Abstract
PURPOSE:To improve the recording material so that its shelf life does not degrade by using alkylene oxide adduct of bisphenols as a discoloring agent which discolors low temperature heat-sensitive color forming components when colored at high temperature. CONSTITUTION:A high temperature heat-sensitive color forming layer 2 is formed on a substrate 1 such as paper by using a known heat-sensitive color forming system. On this is provided a low temperature heat-sensitive color forming layer 3 comprising dispersing a color former 5 composed of colorless or pale color leuco dyes coloring to the tone differing from that of the layer 2, a developer 6 composed of phenolic material and a discoloring agent 7 composed of the alkylene oxide adduct of bisphenols of formula (A is methylene, 2-alkylidene of C3-4; X is H, halogen; m is 2 to 4; n, n' are 1 to 5) in a binder. The discoloring agent 7 is used at a ratio of 0.5 to 5.0pts.wt. based on 1pt.wt. of the total weight of the color former 5 and developer 6.
