摘要:
Dyes of the formula I ##STR1## in which A is phenyl or phenyl substituted by chloro, bromo, nitro, methyl, ethyl, methoxy or ethoxy; B.sup.1 is hydrogen, chloro, bromo, nitro, methyl or trifluoromethyl; B.sup.2 is hydrogen, chloro, bromo or nitro; R is C.sub.1 to C.sub.4 alkyl; and X is hydrogen, chloro or bromo. The compounds are distinguished by high color strength, brilliance and good fastness properties such as light-fastness, fastness to overspraying, plasticizers fastness and insolubility in most solvents used in connection with pigments. They are particularly suitable for the coloring of air-drying surface coatings, rigid polyvinyl chloride and emulsion paints.
