ABSTRACT:
Pressure-sensitive adhesive compositions having an improved set of physical properties especially at elevated temperatures yet having low melt viscosity and thus capable of being applied by means of a wipe-off coater comprise certain block copolymers, resins compatible with a rubbery phase of said copolymers, extender oil and resins compatible with the plastic blocks having softening points higher than those of the plastic polymer blocks of the copolymer.
