Abstract: HOE 79/F 022 PROCESS FOR THE PREPARATION OF 5-NITROBENZIMIDAZOLONE-(2) of the disclosure: Nitration of benzimidazolone-(2) with nitric acid in water at 20 to 100.degree.C yields 5-nitrobenzimidazolone-(2) in high yield and purity. Since no side reactions occur the mother liquor can be recycled, thus avoiding waste water problems. The product can be reduced to 5-aminobenzimida-zolone-(2) which is a diazo component for azo dyes which, in turn, can be reacted with diketene to yield 5-acetoace-tylamino-benzimidazolone which is a coupling component for azo dyes, especially pigments.

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.
