    Abstract: Monoazo pigments of the general formula WHEREIN X is hydrogen or halogen, preferably chlorine or bromine, alkyl, alkoxy, trifluoromethyl, phenyl, phenoxy or cyano, Y represents hydrogen or halogen, preferably chlorine or bromine, alkyl, alkoxy, carbomethoxy, phenyl or phenoxy, Z represents hydrogen, chlorine or bromine, alkyl, alkoxy, nitro, cyano, trifluoromethyl, methylsulfonyl, aminocarbonyl, alkylaminocarbonyl, phenylaminocarbonyl, aminosulfonyl, alkylaminosulfonyl, alkanoylamino or aroylamino, A represents a phenyl or naphthalene ring, n represents 1 or 2, m is an integer of from 1 to 3 and Me is an equivalent of a metal cation forming a lake and a process for preparing them by diazotizing aromatic amines of the general formula with coupling components of the general formula AND SUBSEQUENTLY CONVERTING INTO A LAKE WITH METAL SALTS, X,Y,Z,A, n and m having the above meaning. These pigments can be successfully used for dyeing all materials usually dyed with pigments. They are especially suitable for coloring high molecular plastics such as PVC and on account of their excellent resistance to heat, for coloring polyolefins.

    Abstract: 1,265,357. Water-insoluble disazo dyestuff mixtures. FARBWERKE HOECHST A.G. 9 Dec., 1969 [9 Dec., 1968], No. 60073/69. Heading C4P. Novel dyestuff mixtures consisting of mixtures of dyestuffs of the Formulae (A), (B) and (C) are prepared by coupling tetrazotized 4,4 1 - diamino-3,3 1 -dichlorodiphenyl with a mixture of 1-phenyl-3-methylpyrazolone-(5) and 1-p-tolyl- 3-methyl-pyrazolone-(5) in a molar ratio of tetrazotized diamine to pyrazolone mixture of 1 : 2. The mixtures vary in shade from yellowish orange to reddish orange depending on the proportions of the two pyrazolones in the mixtures thereof and the order of mixing when coupling. A dispersant such as an addition product of about 20 moles of ethylene oxide and 1 mole of octadecyl alcohol may be present in the coupling reaction.
