Abstract
The invention relates to an adhesive for a floorcovering, comprising, based on the entire adhesive, from 5 to 30% by weight of at least one component selected from graphite and carbon black and/or from 0.2 to 3% by weight of conductive carbon fibers, from 25 to 50% by weight of a polyurethane dispersion with solids content of from 25 to 65% by weight, where less than 5% by weight of an aqueous dispersion of polyhydroxyether polymer, grafted with at least one acrylic or methacrylic monomer, with solids content of from 25 to 40% by weight, is present.
