ABSTRACT:
A sprayable pressure-sensitive adhesive mixture comprising a dispersion of a thermoplastic hydrocarbon derived resin having a softening point in the range of about 80.degree. C to about 110.degree. C derived from piperylene and 2-methyl-2-butene and a styrene-isoprene-styrene unvulcanized elastomeric block copolymer in a liquid dispersant selected from ketones and alcohols containing about 0 to about 5 weight percent alcohol. The sprayable adhesive mixture enables a method of applying a pressure-sensitive adhesive with attenuated cobwebbing which comprises applying an atomized spray coat under pressure of such an adhesive dispersion onto a substrate and drying the mixture.
