There are described silane anthraquinone dyes, composite pigments obtainable therefrom by grafting onto an
The dyes have the general formula: inorganic substrate or support, and processes for preparing the same.
in which: R, is an alkyl group containing up to 4 carbon I atoms or a phenyl group; R2 is an alkoxyl group containing I up to 4 carbon atoms; n is 3, 4 or 5; q is 0 or 1; p and m are integers such that, when q is 0, p is 3 and m is 0, 1, 2 or 3, and when q is 1, p is 2 and m is 0, 1 or 2; r is 1 or 2; and X represents a divalent amino (-NH-) or amido (-NHCO-) residue, linked to the alpha or beta positions of the anthraquinone nucleus when r is 1, or linked to the alpha positions I of the anthraquinone nucleus when r is 2, and the anthraquinone nucleus may be substituted by one or more R groups selected from -NH2, -NH-alkyl C1-C4, -NHCO-CH3, -NH-phenyl or -NHCO-phenyl in which the phenyl group is optionally substituted, -OH, -OCH3, 0-phenyl, -CH3, -Cl or Br, and -NO2.
The composite pigments obtained from said dyes are utilized in paints, air and stove enamels, in the pigmentation of plastics and in printing inks.
本发明描述了硅烷蒽醌染料、通过接枝到无机基底或支撑物上而获得的复合颜料、以及制备这些染料的工艺。
这些染料的通式为:无机基底或支架,以及制备这些染料的工艺。
其中R,是最多含有 4 个碳原子的烷基或苯基;R2 是最多含有 4 个碳原子的烷氧基;n 是 3、4 或 5;q 是 0 或 1;p 和 m 是整数,当 q 是 0 时,p 是 3,m 是 0、1、2 或 3,当 q 是 1 时,p 是 2,m 是 0、1 或 2;r 是 1 或 2;和 X 代表二价氨基(-NH-)或氨基(-NHCO-)残基,当 r 为 1 时与蒽醌核的α或β位相连,或当 r 为 2 时与蒽醌核的α I 位相连、蒽醌核可被一个或多个 R 基团取代,这些 R 基团选自-NH2、-NH-烷基 C1-C4、-NHCO-CH3、-NH-苯基或其中苯基被任选取代的-NHCO-苯基、-OH、-OCH3、0-苯基、-CH3、-Cl 或 Br 以及-NO2。
从上述染料中得到的复合颜料可用于涂料、空气和炉灶瓷漆、塑料颜料和印刷油墨。
