Abstract

Disazo pigments of general formula <FORM:1037988/C4-C5/1> in which Hal is halogen, either both X's are hydrogen atoms or alkyl or alkoxy groups or one X is a hydrogen atom the other being a halogen atom or an alkyl, alkoxy, cyano or trifluoromethyl group and Z is a hydrogen or halogen atom or an alkoxy group, are prepared by reacting an acid chloride of formula <R/2> with a diamine of formula <FORM:1037988/C4-C5/2> or by coupling a diazotized 2-nitro-4-halogenoaniline with a compound of formula <FORM:1037988/C4-C5/3> or with a compound of formula <FORM:1037988/C4-C5/4> The -CH2A in which A is an amine group is split off and replaced by the diazo compound. The preferred compounds are those in which the halogen is chlorine and both X's are methyl groups. The pigments give brown colours.ALSO:Disazo pigments of general formula <FORM:1037988/C3/1> in which Hal is a halogen atom, both X's represent hydrogen atoms or alkyl or alkoxy groups or one X is hydrogen and the other X is a halogen atom or an alkyl, alkoxy, cyano or trifluoromethyl group and 2 is a hydrogen or halogen atom or an alkoxy group, are incorporated into, polyvinyl chloride-dioctylphthalate mixture (Example 4) an alkyd melaminetitanium dioxide stoving lacquer (Example 5), and into a nitrocellulose-titanium dioxide lacquer (Example 6), or into various other resins mentioned generally.
