A method of forming a photosetting film includes the steps of forming a photosensitive film containing (a) 100 parts by weight of a modified resin obtained by reacting an .alpha.,.beta.-unsaturated monocarboxylic acid derivative having an alcoholic hydroxyl group represented by formula: Image (I) (wherein each of R1 and R2 independently represents a hydrogen atom or methyl and R3 represents a hydrocarbon residue which may contain nitrogen or oxygen) with an .alpha.,.beta.-unsaturated dicarboxylic acid anhydride adduct having a softening point (measured by a ring and ball softening point method of JIS K2531-60) of not less than 70°C of a conjugated diene polymer or copolymer having a number-average molecular weight of 500 to 5,000, and a vinyl group content of not less than 50 mol% such that at least 10mol% of an acid anhydride group of the adduct are ring-opened, and (b) 0.01 to 20 parts by weight of a photoinitiator on a conductive substance and exposing the photosensitive film to active light.
