Abstract

Floor covering adhesives substantially comprising PA0 A. a dispersion of a copolymer of PA1 20-60% by weight of vinylidene chloride PA1 34-80% by weight of a mixture of 40-80 parts by weight of esters of acrylic acid with C.sub.1 -C.sub.18 -alkanols and 20-60 parts by weight of vinyl esters and PA1 0.5 to 6% by weight of .alpha.,62 -monoolefinically unsaturated C.sub.3 -C.sub.5 -mono- and/or dicarboxylic acids and/or amides thereof and/or vinyl sulfonate, PA0 B. 30-150 parts by weight (solid), based on 100 parts of a copolymer of A, of tackifying resins from the group of the rosins and derivatives thereof, PA0 C. 0-50 parts by weight, based on 100 parts of resin B, of plasticizers and/or liquid resins and also, if desired, PA0 D. fillers, are shampoo-resistant and have a high peel strength.
