ABSTRACT:
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.
