摘要:
A heat-sensitive recording paper is disclosed. The paper is comprised of a support base having a heat-sensitive color forming layer coated thereon. The color forming layer contains color forming components comprising an almost colorless electron donating dye and an organic acid capable of forming color when contacted with the dye. The color forming layer is coated with a coating layer containing polyvinyl alcohol and boric acid. Due to the existence of the coating layer the recording paper has substantial resistance to decrease the recording density and occur the fog by various chemicals and oils.
