Process for preparing color contrasts on articles obtained by molding from polymerizable compositions

摘要

Molding process of articles having color 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 non-polymerizable volatile organic solvent; b) from 0.1 to 10% by weight of a color composition as inorganic pigment or from 0.0001 to 1% by weight of an organic 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.
