LIGHT-SENSITIVE QUINONE DIAZIDE POLYMERS AND POLYMER COMPOSITIONS

摘要

Polyalkylene glycols end-capped with o-quinone diazide groups are a novel class of light-sensitive polymers which range from viscous liquid to waxy materials. The polymers can be used alone or in conjunction with other light-sensitive and nonlight-sensitive polymers to prepare light-sensitive coating compositions. Preparation of photoresists and printing plates using polymer compositions of this invention is described.
