Abstract
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.
Claims6
A multicolored composition comprising a plurality of zones of viscoelastic edible substance, said zones containing different effective coloring amounts of polymeric dye of a molecular weight of from 2000 to 400,000, said dye being represented by the structural formula selected from the formulae --(Ch B).sub.n
- and ##EQU3## wherein n is an integer greater than 1, Ch is an organic chromophore and B is a non-chromophoric organic linking group, and said zones thereby differing in color from one another.
