ABSTRACT:
The present invention relates to a photocurable resin composition, wherein the composition comprises:(A) a polyimide resin having one or more primary alcoholic groups with an alcoholic equivalent equal to or less than 3500, said polyimide being soluble in an organic solvent and having a weight average molecular weight of from 5,000 to 500,000; (B) at least one selected from the group consisting of a condensate of an amino compound modified with formalin, optionally further with alcohol, preferably a melamine resin modified with formalin, optionally further with alcohol, and a urea resin with formalin, optionally further with alcohol, and a phenolic compound having, on average, at least two selected from the group consisting of a methylol group and an alkoxy methylol group, and (C) a photoacid generator capable of generating an acid upon irradiation with light of a wavelength of from 240 nm to 500 nm.
