Abstract

The invention relates to a process for producing anisotropic pressure-sensitive adhesives (PSAs) using conventional coating methods. It is envisaged that a PSA film be produced on a transport carrier and that it then be transferred to a further carrier material with simultaneous stretching, the elongation being as least 10%.
