ABSTRACT:
The invention relates to an adhesive stick of an adhesive resin dissolved and/or dispersed in an aqueous solvent system and containing a gel-forming component and, if desired, other standard additives. The new adhesive stick is characterized in that its adhesive layers applied by rubbing onto a receiving surface show permanently tacky pressure-sensitive adhesive properties and in that the stick contains the reaction product of sorbitol and/or xylitol and benzaldehyde as the gel-forming component and, as adhesive resin, a reaction mixture from the reaction of methyl vinyl ether/maleic acid anhydride copolymers with partially neutralized acid phosphate esters of nonionic wetting agents of the lower alkylene oxide adduct type.
