PURPOSE:To improve a gamma value by using the quinonediazide sulfonate of a polyhydric phenol compd. having a specific structure. CONSTITUTION:The gamma value can be improved by using an alkali-soluble resin and the quinonediazide sulfonate of the polyhydric phenol compd. expressed by formula I. In the formula I, Y1, Y2, Z1, Z2, Z3, Z4, Z5, Z6; C1 to C4 alkyl groups which may be substd. with halogen atom, a hydrogen atom or -OH group. Y1, Y2; At least one is a -OH group. Z1 to Z6; At least two are -OH group. R1 to R6; hydrogen atom, C1 to C10 alkyl group, C1 to C4 alkenyl group, cycloalkyl group or aryl group. |
