A developer composition for use in developing after imagewise exposure of a photosensitive element member prepared by laminating a support, a layer of a photosensitive elastomer composition containing a diene polymer, and a transparent protective coating layer in order, which composition comprises 60-90 vol.% of at least one hydrocarbon selected from the group consisting of aliphatic and alicyclic hydrocarbons which are substantially free from double bonds, 5-30 vol.% of benzyl alcohol, and 1-10 vol.% of at least one compound selected from the group consisting of specified alcohols and acetates. When this developer is used for producing a photocuring image structure from the photosensitive element member, it is possible in general to remove a transparent protective coating layer comprising polyamide or cellulose completely in a short time together with an uncured part and to produce advantageously an excellent photocuring image structure, in particular a flexographic printing plate, wherein the photocuring image part swells little and is free from defects. |
