Abstract
PURPOSE: To obtain multi-color heat-sensitive recording material improved in reservability thereof by laminating two heat-sensitive colorific layers colorified with different colors and lendering terephthalic acid added with ethylene oxide to exist in the upper heat-sensitive colorifying layer.
CONSTITUTION: Two heat-sensitive colorifying layers having different colorifying temperatures and shades are formed on a supporting member. In a multi-color heat-sensitive recording material, in which the heat-sensitive colorifying component of an upper layer, at least, is consisting of leuco dye, colorless or thin colored, and phenolic or acidic substance, terephthalic acid added with ethylene oxide is existed in the upper heat-sensitive colorifying layer or both layers. The leuco dyes adapted for it are: 3,3-Vis (p-dimethylaminophenyl)-phthalid; 3-cyclohexyl amino-6-chrolfluorene; and the like. The phenolic substances adapted for it are: 3,5-xylenol; thymol and the like.
