DEFINITION

Classification: 430/190

Polymeric quinone diazide:

(under subclass 189) Compositions wherein the quinone diazide moiety is an integral part of a polymer such as when the moiety is appended to a polymeric backbone with linking sulfonamide groups as in the reaction product of a p-aminostyrene polymer and an o-quinone diazide sulfonic acid.
