THE DYESTUFFS ARE VERY SUITABLE FOR THE DYEING OF SYNTHETIC MATERIALS, ESPECIALLY F OR THE DYEING OF POLYETHYLENEGLYCOL TEREPHTHALATE. MOREOVER, THESE DYESTUFFS MAY BE USED AS FLUORESCENT DYESTUFF IN THE MASS DYEINGS OF SYNTHETIC POLYMERS. THE RESULTING DYEINGS ARE DISTINGUISHED BY A GOOD FASTNESS TO LIGHT, WET PROCESSING AND THERMOFIXATION.

Abstract: DAYLIGHT FLUORESCENT PIGMENTS ON THE BASIS OF CONDENSATE RESINS IN FLUORESCENT DYESTUFFS OF THE BENZOXANTHANE AND THIO-BENZOXANTHANE SERIES. THESE DAYLIGHT FLUORESCENT PIGMENTS MAY BE USED FOR PREPARING FLUORESCENT PAINTS OR PRINTING INKS AND FOR COLORING PLASTICS, ESPECIALLY VINYL POLYMERS. THEY SHOW AN INTENSE BLUISH GREEN TO YELLOW FLUORESCENCE AND HAVE A VERY GOOD FASTNESS TO LIGHT.

Abstract: 1345176 Luminescent materials FARBWERKE HOECHST AG 19 April 1971 [14 April 1970] 26913/71 Heading C4S A daylight fluorescent pigment comprises a condesnate resin and a fluorescent dye having a formula in which X is oxygen or the group >N-R, R is hydrogen or an optionally substituted alkyl, cycloalkyl or aryl radical, a heterocyclic radical, a hydroxy group or the group -NH-Z in which Z is hydrogen, an optionally substituted alkyl or aryl radical, a heterocyclic radical or an acyl, alkyl-sulphonyl or aryl-sulphonyl radical; R 1 and R 2 , which may be the same or different, represent hydrogen, a halogen atom, e.g. Br or Cl or an alkyl alkoxy, aryl, carbalkoxy or cyano group; R 3 is hydrogen or an optionally substituted alkoxy group; and R 4 is hydrogen or R 3 and R 4 both represent optionally substituted alkoxy groups. Y is oxygen or sulphur and n is zero, 1, 2, or 3. Resins include cross linked polyesters, amideformaldehydes and amino-triazine formaldehydes. Preferred dyes are benzoxanthenes and benzothioxanthenes prepared by heating diazonium salts in the presence of Cu or Cu salts. Pigment is prepared by adding benzoxanthene- 3,4-dicarboxylic acid anhydride-di-sulphonic acid and resin, then paraformaldehyde to p-toluene sulphonamide at 130‹ C. The temperature is increased to 160-170‹ C. and on cooling a brittle material forms which is ground to a particle size of 0À1-30 Á. The pigment is used for paint, laquer, printing ink or to colour plastics material.

Abstract: When reacting a dyestuff having hydroxy, acyloxy, carboxy or carbalkoxy groups with a polyester derived from terephthalic and/or isophthalic acid and, per mol of dicarboxylic acid, about 0.75 to 1.5 mol of a low-molecular alkanetriol with primary alcohol groups (methylol groups) or, instead of said polyester, with the corresponding starting materials or precondensates, a polyester with chemically linked dyestuff units is obtained which is useful for dyeing plastics, especially polyolefins. The dyed plastic materials are heat resistant, even when containing fluorescent dyestuff units, transparent and uniformly dyed.
