Abstract
A resin aqueous emulsion of a petroleum resin blend having a softening point of less than 85.degree. C. of a resin having a high softening point of at least 90.degree. C. and a resin having a low softening point is realized by utilizing from 3 to 10 parts by weight of an emulsifier consisting essentially of the class nonyl phenol alkoxylated with 10-12 moles of ethylene oxide per mole of nonyl phenol, anionic alkyl aryl sulfonate and mixtures thereof and dispersing a portion of the water as hot water in said blend prior to inversion into said emulsion.
