Abstract: Ternary resin blends which can be cured in order to form a cured resinous material for use as a matrix in composite materials. The ternary resin blends comprise a polyfunctional cyanate ester, an asymmetric bisphenol-derived cyanate ester, and a compound of formula (I) wherein R1, R2, R3, R4, R5 and R6 are as defined in the specification. A cured resinous material prepared by curing a ternary resin blend, a composite material comprising said cured resinous material, an article comprising said cured resinous material or said composite material, and methods for making the ternary resin blends, cured resinous materials, composite materials and articles are also disclosed.
