(57) [Abstract] [Purpose] A novel positive mold for producing a relief structure capable of being developed using an alkaline aqueous solution and capable of producing a layer which is sensitive to UV light of a short wavelength. To provide a highly radiation sensitive system. A radiation-sensitive mixture essentially consisting of (a) a binder or a mixture of binders which is insoluble in water and (b) a compound which forms a strong acid upon irradiation, comprising component (a) Is a phenolic resin, and some or all of the phenolic hydroxyl groups of the phenolic resin are groups (IA) or (IB) embedded image [Wherein R 1 , R 2 and R 3 each represent alkyl, or R 1 together with R 2 forms a ring, X is CH 2 , O, S, SO 2 or NR 4 ]. This mixture is suitable for producing relief structures. |
