    • The invention relates to a mixture of at least two different pigments of the formula ##STR1## with the difference lying in the meanings of the radicals A and B, in which the formula (I) A and B are the same or different alkyl, aralkyl, cycloalkyl, carbocyclic or heterocyclic aromatic radicals, which mixture of pigments is obtainable by(a) reacting 1 mole of a disuccinate with 1.75 to 1.998 moles of a nitrile of the formula ACN and 0.002 to 0.25 mole of a nitrile of the formula BCN or of a mixture of several nitriles of the formula BCN, the radicals B of which are different from A, or(b) reacting 1 mole of a lactam of formula (II) or of an enamine of formula (III) ##STR2## in which formula each of R and R' independently of the other is alkyl or aryl, with 0.75 to 0.998 mole of a nitrile of the formula ACN and 0.25 to 0.002 mole of a nitrile of the formula BCN or of a mixture of several nitriles of the formula BCN, the radicals B of which are different from A, in an organic solvent, in the presence of a strong base and at elevated temperature, and subsequently hydrolyzing the resultant reaction product.The mixture of pigments is suitable for coloring material of high molecular weight, in particular plastics and lacquers, in red shades of excellent fastness properties.
    • 本发明涉及式(I)的至少两种不同颜料的混合物,其中不同之处在于基团A和B的含义,其中式(I)A和B相同或不同 烷基,芳烷基,环烷基,碳环或杂环芳族基团,该颜料的混合物可通过以下步骤获得:(a)使1摩尔二琥珀酸酯与1.75至1.998摩尔式ACN腈和0.002至0.25摩尔腈 式BCN或式BCN的几种腈的混合物,其基团B不同于A,或(b)使1摩尔式(II)的内酰胺或式(III)的烯胺反应
