Abstract
Petroleum resins having a softening point from 10.degree. C. to 80.degree. C. obtained from C.sub.5 olefines and diolefines and one or more monovinyl aromatic compounds contain from 10 to 30 wt. % of the aromatic are useful as tackifiers in a combination with carboxylated styrene butadiene copolymer to produce aqueous based pressure sensitive adhesives.
