Definitions
- the invention relates to a heat-sensitive recording sheet in which the color image and the whiteness of the background are surprisingly well stabilized against the adverse effects of hair oil, fat, oil, etc.
- a heat-sensitive recording sheet using a heat color reaction between a basic colorless or lightly colored chromogenic dye and an organic color developing agent such as a phenolic substance or an organic acid is disclosed in Japanese Patent Publication Nos. 4160/1968 and 14039 / 1970, and described in Japanese Patent Laid-Open No. 27736/1973. It has many practical uses.
- a heat-sensitive recording sheet is generally prepared by applying a coating paint to the surface of the support such as paper, film, etc., which is prepared by grinding and dispersing a colorless chromogenic dye and a color developing material, phenolic substances, into fine particles by mixing the dispersions obtained and by adding a binder, filler, sensitizer, lubricant and other auxiliaries.
- the oily materials are the color-forming layer consisting of a basic colorless chromogenic dye of fine particles and an organic color developing agent of fine particles, or the color-forming reaction product which is made of a basic colorless chromogenic Dye and an organic color developing agent is formed, partially dissolve or destabilize.
- the heat-sensitive recording sheets in which 4-hydroxybenzoic acid ester or 4-hydroxyphthalic acid diester are used are superior in the above fundamental qualities, but in terms of the stability to oily materials, they are superior to the previous heat-sensitive recording sheets in which bisphenol compounds as color developing agents used, inferior.
- the invention has for its object to provide a heat-sensitive recording sheet in which the recording image is very stable against the action of oily materials.
- the above metal salt of a nitrobenzoic acid brings about both very good color development and superior stability of the recording image, so that it can be used as a color developing agent and / or can improve stability in combination with other color developing agents.
- color developing agents other than the metal salts of nitrobenzoic acid used in the present invention, but the effects of this invention are significant when monophenolic 4-hydroxyphenyl compounds and / or phthalic acid monoesters are used as the color developing agents.
- Examples of monophenolic 4-hydroxyphenyl compounds are 4-hydroxybenzoic acid esters, for example propyl 4-hydroxybenzoate, isopropyl 4-hydroxybenzoate, butyl 4-hydroxybenzoate, 4-hydroxybenzoate, 4-hydroxybenzoate, 4-hydroxybenzoate, etc.
- 4-hydroxyphthalic diesters for example dimethyl 4-hydroxyphthalate, diisopropyl 4-hydroxyphthalate, dibenzyl 4-hydroxyphthalate, di-4-hydroxyphthalate, etc.; 4-hydroxyacetophenone; p-phenylphenol; Benzyl-4-hydroxyphenylacetate; p-benzylphenol; 4-hydroxyphenyl-4'-n-sulfone, 4-hydroxyphenyl-4'-n-butyloxyphenylsulfone, 4-hydroxyphenyl-4'-n-hexyloxyphenylsulfone, 4-hydroxyphenyl-4'-n-octyloxyphenylsulfone, 4-hydroxyphenyl-4 ' -n-decyloxyphene sulfone, 4-hydroxyphenyl-4'-n-dodecyloxyphenyl sulfone, 4-hydroxyphenyl-4'-benzyloxyphenyl sulfone, 4-hydroxyphenyl-4'-p-isopropylbenzy

- Such color developing agents are superior in terms of the quality required in principle, but have a disadvantage that they are inferior to the bisphenol compounds which have hitherto been used in terms of stability to oily materials.
- bisphenol compounds examples include 4,4'-isopropylidenediphenol (bisphenol A); 4,4 '- (1-methyl-n-hexylidene) diphenol; 4,4'-cyclohexylidenediphenol; 4,4'-thiobis (4-tertiary-butyl-3-methylphenol) and the like.
- bisphenol A 4,4'-isopropylidenediphenol
- 4,4'-cyclohexylidenediphenol 4,4'-thiobis (4-tertiary-butyl-3-methylphenol) and the like.

- the following dyes from the black color developing fluoran dyes yield a heat sensitive recording sheet with a little low image density: 3-diethylamino-6-methyl- (para-chloroanilino) fluorane, 3-diethylamino-7- (ortho-chloroanilino) fluorane, 3- (N-ethyl-P-toluidino) -6-methyl-7-anilinofluorane, 3-dibutylamino-6-methyl- (ortho-chloroanilino) fluorane, 3- (N-ethyl-isoamyl) -6-methyl-anilinofluorane, etc.
- thermochromic phenomenon occurs in which the color image is extinguished immediately or slowly. Therefore, these dyes cannot be used in heat-sensitive recording sheets.
- this thermochromic phenomenon is eliminated by using the metal salt derivatives according to the invention of nitrobenzoic acid, which means that the above basic colorless dyes can be used.
