Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
90 words
A color proofing guide which comprises a transparent substrate having coated thereon a composition which is comprised of: (a) A light sensitive, high molecular weight diazo polymer having the formula: ##STR4## Wherein R is methyl or hydrogen X is methoxy, ethoxy or hydrogen Y is oxygen or sulfur Z is an anion of a sulfonic, carboxylic or phosphonic acid n is an integer from 8 to 970; and (b) an organic solvent soluble carrier resin; and (c) an organic solvent soluble dye which is non-reactant with the light sensitive polymer.
Claim 2
Dependent Claim
90 words
A color proofing guide which comprises a transparent substrate having coated thereon a composition which is comprised of: (a) A light sensitive, high molecular weight diazo polymer having the formula: ##STR4## Wherein R is methyl or hydrogen X is methoxy, ethoxy or hydrogen Y is oxygen or sulfur Z is an anion of a sulfonic, carboxylic or phosphonic acid n is an integer from 8 to 970; and (b) an organic solvent soluble carrier resin; and (c) an organic solvent soluble dye which is non-reactant with the light sensitive polymer.
