摘要： PURPOSE:To improve image preservability, the whiteness degree of a recording layer and coloring properties by providing the recording layer containing specific colorless or pale basic dye and a specific developer which develops a color through contact with the former, on a support. CONSTITUTION:The subject medium contains 2-di-n-butylamine-6-methyl-7- phenylaminofluoran as a basic dye and alpha-naphthoic acid and/or its zinc salt as a developer. The application liquid is prepared by dispersing the basic dye and the developer together or individually using a stirrer/crusher with the assistance of water as a dispersant and is applied to a sheet or a plastic film using a known application device. Thus the medium obtained has characteristic of its extremely superb stability of the background and a recorded image against various solvents, its ability to prevent an image from becoming discolored or faded, if preserved under environments at high temperature and humidity and its enhanced whiteness degree and coloring density of the recording layer.

摘要： PURPOSE:To obtain a sensitive thermal recording material having high brightness and very little refuse adhering to a thermal head by containing calcium sulfoaluminate in a recording layer. CONSTITUTION:To form a thermal recording material, a thermal recording layer containing a color coupler and a coloration agent for coloring the color coupler on heating is provided on a support and calcium sulfoaluminate is contained in the recording layer. The calcium sulfoaluminate to be used is an artificial pigment obtained when aluminum sulfate and calcium hydroxide are caused to react with each other and its chemical composition is generally represented by 3CaO.Al2O3.3CaSO4.32H2O but its composition ratio changes according to the mixing ratio of raw materials. The usage ratio of the calcium sulfoaluminate is determined according to an adhesive to be combined, pigment to be used jointly, etc., and not necessarily limited, but it is desirable to use the sulfoaluminate in the range of 0.1-50wt.% for the total solid of a dried coating liquid in the thermal recording layer. Thus, it is possible to obtain a sensitive thermal recording material having high brightness and very little refuse adhering to a thermal head.
