Abstract

The invention addressed the problem of improving the adhesive strength of a dimensionally stable, soft-rubbing adhesive stick consisting of an aqueous preparation of a synthetic polymer and a soap gel as gel-forming component and, optionally, other auxiliaries. This problem was solved by the use of an at least substantially solvent-free aqueous polyurethane dispersion as the aqueous preparation of a synthetic polymer.
