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 or of part of the surface of the mold 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) a solvent consisting essentially of polymerizable liquid monomers, optionally in admixture with a nonpolymerizable volatile organic 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 unsaturated polyester resin soluble in the solvent a), the component a) being at least 20% by weight of the total composition.
