Abstract
An aqueous solid particle dispersion of a thermal solvent, where said thermal solvent is a water-immiscible phenol derivative and has a melting point, T.sub.m, between 30.degree. C. and about 200.degree. C., wherein said dispersion contains a dispersing aid, and wherein the thermal solvent particles in said dispersion are essentially nanocrystalline is disclosed. Also disclosed is a process for forming a coating comprising the steps of: PA1 providing an aqueous solid particle dispersion of thermal solvent, where said thermal solvent is a water-immiscible phenol derivative and has a melting point, T.sub.m, between 30.degree. C. and about 200.degree. C., and where said dispersion contains a dispersing aid; PA1 combining said aqueous solid particle thermal solvent dispersion with a coating melt composition, where said coating melt composition is maintained at a temperature, T.sub.c, during the preparation and coating of said coating melt composition, and where T.sub.c <T.sub.m ; PA1 coating said coating melt composition onto a support to form a coating; PA1 drying said coating by means wherein the temperature of said coating is maintained less than T.sub.m.
