ABSTRACT:
A curable resin composition comprising a mixture and/or a preliminary reaction product of (a) at least one cyanate compound selected from the group consisting of polyfunctional cyanate esters, prepolymers of said cyanate esters, coprepolymers of said cyanate esters and an amine and mixtures thereof, (b) at least one compound having two or more acrylic ester groups represented by the formula ##STR1## wherein R.sup.1 is organic group comprising as member constituting a main chain or ring C and optionally O and/or N and optionally as a pendant hydroxy and/or halogen, when R.sup.1 contains aromatic group, R.sup.1 has 6-35 carbon atoms, and when R.sup.1 contains no benzene ring, R.sup.1 has 1-15 carbon atoms, X is hydrogen or methyl, n is integer of 2, 3, 4, 5 or 6 and valency of R.sup.1 is the same as n, and optionally (c) at least one compound selected from the group consisting of polyfunctional maleimides, prepolymers of the maleimides or coprepolymers of the maleimides and an amine is disclosed.
