摘要： PIGMENTS ARE DISCLOSED HEREIN WHICH CONSIST OF , PER MOLECULE, TWO BENZENE-AZO-2-HYDROXY-3-CARBAMOYL-NAPHTHALENE DYESTUFF RADICALS IN WHICH EACH OF THE TWO BENZENE NUCLEI IS SUBSTITUTED BY TWO CARBOXYLIC ACID ESTER GROUPS, ESPECIALLY TWO LOWER ALKOXY-CARBONYL GROUPS, ONE OF WHICH IS IN O-POSITION TO THE AZO BRIDGE AND THE OTHER IS IN P-POSITION TO THE FORMER ESTER GROUP, AND THE CARBAMOYL GROUPS OF WHICH MOIETIES ARE LINKED BY A BRIDGE MEMBER BONDED TO THE TWO NITROGEN ATOMS OF SAID CARBAMOYL GROUPS; THESE NOVEL PIGMENTS ARE DISTINGUISHED BY PURE, VIVID SHADES, GREAT COLOUR STRENGTH AND VERY GOOD FASTNESS PROPERTIES. THE PIGMENT IN WHICH THE CARBOXYLIC ACID ESTER GROUPS ARE METHOXYCARBONYL GROUPS AND THE BRIDGING MEMBER IS PHENYLENE IS DISTINGUISHED BY AN UNEXPECTED CARMINE-RED SHADE OF GREAT PURITY AND STRENGTH OF COLOUR. THESE PIGMENTS ARE SUITABLE FOR THE PIGMENTING OF POLYMETIC ORGANIC MATEIAL, PARTICULARLY PLASTICS SUCH AS POLYVINYLCHLORIDE AND OF PRINTING INKS FOR THE GRAPHIC INDUSTRY AND IN FINELY DISTRIBUTED FORM ALSO FOR THE PIGMENTING OF CURABLE RESINS AND CELLULOSE ESTERS.
