Abstract
Official abstract text for this publication.
The invention relates to an aqueous adhesive composition containing at least one acrylate polymer with a glass transition temperature Tg>50° C. and at least one amorphous polyurethane or polyurethane-polyurea polymer with a glass transition temperature Tg<+10° C., the use of the adhesive compositions for the manufacture of heat-activated adhesive layers, and planar formations containing adhesive layers based on the adhesive composition.
First claim
Opening claim text (preview).
The invention claimed is: 1. An aqueous adhesive composition comprising at least one acrylate polymer with a glass transition temperature in the range from 50° C. to 90° C. and at least one amorphous polyurethane or polyurethane-polyurea polymer with a glass transition temperature in the range from −50° C. to 10° C., the glass transition temperature being determined by a DSC measurement according to DIN 65467 at a heating rate of 20 K/min, wherein a dry film obtained from the aqueo…
