A photosensitive resin composition comprising compound (a) obtained by reacting a polybasic acid anhydride with phenolic hydroxyl of a novolac phenolic resin and 1,2-quinonediazide compound (b). A photosensitive resin composition satisfactorily excelling in photosensitivity, image contrast, resolution and adherence can be obtained by addition of the component of 1,2-quinonediazide compound (b) to the component (a) obtained by reacting a polybasic acid anhydride with phenolic hydroxyl of a novolac phenolic resin. |
