Thermoreversible recording medium, apparatus utilizing the same and method for fabricating the same.

摘要

A thermoreversible recording medium which permits reversible recording and erasure to be repeated by use of a heating means, such as a thermal head or a laser, and is used for example; for storage, display or printing of image or other information, comprises a matrix material and an organic substance of low molecular weight. The matrix material essentially consists of a copolymer of styrene and butadiene, and the organic substance is a saturated carboxylic acid. The saturated carboxylic acid may preferabiy be capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, arachic acid, behenic acid or lignoceric acid. These compounds are saturated carboxylic acids with 10 - 24 carbon atoms. The weight ratio between the matrix and the organic substance is set within 1:1 to 20:1.
