Abstract
A process for forming a coating on a surface of a substrate which comprises; (i) applying a layer of a composition comprising a polymer phase, in which the polymer phase comprises a crystallisable polymer selected from polyesters, polyamides, and polycarbonates, in intimate admixture with a non-curable solvent for the crystallisable polymer, and, (ii) heating the applied layer to a temperature at least high enough to cause film formation.

A process for forming a coating on a surface of a substrate which comprises:
- (i) applying a layer of composition comprising a polymer phase in dispersion in a non-aqueous continuous diluent, in which the polymer phase comprises an effective film-forming amount of a crystallisable polymer, selected from polyesters, polyamides, and polycarbonates, in intimate admixture with a non-crosslinkable solvent for the crystallisable polymer, said polymer phase and diluent being immiscible so as to provide the dispersion thereof and an effective amount of a stabilizer sufficient to maintain the polymer phase dispersed in the diluent and
- (ii) heating the applied layer to a temperature at least high enough to cause film formation.
