Application | resorcinol tetraphenyl diphosphate may be used to prepare a thermosetting cyanate ester resin composition comprising the following components: polyfunctional Cyanate esters, epoxy resins and flame retardants. The thermosetting cyanate ester resin composition further comprises an inorganic filler. The thermosetting resin composition of the present invention is useful for preparing resin sheets, resin composite metal copper foils, prepregs, laminates, copper clad laminate, Printed Wiring Boards, and the like. The resin composition of the present invention is excellent in heat resistance, moisture resistance, flame retardancy and low coefficient of thermal expansion. The phosphorus-based flame retardant is selected from the group consisting of Tris (2, 6-dimethylphenyl) phosphine, resorcinol bis [BIS (2, 6-dimethylphenyl) phosphate], resorcinol tetraphenyl diphosphate, and the like. |
