摘要: Aqueous dispersions containA) from 20 to 90% by weight of a dispersed polymer having a glass transition temperature above 30.degree. C. andB) from 10 to 80% by weight of a tri-, tetra-, penta-or hexa(meth)acrylate of an alkoxylated, trivalent to hexavalent alcohol having a mean degree of alkoxylation of the hydroxyl groups of the alcohol, defined as the quotient of the number of alkoxy groups to the number of hydroxyl groups, ie. the functionality of the alcohol prior to the alkoxylation, of at least 0.5,the stated weights being based on the sum of A) and B).
