PURPOSE:To enhance sensitivity, oil sensitivity, and developability by using a water-insoluble polymer having alcoholic hydroxyl groups and a water-insoluble diazo photosensitive material as main components. CONSTITUTION:Some of glycidyl esters or glycidyl ethers are additionally reacted with the phenolic hydroxyl groups of polyhydroxystyrene or its derivative, such as halogenated polyhydroxystyrene or nitrated polyhydroxystyrene to obtain a water-insoluble polymer having alcoholic hydroxyl groups on the side chains. This polymer and a water-insoluble diazo photosensitive material are used for the main components of a photosensitive compsn. |
