Abstract
Abstract The thermosetting resin composition of the present invention is prepared by mixing an aromatic cyanamide compound with a cyclic ester compound and/or a cyclic amide compound. Although a solventless type composition is preferable, the present invention is not limited thereto. The cured product of the present invention can be prepared by heating and curing said thermosetting resin composition. The obtained cured product of the present invention usually contains melamine rings, isomelamine rings and linear polyester and/or a linear polyamide units.
