Abstract: The invention relates to a primer, comprising a mixture dissolved or dispersed in one or more solvents, the mixture composed of a copolymer obtained through copolymerization, preferably free-radical copolymerization, of vinylcaprolactam and/or vinylpyrrolidone, and one or more of the following monomers: a) an acrylic acid ester of a linear primary alcohol containing 2 to 10 carbon atoms in the alkyl group of the alcohol, b) an acrylic acid ester of a branched, non-cyclic alcohol having 4 to 12 carbon atoms in the alkyl group of the alcohol, and c) acrylic acid; one or more organofunctional silanes; a dye or a pigment based on a metal complex or a metal oxide, wherein the metal oxide is of a spinel-type. Such primer provide reliable and excellent adhesion between pressure-sensitive adhesive tapes and hydrophilic surfaces, in particular glass, and ensures at the same time a good coloration of the primer, thereby producing an opaque primer layer.

Abstract: In the case of a liner for the protection of adhesives, the protective effect is to be enhanced in respect of permeates originating from the environment and also permeates included during winding or stacking and other processing steps. This enhancement is accomplished through provision of a liner which comprises at least one adhesive release layer and at least one layer of a getter material capable of sorbing at least one permeable substance.
