PURPOSE:To obtain the titled composition having an improved adhesive property to metal by adding a specified 2-substituted-4,6-dithiol-S-triazine deriv. to a photosensitive resin. CONSTITUTION:To a photosensitive composition consisting of a photosensitive resin, an org. binder such as polyvinyl chloride, and a photopolymn. initiator such as anthraquinone is added 0.1-10wt% 2-substituted-4,6-dithiol-S-triazine deriv. represented by the formula [where R1 is SR2 or R2; each of R2 and R3 is H, -NHR or -N(R2); and R is H, hydroxyl, alkyl, phenyl, benzyl, naphthyl, cyclohexyl, alkoxyl or phenoxyl]. Said photosensitive resin is made from a nongaseous ethylenic unsatd. compound having two or more terminal ethylene groups and >=100 deg.C b.p. under atmospheric pressure, e.g., 2-hydroxyethyl methacrylate. |
