A solvent-free polysiloxane-modified polyimide resin composition is a polysiloxane-modified polyimide resin containing (A) formula (1), Ee-Ff-Gg (1) (E is formula (2), F is the formula (3), G is the divalent residue produced by diamine. f+e+g=100mol%, the mol ratio of F/(e+g) is 0.8~1.2) (R A is a divalent hydrocarbon group of, R 1 ~ R 4 is the monovalent hydrocarbon group, R 5, R 6 is alkyl, aryl or aralkyl group .m, n, o is 0 ~ 20, n + o ≧ 1. m+n+o=1~60)-Im-X-Im- (3)(Im is a cyclic group containing a cyclic imine structure, X is a single bond, oxygen, sulfur, thioether group , Sulfonyl group, carbonyl group, -NR N - , -CR B 2 -, -R Ar h -, -R Ar h (OR Ar ) i -, alkylene group, trivalent derived from the dissociation of 1 H from this group (B) polymerizable compound, (C) polymerization initiator, (D) hydrophobic fumed silica. And it has fluidity and does not contain solvents.n n n The composition of the present invention has excellent operability due to its fluidity, thixotrophy and the like. |
