SELECTED O-QUINONEDIAZIDE SULFONIC ACID ESTERS OF PHENOLIC COMPOUNDS

摘要

The present invention relates to a photosensitive compound comprising at least one o-quinonediazide sulfonic acid ester of a phenolic compound having the following general formula (IB) or (IIB).;Wherein R ₁ , R ₂ , R ₁₁ and R ₁₂ are each independently hydrogen, OD, halogen, lower alkyl group of 1 to 4 carbon atoms, lower alkyl ether group of 1 to 4 carbon atoms and lower alkyl of 1 to 4 carbon atoms Thioether group, R ₃ , R ₄ , R ₅ , R ₆ , R ₇ , R ₈ , R ₉ , R ₁₀ , R ₁₃ and R ₁₄ are each independently hydrogen, halogen, lower alkyl group having 1 to 4 carbon atoms , A lower alkyl ether group having 1 to 4 carbon atoms and a lower alkyl thioether group having 1 to 4 carbon atoms, x and y are each independently an integer 0, 1, 2, 3 or 4, R _a , R _b , R _c And R _d are each independently selected from hydrogen and a lower alkyl group having 1 to 4 carbon atoms, v and w are each independently an integer 0 or 1, each sum of v and w on the fused ring is 1 or 2, A and B are each independently selected from the group consisting of oxygen, sulfur and methylene radicals, the OD group Each hydroxyl or o-quinonediazide sulfonic acid ester group, D is each selected from the group consisting of a naphthoquinonediazide sulfonyl group or a benzoquinonediazide sulfonyl group, provided that at least one -OD is an o-quinone Diazide sulfonic acid ester group.
