Claim Text:
1. A process of solvent-free emulsion comprising: a) heating at least one high viscosity resin to a temperature of about 90° C. or higher to form a heated resin in a reaction vessel comprising a mixing device; wherein the high viscosity resin comprises a resin having a melt viscosity of from about 10 to about 1,000,000 Pa*S at about 130° C.; b) combining the heated resin with a surfactant and a neutralization agent in the absence of an organic solvent to form a mixture in said reaction vessel; c) increasing pressure in said vessel to from about 10 to about 1000 kPa; d) adding water to said mixture to form an emulsion under agitation; and e) reducing pressure in said vessel to obtain a solvent-free emulsion comprising resin particles.
