Abstract:
1. A primerless pressure sensitive tape or label formed by a process comprising coating an aqueous PSA composition onto a release liner to form a coating, then drying the coating, and then passing the release liner, the coating, and a porous substrate material through a nip to transfer the coating to the porous substrate material, wherein said aqueous PSA composition comprises: i) 10 to 90 wt. %, based on the combined weight of parts (i) and (ii), of one or more aqueous adhesive (co)polymer, and ii) 10 to 90 wt. %, based on the combined weight of parts (i) and (ii), of one of more water-dispersed thermoplastic material, wherein the water-dispersed thermoplastic material is incompatible with the aqueous adhesive (co)polymer, and then drying said aqueous PSA composition.
