Abstract

The present invention is directed to a novel adhesive which is a mixture of PA1 A) at least one aqueous dispersion of a polymer which has a softening point below 70.degree. C., said dispersion containing 5 to 70% by weight solids and having a film-forming temperature below 70.degree. C., and PA1 B) at least one aqueous dispersion of a polymer based on olefinically unsaturated monomers having a softening point is above 70.degree. C., said dispersion containing 5 to 70% by weight solids, PA1 wherein the weight ratio of dispersion A) to dispersion B) is from 97:3 to 60:40, based on the solids content of said dispersions.
