摘要： PURPOSE:To obtain a thermosensitive recording medium having high recorded image preservability, especially, superior index-proof properties by adding a chemical compound of a salicylic acid derivative, at least one type of its polyvalent metal salt and a water-insoluble epoxy group, expressed by a specific formula as a color developer, to a recording layer. CONSTITUTION:The thermosensitive recording medium consists of a recording layer containing a color developer which develops a color through the contact between colorless or pale basic dye and basic dye, provided on a support. A chemical compound of a salicylic acid derivative, at least, one type of its polyvalent metal salt and a water-insoluble epoxy group, expressed by formula I, II as a color developer, is added to a recording layer. Ar is a phenyl group, a naphthyl group and a heteroaromacyclic group which may have a substitution group; and Q is an ether bond or a sulfonyl bond. In addition, A is a branched or straight chain alkylene group which may have an ether bond, an ester bond, an amide bond or an unsaturated bond.

摘要： PURPOSE:To obtain a thermosensitive recording body that is extremely preservative in raw even in an environment at high temperature by making said body contain at least one out of alpha-naphthoic acid or its polyvalent metallic salt as a coloring agent, and benzotriazole compound as a sensitizer. CONSTITUTION:For making up of a thermosensitive recording body, alpha-naphthoic acid and/or its multivalent metallic salt are used as a coloring agent, and benzotriazole compound is selectively added thereto as a sensitizer. It is desirable to use divalent, trivalent, or tetravalent metals as zinc, calcium, magnesium, aluminum, tin, or iron for composing of the multivalent metallic salt for the alpha-naphthoic acid, and zinc is the most desirable one. The alpha-naphthoic acid or its polyvalent metallic salt is generally used in 50-700 weight parts for 100 weight parts of basic dye, and it is preferable that the adjustment is made in a range of approximately 100-500 pts.wt.

摘要： PURPOSE:To improve image preservability, the whiteness degree of a recording layer and coloring properties by providing a recording layer containing a colorless or pale specific basic dye and a specific developer which develops color through chemical reaction with the dye, on a support. CONSTITUTION:The subject thermal recording medium consists of 3-di-n- benthylamino-6-methyl-7-phelaminofluoran as a basic dye and alpha-naphthoic acid and/or its zinc salt as a developer. An application liquid is prepared by dispersing the basic dye and the developer together or separately using a stirrer/crusher with the assistance of water as a dispersant. Thus the medium obtained is highly stable against a variety of solvents on the background and recorded image and is free from the discoloration and color fading of a recorded image if preserved under high-temperature, high-humidity environments and is capable of an enhanced whiteness degree and coloring density of the recording layer.

摘要： PURPOSE:To obtain a thermal recording material not generating the fog of a blank part and the deterioration of recording density even when exposed to temp. environment by using a specific basic dye and a specific coupler in a specific ratio. CONSTITUTION:In a thermal recording medium utilizing the color forming reaction of a colorless-light-colored basic dye and a coupler capable of forming a color upon the contact with the dye, as the basic dye, 3-di(n-butyl)amino-6- methyl-7-phenylaminofluorane is used and, as the coupler, at least one of 4,4' isopropylidenephenol, 4-hydroxy-4'-isopropoxydiphenylsulfone and 2, 2-bis(4- hydroxyphenyl)-4-methylpentane is used. 150-250 pts.wt. of the coupler is used per 100 pts.wt. of the basic dye. When the coupler is less than 150 pts.wt., developed color density is markedly lowered and, when the coupler is more than 250 pts.wt., the fading preventing effect of a printed part under high temp. environment is lowered. This thermal recording medium is reduced in the fog of a blank part at high temp. even when a heat-meltable substance is together used as a sensitizer.
