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. |
