PURPOSE:To improve a working environment, to prevent air pollution, and to reduce swelling of the cured elastomer composition by using an organic solvent obtained by mixing a specified ester and a specified alcohol in a specified ratio. CONSTITUTION:The photosensitive elastomer composition is developed by using a mixture of a compound represented by formula I in a volume ratio of 100/0 - 40/60 as an image forming developer. In formula I, R<1> is methyl or ethyl, and R<2> is an aralkyl group represented by -CnH2nAr, Ar being an aryl group, (n) being 0, 1, or 2, an alkoxyalkyl group represented by -CnH2nOCmH2m+1, n + m <= 5, n >= 1, m >= 1, or the like. In formula II, R<3> is an alkyl group represented by -CnH2n+1, n = 3 - 10, or aralkyl represented by -CnH2nAr, n = 1 - 3, thus permitting the working environment to be improved, air pollution to be prevented, and swelling of the hardened photosensitive elastomer to be lowered. |
