Curable resin composition

Claim 1

A curable resin composition comprising: a) at least one maleimide compound selected from the group consisting of N-(alkenylphenyl)maleimides represented by the general formula (I): wherein R 1 -R 6 may be the same or different from one another and denote independently hydrogen, a hydrocarbon group having 1-20 carbon atoms, a halogen, R 0- or R 7 C- group(where R represents a hydrocarbon group having 1-20 carbon atoms or a hydrocarbon group having 1-20 carbon atoms and substituted by one or more halogen atoms of at least one kind), hydroxyl group, cyano group, or a hydrocarbon group substituted by one or more halogens, R 7 0- or group(where R 7 is as defined above), hydroxyl group or cyano group and having 1-20 carbon atoms prior to the substitution, a plurality of R 4 s may be the same or different when m 1 stands for a value of 2 or greater, R 3 may be coupled with either R 1 or R 2 , thereby forming a ring, X denotes at least one atom or group selected from hydrogen, halogens, hydroxyl group, R 7 0-, R 7 C- and R 7 CN- groups(where R is as defined above), cyano group, nitro group and carboxyl group, a plurality of Xs may be the same or different when m 2 stands for a value of 2 or greater, and m 1 , m 2 and m 3 represent independently a positive integer and m l , + m 2 + m 3 = 5, dimers of said maleimides and polymers of said maleimides having a polymerization degree of at least 3; and b) one or more kinds of epoxy resins, each having at least one epoxy group in the unit molecule thereof.
