    摘要: AND THEIR USE FOR THE DYEING AND PRINTING OF CELLULOSECOTAINING MATERIALS, SUCH AS NATIVE AND REGENERATED CELLULOSE. THE NEW DYESTUFFS ARE ALSO SUITABLE FOR DYEING MATERIALS CONTAINING AMIDE GROUPS, SUCH AS WOOL, SILK AND SYNTHETIC POLYAMIDES. DYEINGS OBTAINED ON CELLULOSE-CONTAINING TEXTILE MATERIALS ARE DISTINGUISHED BY VERY GOOD FASTNESS PROPERTIES, ESPECIALLY FASTNESS TO LIGHT AND TO WET PROCESSING.

    摘要: Compared to the parent compound, phthalimidomethyl derivatives of 2-(2-hydroxyphenyl)benzothiazole have much lower vapor pressure and greatly improved ultraviolet stability. Both of these factors make these derivatives much better organic phosphors than the parent compound since they have greatly improved the useful lifetime of compositions where they have been incorporated to impart fluorescent properties. These new derivatives fluoresce with a yellow color.

    摘要: A method of preparing heterocyclic derivatives selected from the formulae:

    WHEREIN X is selected from hydrogen, lower alkyl, lower alkoxy, and halogen; Y is selected from hydroxy and X; Z is selected from nitrogen, oxygen, and sulfur by reacting an o- aminobenzenethiol, o-aminophenol, or o- aminoaniline and substituted derivatives thereof with an ortho-substituted benzoic acid or 2-substituted naphtholic acid in the presence of a catalyst comprising phosphorus trichloride. The compounds produced by the process of the present invention are useful as stabilizers in various organic media, e.g., organic plastics, oils, etc. and as intermediates in the production of dyestuffs and fluorescent compounds.
