Organic pigment lakes are prepared by adsorption of a high molecular weight or polymeric dye onto suitable substratum or extender therefor. The properties of the resultant polymeric lakes approach those of true pigments, and said lakes exhibit maximized dye loading capacities and are exceptionally free of bleed. Thus, the applicability of lake colors is extended in the various food systems and their use is also permitted as industrial pigments.

Laked high molecular weight dyes

Viscoelastic materials are differently colored in zones with polymric dyes. When a polymeric dye is added to a zone of a viscoelastic material it does not migrate from the zone; thus permitting an essentially permanently multizoned colored product.

Zoned coloration

Translucent substrates such as foodstuffs are colored by adding polymeric dyes. The dyes contain from 0.1 to 2.0 parts of nonchromophoric material for each part by weight of chromophore and are added in a weight amount equivalent to from 0.4 to 0.9 times the weight of monomeric chromophore required to give the equivalent visual shade.

Coloring process and colored articles

Viscoelastic materials such as gelled food products are differently colored in zones with polymeric dyes. When a polymeric dye is added to a zone of a viscoelastic material, such as a gelled food product, it does not migrate from the zone; thus permitting an essentially permanently multizoned colored product.
