Abstract

PURPOSE:To improve the preservation life of a multicolor heat-sensitive recording material by using glycerin fatty acid ester as an erasing agent for erasing low temperature heat-sensitive coloring component when coloring the material at high temperature with two coloring layers coated on a support. CONSTITUTION:Two heat-sensitive coloring layers coloring at different temperature and color tone are coated sequentially on a support. The upper layer contains colorless or pale leuco dye and phenol or acidic substance in the coloring component of the multicolor heat-sensitive recording material. Glycerin fatty acid ester is existed between the two heat-sensitive coloring layers or in the upper heat-sensitive coloring layer. The glycerin fatty acid ester may preferably be a glycerin fatty ester synthesized with higher fatty acid containing more than ten carbons as a stock.
