Heat sensitive record type magnetic ticket seat

摘要

PURPOSE:To provide a thermal recording type magnetic ticket sheet, which has blocking resistance in high temperature and humidity, in which there is no desensitization of a heat sensitive layer and which has excellent magnetic characteristics and heat sensitive characteristics. CONSTITUTION:Polyethylene oxide having weight average molecular weight from one hundred thousand to two million and five hundred thousand and wax are used as the magnetic recording layer of a thermal type magnetic ticket sheet, in which the magnetic recording layer is formed on one surface of a supporter and a recording layer on the other surface. An overcoating layer is often formed onto a heat sensitive layer. The blocking properties of a magnetic layer and the heat sensitive layer or the magnetic layer and the overcoating layer in high temperature and humidity are improved, and the desensitization of the heat sensitive layer due to the transition, etc., of the desensitizing substance of the magnetic layer is enhanced.
