IPC: B41M5/30
Filed: 1991-11-11
Abstract: PURPOSE:To develop a new type of electron-receptive color developer and thereby obtain a thermal recording material having superb image preservation stability and excellent rapid recording properties by composing an electron- receptive color developer using a fatty acid derivative with a halogen group and preparing the thermal recording material using a chemical reaction between the color developer and a coloring agent. CONSTITUTION:An electron-receptive color developer is composed using a fatty acid derivative having a halogen group (e.g. 3-promopentanic acid). Next, a thermal recording material is obtained by using a chemical reaction between the color developer and the coloring agent (e.g. crystal violet lactone). This color developer, of a new type, is used as a solution-type coating liquid, when a thermal color developer is prepared in combination with the electron-donative coloring agent. Thus a thermal recording material with excellent preservation stability and rapid recording properties can be obtained. In addition, it is easy to prepare a transparent recording material, so that the recording material on which data is recorded using an OA equipment with a thermal head can be used as OHP recording material.
