Abstract

PURPOSE:To prevent discoloration of a recording paper in a high temperature and high humidity atmosphere by allowing its recording layer, containing a colorless color-generating plant and phenolic compound, to contain a particular couromane indene resin. CONSTITUTION:In a heat-sensing recording paper containing a colorless or plain color color-generating plant and a phenolic compound, a recording layer of the recording paper is allowed to contain preferably 1-20% of couromane indene resin composed mainly of a copolymer of couromane indene and styrene which can be expressed by a formula.
