Abstract
Resins having a softening point from 10.degree. C. to 120.degree. C. especially 10.degree. C. to 80.degree. C. being a copolymer of a feed which is predominantly C.sub.5 olefines and diolefines and 10 to 60 wt. % of one or more monovinyl aromatic compounds are used as a tackifier for acrylic polymers or copolymers particularly in aqueous based pressure sensitive adhesives.
