COATINGS

摘要

The invention provides a base coat composition comprising a dispersion in an aqueous carrier for the composition of polymer microparticles, the polymer microparticles being a mixture of: (a) 5 to 95% by weight of addition polymer microparticles having a crosslinked core and a stabilising mantle containing salt forming groups and (b) 95 to 5% by weight of addition polymer microparticles having polyoxyalkylene stabiliser units derived from C1-4 alkoxypolyoxyalkylene containing monomers.
