Heat sensitive record type magnetic ticket seat

摘要

PURPOSE:To obtain a superior thermal response of a thermal recording layer, a whiteness of a non-printing part, and an improved shelf stability of a thermal color image by a method wherein the thermal recording layer contains an aromatic isocyanate compound, an imino compound, and a binder as main components and a hot melt substance having a specific melting point. CONSTITUTION:On one surface of a substrate, a magnetic recording layer formed by applying an aqueous coating liquid or organic solvent coating liquid mainly composed of a ferromagnetic powder and a binder is provided. On the other surface, a thermal recording layer containing an aromatic isocyanate compound, an imino compound, and a binder as main components and a hot melt substance having a melting point of 60 - 180 deg.C is formed. In this manner, a magnetic ticket sheet having a good shelf stability of a thermal recording image can be obtained. Especially, when the gel content of the binder in the magnetic recording layer is 5 - 75%, the magnetic ticket sheet can be further improved in whiteness of the thermal recording layer and shelf stability of a recording image.
