1. A primer comprising a mixture G which is dispersed or dissolved in one or more solvents and comprises:
at least one copolymer obtained by copolymerization of a monomer mixture comprising to an extent of at least 90 wt % the following monomers: vinylcaprolactam and/or vinylpyrrolidone and one or more of the monomers a) and/or b):
a) acrylic esters of a linear, primary alcohol having 2 to 10 carbon atoms in the alkyl radical of the alcohol,b) acrylic esters of a branched, noncyclic alcohol having 3 to 12 carbon atoms in the alkyl radical of the alcohol, at least one organofunctional silane of the general structure (I)
(R1O—)xSi(R2)y(R3)z (I), in which the radicals R1 independently of one another are a C1-C4 alkyl radical, a C2-C6 alkoxyalkyl radical or an acetyl radical; the radical R2 is an aminoalkyl radical, a vinyl group, a methacryloyloxyalkyl radical, an isocyanatoalkyl radical, an O-methylcarbamatoalkyl radical, a glycidyloxyalkyl radical or a phenyl radical; the radicals R3 independently of one another are a C1-C18 alkyl radical, and x=1, 2 or 3; y=0 or 1, and z=4−x−y; at least one metal compound selected from the group consisting of metal acetylacetonates, metal alkoxides, and alkoxy-metal acetylacetonates. |
