摘要: An improved heat-sensitive recording material is disclosed comprising a substrate, a binder, a chromogenic material, an electron-accepting color developer which reacts with said chromogenic material to form a color, and a color-stabilizing resin. The color stabilizing resin comprises an addition product of a diolefinic alkylated or alkenylated cyclic hydrocarbon or, an addition product of a phenol and a diolefinic alkylated or alkenylated cyclic hydrocarbon. The color-stabilizing resin, dye, and developer, have a weight percent resin phenolic group of about 5 or less. The heat-sensitive recording material has a fade index greater than 45. Imaged recording materials according to the invention resist fading when exposed to temperatures of 60.degree. C. for prolonged periods such as twenty-four hour oven tests.
