ABSTRACT:
Aqueous dispersions of copolymers having a glass transition temperature of not more than -45.degree. C. and a K value greater than 80 consist of not less than 80% by weight of acrylates of alkanols of 8 to 12 carbon atoms, from 1 to 4% by weight of .alpha.,.beta.- monoolefinically unsaturated carboxylic acids and/or their amide derivatives and from 0.1 to 3% by weight of .alpha.-methylstyrene, and are used for the production of self-adhesive structures having good tack at as low as -40.degree. C.
