A coating composition is provided in which the film-forming material consists of (a) 30-85% by volume of disperse phase particles of size 0.01-20 microns, of which not less than 50% are polymer microparticles, stably dispersed in (b) 70-15% by volume of a liquid continuous phase which is capable of

A coating composition is provided in which the film-forming material consists of (a) 30-85% by volume of disperse phase particles of size 0.01-20 microns, of which not less than 50% are polymer microparticles, stably dispersed in (b) 70-15% by volume of a liquid continuous phase which is capable of curing by a condensation polymerization reaction, the total volume of components (a) and (b) being 100% and the disperse phase being capable of taking part in the curing reaction. The composition can have a very high solids content and makes possible the production of thick films free from surface shrinkage.

A coating composition in which the film-forming material consists of: (a) from 30% to 85% by volume of disperse phase consisting of particles having a size or size distribution in the range 0.01-20 microns, not less than 50% by volume of those particles being polymer microparticles, and the disperse

A coating composition in which the film-forming material consists of: (a) from 30% to 85% by volume of disperse phase consisting of particles having a size or size distribution in the range 0.01-20 microns, not less than 50% by volume of those particles being polymer microparticles, and the disperse phase being in a state of stable dispersion in (b) from 70% to 15% by volume of a liquid continuous phase which is capable of curing to a film-forming polymeric material by means of a condensation polymerisation reaction, the said state of stable dispersion being a substantially de-floculated, sterically stabilised state achieved by means of a dispersing agent the molecule of which contains a polymeric component which is solvatable by the continuous phase liquid and another component which is relatively non-solvated thereby and is capable of associating with the surface of the microparticles, the total volume of components (a) and (b) being 100% and the disperse phase being capable of taking part in the said condensation polymerisation reaction.
