Class Information
Number: 430/182
Name: Radiation imagery chemistry: process, composition, or product thereof > Diazo reproduction, process, composition, or product > Composition or product which contains radiation sensitive compound having moiety of nitrogen double or triple bonded directly to nitrogen other than chromophore moiety, e.g., triazene containing product, etc., process of making, and composition or product used to finish or develop a diazo reproduction > Radiation-sensitive composition > Diazonium compound containing > Aceto-aceto or heterocyclic coupler included
Description: Compositions which additionally contain a compound, having an active methylene group between two carbonyl groups or a heterocyclic residue, which functions as a coupler for dye formation. Examples of the former are acetoacetanilide and cyclohexylacetoacetic acid amine, and of the latter are pyrazolones, hydroxy pyridones and thiobarbituric acid.
