Abstract

PURPOSE:To obtain a heat-sensing recording type magnetized security paper with improved heat-matching performance, etc., which is able to be preserved safely for a long period of time, by providing a magnetic recording layer on one side of a supporting body, and also providing the other side of the supporting body with a thermal coloration layer and a protective layer composed of a water-soluble high molecular compound. CONSTITUTION:A dispersion liquid, which is obtained by dispersing magnetic powder onto resin or water-soluble binder, is coated and dried on one side of a supporting body to provide thereon a magnetic recording layer, and then, on the other side of the supporting body, a liquid, in which 1.0wt% in total of colorless leuco dyestuff[such as, 3,3-vis(P-dimethylaminophenyl)-phthalate, etc.]and a coloring auxiliary and also respective contents of 0.1-10% and 0.1-0.5% of compounds (such as, N-octadecilcarbamoil benzene, etc.) which are expressed by formulasIand II (R1: alkyl of C1-30; R2 and R3: alkyl of C10-30) are dispersed together with a binding agent, is coated and dried to provide a heat-sensing coloration layer, and then, water solution of a water-soluble high molecular compound is coated and dried.
