PROCESS FOR PREPARING COLOUR CONTRASTS ON ARTICLES OBTAINED BY MOLDING FROM POLYMERIZABLE COMPOSITIONS

摘要

Molding process of articles having colour contrast areas on the surface comprising the coating of the surface with a colored composition polymerized before filling the mold with a polymerizable fluid composition wherein the colored composition is a fluid, stable and redispersable dispersion, comprising: a) polymerizable liquid monomers, optionally in admixture with a non-polymerizable volatile organic solvent, as a solvent; b) from 0.1 to 10% by weight of a colouring composition as inorganic pigment or from 0.0001 to 1% by weight of a pigment or organic dye; c) from 1 to 30% by weight of an acrylic resin soluble in the solvent a) and containing reactive functional groups capable of giving crosslinking, the component a) being at least 20% by weight of the total composition.
