Abstract
PURPOSE: To provide a maleimide compound with a fluidity, thereby improving its workability, and an improved crack resistance without injuring its thermal resistance, by blending the maleimide compound with a spiroacetal compound having a double bond.
CONSTITUTION: The object resin composition is prepared by mixing (A) 100pts. maleimide compound of a low m.p. (e.g., formula I), (B) approx. 0W70pts. N, N'-substd. bismaleimide compound (e.g., N, N'-diphenylmethanebismaleimide or N, N'-m-phenylenebismaleimide) and (C) approx. 0W200pts. spiroacetal compound having a double bond (e.g., formula I) or its prepolymer (e.g., formula III, where R is H or CH3). This composition has a long pot life and can be used not only as solventless varnish but also as solvent-sensitive varnish, and a hardened resin thereof is superior in electric insulation, mechanical characteristics, etc.
