Claim 2:
3. The composition according to claim 1, wherein the (meth)acrylic polymer further comprises one or more (meth)acrylic structural units selected from the following chemical formulae (2), (3) and (4):, , in which
radicals R1, R2 and R2′ are at each occurrence, identically or differently, as defined in claim 1;
R5 denotes, identically or differently at each occurrence, a straight-chain alkylene group having 1 to 20 C atoms, a branched alkylene group having 2 to 20 C atoms, an alkenylene or alkynylene group having 2 to 20 C atoms, or an arylene or heteroarylene group having 6 to 24 C atoms, where one or more methylene structural units (—CH2—) in said alkylene, alkenylene, alkynylene, arylene or heteroarylene groups may in each case be replaced by a sulfonyl group, a carbonyl group, an ether group, a sulfide group, a sulfoxide group, an ester group, an amide group, an imine group, a group CHR′ or a group CR′R″, wherein radicals R′ and R″ are as defined above; and
R6 denotes, identically or differently at each occurrence, a straight-chain alkyl group having 1 to 20 C atoms, a branched alkyl group having 3 to 20 C atoms, or a cyclic alkyl group having 3 to 20 C atoms.
