Abstract: BENZOXANTHENE OR BENZOTHIOXANTHENE DYESTUFFS CONSISTING OF A MIXTURE OF ISOMERS OF THE FORMULAE

X
BENZOFURO(3,2-B)PHENALEN-3,4-YLENE)-), AND 8-(O=),

6-R5,15-R6,R3,R4,R1,R2-8H-BENZOFURO(2'',3'':5,6)NAPHTHO-

(2,1,8-M,N,A)ACRIDINE

IN WHICH X IS OXYGEN OR SULFUR, R1 AND R2 ARE HYDROGEN OR HALOGEN, ALKYL, ARYL, ALKOXY, ACYL, ACYLOXY, CARBALKOXY, NITRO, ALKYLTHIO OR ALKYLSULFONYL, R3 AND R4 ARE HYDROGEN OR HALOGEN, ALKYL, ALKOXY, ARYL, CARBALKOXY OR CYANO, R5 AND R6 ARE HYDROGEN OR OPTIONALLY SUBSTITUTED ALKOXY. THE DYESTUFFS HAVE ORANGE TO BLUISH RED SHADES AND MAY BE USED FOR DYEING AND PRINTING OF SYNTHETIC MATERIALS AS WELL AS FOR MASS DYEING OF SYNTHETIC FIBER-FORMING POLYMERS. THE DYEINGS THUS OBTAINED ARE DISTINGUISHED BY A HIGH BRILLIANCE OF SHADE, GOOD FASTNESS PROPERTIES TO LIGHT AND VERY GOOD FASTNESS PROPERTIES TO WET PROCESSING AND THERMOFLXATION. FURTHERMORE, THE DYESTUFFS MAY BE USED AS FLUORESCENT DYESTUFFS FOR THE COLORING OF SYNTHETIC POLYMERS IN THE MELT.
