Salts of laked monoazo compounds

Abstract

The present invention relates to monoazo compounds of formula (1) wherein R1 is hydrogen, halogen, especially chlorine, or C1-C4alkyl, especially methyl, and R2 is halogen, especially chlorine, or C1-C4alkyl, especially methyl, preferably one of the substituents R1 and R2 being halogen and the other substituent being C1-C4alkyl, which are present in the form of salts or mono-, di-, tri- or tetra-valent mixed salts of different cations, such as, for example, Ca2+, Na+, NH4+, NR4+, H+, Li+, K+, Mg2+, Ba2+, Sr2+, Al3+, Pb2+, Mn2+, Zn2+, Cr2+, Co2+, Fe2+, Fe3+, Zr4+ and Cu2+ wherein R is C1-C6alkyl, in freely selected ratios, to processes for their preparation and to their use in the mass-pigmenting of organic materials and in the production of toners, wax transfer ribbons or colour filters.
