ABSTRACT:
When a water-soluble alcohol having 4 to 6 hydroxyl groups is added to a photosensitive composition comprising a water-soluble polymer substance and a bisazide crosslinking agent, the polymer crosslinking reaction by said bisazide crosslinking agent is promoted and a polymer crosslinkage enough to form an image is produced even at a low exposure dose of ultraviolet ray. Thus, the photosensitive composition is highly sensitized as compared with prior art photosensitive compositions. The alcohol is exemplified by erythritol, pentitol, etc. and is preferably added in an amount of 1 - 100 parts by weight per 100 parts by weight of the water-soluble polymer substance.
