(assignment) Providing the polyimide resin composition which is excellent in applicability | paintability, favorable adhesiveness with various metal frames, high moisture resistance, and provides the hardened | cured material which exhibits low elasticity and high heat resistance. (Solution) (A) polyimide resin of the formula (1), {E is a group of Formula (2), F is a group of Formula (3), G is a divalent group derived from diamine. f + e + g = 100mol%, f / (e + g) mol ratio is 0.9 ~ 1.1, if the sum of e and g is 100, e is 30 ~ 90. (R A represents an arylenealkylene group, R 1 , R 2 represents a monovalent hydrocarbon group having no aliphatic unsaturated bond, R 3 , R 4 represents a monovalent hydrocarbon group, and either of R 3 and R 4 represents an aliphatic unsaturated bond) M is 0 ~ 20, n is 1 ~ 20, and m + n = 1 ~ 40.) (Im is selected from the group containing a cyclic imide structure at the end, X is selected from a single bond, -O-, -S-, etc.)} (B) hardener (C) solvent Silicone modified polyimide resin composition comprising a. |
