comprising in copolymerized form at least one (meth)acrylate monomer comprising at least one of structural unit I, structural unit II, further (meth)acrylic esters, and/or further olefinically unsaturated monomers copolymerizable therewith, and/or (II) components (A) and (B) are in a weight proportion of from 50:50 to 99.5:0.5.
