Curable resin composition comprising N-(alkenylphenyl)maleimide and epoxy composition

Claim 1

A curable resin composition comprising: (a) at least one N-(alkenylphenyl)maleimide represented by the general formula (I): ##STR6## wherein R 1 -R 6 are the same or different from one another and denote independently hydrogen, a hydrocarbon group having 1-20 carbon atoms, a halogen, R 7 O- or ##STR7## group, where R 7 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, hydroxyl group, cyano group, or a hydrocarbon group substituted by one or more halogens, R 7 O- or ##STR8## 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 are the same or different when m 1 stands for a value of 2 or greater, R 3 is 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, ##STR9## groups, where R 7 is as defined above, cyano group, nitro group or carboxyl group, a plurality of Xs are 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 1 ,+m 2 +m 3 =5, dimers of said maleimides and polymers of said maleimides having a polymerization degree of at least 3; and (b) at least one epoxy compound, each having at least one 1,2-epoxy group in the unit molecule thereof.
