Abstract
PURPOSE:To improve the shelf stability of the titled composition by controlling a specified impurity contg. in the titled composition contg. a four functional quinone diazide type photosensitive compd. to less than a prescribed amount. CONSTITUTION:The titled composition comprises the component of the quinone diazide type photosensitive compd. in which the peak area of said compd. having 0.75-0.9 times retention time against that of the peak of a quinone diazide compd. composed of sulfonates formed by substituting the all four hydroxy groups of tetrahydroxy benzophenone, is <=3% the total peak area in a liquid chromatographic analysis. In said liquid chromatographic analysis, a porous silica gel which is allowed to chemically bond with octadecylsilane, is merely used for a column, and a mixture of acetonitrile, water and acetic acid is used for an elute. Thus, the deterioration of the application property of the titled composition can be prevented after storage for a long period.
