PURPOSE: To provide a heat sensitive recording material with fade index more than 45. CONSTITUTION: This heat sensitive recording material is composed of a substrate (support material), a binder, a chromogenic material, an electron-accepting color developer which reacts with the 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 cyclic hydrocarbon. The color stabilizing resin, chromogenic materials, and developer, have a weight percent resin phenolic group of about 5 or less. |
