Abstract (en)
[origin: WO2015169575A1] The invention concerns a primer comprising a mixture G, in dispersion or solution in one or more solvents, of at least one copolymer obtained by copolymerizing a monomer mixture comprising at least 90 wt% of the following monomers: vinylcaprolactam and/or vinylpyrrolidone and one or more of 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 non-cyclic 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, 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 glycidoxyalkyl 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. A primer of this kind enables effective promotion of adhesion between pressure-sensitive adhesive tapes and hydrophilic surfaces like glass especially, and allows for incorporation of functional fillers.
