EMULSIFIABLE RESIN COMPOSITIONS Abstract of the Disclosure Disclosed are resin compositions which are solids at room temperature (about 23°C), are storage stable, can be easily and readily handled, do not tend to freeze in storage during cold weather, and contain from about 2% to no greater than 13% water. The compositions consist essentially of, by weight, (1) from about 82% to about 95% of a resin or resin blend having a viscosity of greater than 100,000 centipoise at 60°C and a Ring & Ball softening point greater than 60°C, such as an ester of rosin, and an aliphatic hydrocarbon resin prepared by polymerizing monomer mixtures formed by cracking petroleum hydrocarbon mixtures; (2) from about 3% to about 5% of at least one anionic emulsifying agent; and (3) from 20 to 60 moles of water per mole of anionic emulsifying agent. These solid compositions can be easily and readily dispersed in an aqueous media to provide aqueous dispersions which are useful in the manufacture of water-borne adhesives.
