摘要： PURPOSE:To obtain a thermal recording material capable of forming a developed color image excellent in oil resistance by together using a specific org. compd. known as the so-called curing agent in a combination consisting of a colorless or light-colored dye precursor, a developer and an aziridine compd. or an epoxy compd. CONSTITUTION:A thermal color forming layer containing a colorless or light- colored dye precursor, a developer developing a color upon the reaction with the dye precursor under heating and an org. compd. having at least one aziridine or epoxy group is provided on at least one surface of a sheet like support. At least one kind of a compd. selected from an org. compound having an amino group or a group having a chemical structure represented by formula I and an org. compd. having a carboxyl group or a -CO-O-CO- group is further added to the thermal color forming layer.

摘要： PURPOSE:To form a colored image with good preservative properties and safety by adding a specific oxazolidine compound and/or a specific oxazoline compound to a heat-sensitive coloring layer containing a developer which reacts with a dye precursor formed in a sheet-like base material with heat thereby to develop colors. CONSTITUTION:At least at one surface of a sheet-like base of the heat-sensitive recording body are formed a colorless or light-colored dye precursor and a heat-sensitive coloring layer containing a developer which reacts with the dye precursor when receiving heat thereby to develop colors. In this case, at least one selected from oxazolidine compounds and oxazoline compounds represented by the respective general formula is added to the heat-sensitive coloring layer. In each formulae, (n) is an integer of 1-3, A is a substituted or not-substituted aryl group of (n) valences, and R represents a hydrogen atom, alkyl group or aryl group. Accordingly, the obtained heat-sensitive recording body forms colored images with good preservative properties and safety.

摘要： PURPOSE:To obtain a thermal recording material generating no background fog at the time of high temp. by preventing the formation of a hydrate in a wet dispersion process of 4-hydroxy-4'-isopropoxydiphenylsulfone used as developer. CONSTITUTION:When 4-hydroxy-4'-isopropoxydiphenylsulfone is finely pulverized by wet dispersion, a hydration inhibitor composed of at least one kind of a compd. selected from methyl cellulose and hydroxyethylemethyl cellulose is used to obtain a developer. A thermal recording material is constituted by forming a thermal color forming layer containing the developer thus obtained on a sheet like support.

摘要： PURPOSE: To enhance the contrast of a developed color hue and an erased color hue by preparting a coupler allowing a colorless or light-colored dye precursor to reversibly develop and erase a color under heating by adding an aromatic compd. having a specific sulfonyl(thio)urea group and an alkyl group. CONSTITUTION: In a dye type reversible thermal recording material utilizing the reaction of a dye and a coupler, at least one kind of an aromatic compd. having at least one sulfonyl(thio)urea group represented by the general formula (wherein X is an oxygen atom or a sulfur atom) and at least one 11 or more C alkyl group in one molecule thereof is added to a coupler allowing a colorless or light-colored dye precursor to reversibly develop and erase a color under heating. At the time of the reversible color development and erasure of the recording material, the thermal color forming layer of a recording display material is heated to record a developed color image and heated to a temp. lower than the color forming temp. after use to erase the developed color image.
