PHOTOSENSITIVE COMPOSITION AND PHOTOSENSITIVE LITHOGRAPHIC PLATE

摘要

PURPOSE:To enhance sensitivity, to facilitate synthesis, and to stabilize quality by incorporating one of specified structural units in an acid-decomposable compound. CONSTITUTION:The photosensitive composition contains a compound capable of producing an acid on irradiation with acinic rays and the acid-decomposable compound having one structural unit represented by formula I in which X is C or H, and Y is C, and it may be same as or different from X. The use of the photosensitive composition thus obtained permits the lithographic plate provided with a photosensitive layer comprising it to have sensitivity high enough to be put to practical use.
