Abstract: The abrasiveness of a pigment or printing ink is reduced by incorporation of one or more finely divided substances which are insoluble in printing inks and have a Mohs hardness of from 4.5 to 8, suitable compounds being iron powder, compounds of iron, zirconium, silicon and magnesium, aluminum silicates, oxides of manganese, tin and cerium, or mixtures of these. The printing inks obtained cause substantially less, or virtually no, abrasion of gravure printing cylinders.

Abstract: Compounds of the formula ##STR1## in which K is ##STR2## Ar.sup.1 is phenyl; phenyl substituted by chlorine, methoxy, ethoxy, methyl, acetylamino or benzoylamino; or ##STR3## Ar.sup.2 is phenyl; or phenyl substituted by chlorine, methyl or sulfamoyl,T.sup.1 is methyl or carbamoyl,T.sup.2 is cyano or carbamoyl,Z is hydrogen, chlorine, bromine or trifluoromethyl,Z.sup.1 is hydrogen, chlorine, or bromine, andR is phenyl; phenyl substituted by chlorine, bromine, hydroxy, methoxy, ethoxy, C.sub.1 to C.sub.4 alkyl, cyano, carbamoyl, nitro, phenyl, sulfamoyl, N-phenylsulfamoyl, acetylamino or benzoylamino; naphthyl; N-phenylphthalimidyl; or pyridyl.These compounds are dyes having mostly pigmentary character and are eminently suitable for coloring printing inks, surface coatings and resins.

Abstract: Compounds of the formula ##STR1## in which K is the radical of a coupling component;X is hydrogen, chloro, bromo, methyl or nitro; andY is hydrogen, chloro, bromo or methyl.The compounds are eminently suitable as pigments for coloring printing inks, surface coatings and resins with exceptional fastness properties.

Abstract: An azo pigment of the formula: ##STR1## in which R is hydrogen or methyl;R.sup.1 is cyano or carbamoyl;R.sup.2 is hydrogen, chloro, bromo, methyl, methoxy, ethoxy or cyano;R.sup.3 is hydrogen, chloro, bromo, methyl, methoxy, ethoxy, cyano, carbomethoxy, carbamoyl, sulfamoyl or methylsulfonyl; andR.sup.4 is hydrogen, chloro, bromo, methyl, methoxy or carbomethoxy.The compounds are eminently suitable as pigments in printing inks, surface coatings or plastics.

Abstract: Dyes of the formula: ##STR1## in which D is the radical of a diazo component;R.sup.1 is hydrogen, chloro, bromo, methoxy or ethoxy;R.sup.2 and R.sup.3 independently of one another are hydrogen, chloro, bromo, methyl, ethyl, trifluoromethyl, nitro, methylsulfonyl, ethylsulfonyl, phenylsulfonyl, unsubstituted or N-substituted carbamoyl or sulfamoyl, carboxylic ester, unsubstituted or substituted C-acylamino or phthalimidyl; orR.sup.2 and R.sup.3 together form a radical of the formula: ##STR2## The dyes are eminently suitable for coloring printing inks, surface coatings and resins with excellent fastness properties.

Abstract: A monoazo dye or pigment of the formula: ##STR1## in which D is the radical of the diazo component, preferably a diazotized compound of the aminoanthraquinone, aminophthalimide or aniline series;X is --NH or a direct bond; andY is --NH, --CONH, --NHCO or a direct bond; andWherein the rings A and B may contain from one to three substituents such as chloro, bromo, methyl, ethyl, methoxy, ethoxy, cyano, nitro, alkoxycarbonyl, trifluoromethyl, methylsulfonyl and optionally N-substituted carbamoyl or sulfamoyl radicals. The dyes or pigments are eminently suitable for coloring for example printing inks, surface coatings and resins because of their color strength and very good fastness properties.

Abstract: The production of dichlorobenzoic acids by reaction of the diazonium compound of a dichloroaminobenzoic acid with an aqueous alcohol solution of specific concentration. The compounds which can be prepared according to the process of the invention are valuable starting materials for the production of pharmaceutical substances, dyes and pesticides.
