PURPOSE:To improve the photosensitivity of a titled compsn. by incorporating a compd. having specific orthonitrocarbinol ether groups into the compsn. CONSTITUTION:The compd. having >=1 orthonitrocarbinol ether groups which can be decomposed by projection of active rays, i.e., the compd. expressed by the formula is used in the compsn. In the formula, A denotes a nonmetallic atom group which forms an arom. ring or heterocycle with -C-C(-NO2)-; X denotes H, alkyl of 1-8C. This compd. is usable alone or in combination of >=2 kinds. A high mol.wt. binder (e.g.: novolak resin) which is insoluble in water and is soluble in an aq. alkaline soln. is preferably added to the compsn. A compd. which generates an acid by exposing and dye and lipophilic resins, etc., which bond to the acid may be added thereto at need. |
