Abstract
Abstract 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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
116 words
A colored edible product comprising a translucent edible substrate having dissolved therein polymeric dye in a weight sufficient to yield a desired shade, said polymeric dye having a molecular weight of from about 2000 to 400,000 and consisting of one part by weight of chromophoric groups represented by Ch joined together by from 0.1 to 2 parts by weight of nonchromophoric linking groups represented by B into a structure represented by a structural formula selected from -- Ch B -- n and ##EQU2## wherein n is an integer greater than 1, said weight of polymeric dye being from about 0.4 to 0.9 times the weight of monomeric chromophoric groups Ch necessary to yield said desired shade.
Claim 2
Dependent Claim
116 words
A colored edible product comprising a translucent edible substrate having dissolved therein polymeric dye in a weight sufficient to yield a desired shade, said polymeric dye having a molecular weight of from about 2000 to 400,000 and consisting of one part by weight of chromophoric groups represented by Ch joined together by from 0.1 to 2 parts by weight of nonchromophoric linking groups represented by B into a structure represented by a structural formula selected from -- Ch B -- n and ##EQU2## wherein n is an integer greater than 1, said weight of polymeric dye being from about 0.4 to 0.9 times the weight of monomeric chromophoric groups Ch necessary to yield said desired shade.
Claim 3
Dependent Claim

Claim 5
Dependent Claim
11 words
The product of claim 3, wherein said substrate is a liquid.
Claim 6
Dependent Claim
11 words
The product of claim 3, wherein said substrate is a gel.
Claim 7
Dependent Claim
104 words
The process for coloring a translucent edible substrate to a desired shade which comprises dissolving in said edible substrate a weight of polymeric dye; said polymeric dye consisting of one part by weight chromphoric groups respresented by Ch, joined together by from 0.1 to 2 parts by weight of nonchromophoric linking groups represented by --B-- into a polymer represented by a structural formula selected from -- CH B -- n and ##EQU3## wherein n is an integer greater than 1, said weight of polymeric dye being from about 0.4 to 0.9 times the weight of monomeric chromophoric groups necessary to achieve said desired shade.
Claim 8
Dependent Claim
104 words
