摘要： A composition containing an organic pigment, the particles of which pigment are provided with a tenacious, dense, highly crosslinked coating of ethyl cellulose.Pigment compositions of this kind are distinguished in particular by their color strength, by their excellent rheological properties in varnish and printing ink systems, by the high gloss of the finishes obtained therewith, and by the substantial non-deformation of the plastic mouldings pigmented therewith.
摘要翻译：含有有机颜料的组合物，其颜料的颗粒设置有坚韧，致密，高度交联的乙基纤维素涂层。通过其在清漆和印刷油墨系统中的优异的流变性能，通过其获得的表面光泽度的高光泽度和通过其着色的塑料模制品的基本上不变形来区分这种颜料组合物的着色强度。

摘要： Compositions containing an organic pigment coated with metal oxides, wherein the pigment particles are provided with a tenacious, dense, highly crosslinked coating of silica and/or alumina which is fixed by polycondensation of a silicate and/or aluminate with the free hydroxyl groups of a layer that densely coats the surface of the pigment particles and which consists substantially of partially hydrolyzed compounds of elements of group 4A or 4B of the Periodic Table selected from the group consisting of chelates of formula ##STR1## wherein R is methyl, ethyl, methoxy or ethoxy, R.sup.1 is methyl or ethyl and X is halogen or C.sub.1 -C.sub.4 alkoxy, and M is Ti or Sn, and of esters of formulaQ(OR.sup.2).sub.4 (III),wherein Q is an element of group 4A or 4B of the Periodic Table and R.sup.2 is C.sub.1 -C.sub.4 alkyl.Pigment compositions of this kind are distinguished in particular by excellent rheological properties in varnish and printing ink systems, by high gloss of the finishes obtained therewith, and by substantial non-deformation of the plastic mouldings pigmented therewith.
摘要翻译：包含涂覆有金属氧化物的有机颜料的组合物，其中所述颜料颗粒设置有坚固，致密，高度交联的二氧化硅和/或氧化铝的涂层，其通过硅酸盐和/或铝酸盐与一种硅酸盐和/或铝酸盐的游离羟基的缩聚固定层，其密集地涂覆颜料颗粒的表面，并且其基本上由元素周期表中的4A或4B族元素的部分水解化合物组成，其选自由式（I）或（IMAGE）（II）的螯合物组成的组）其中R是甲基，乙基，甲氧基或乙氧基，R1是甲基或乙基，X是卤素或C1-C4烷氧基，M是Ti或Sn，和式Q（OR2）4（Ⅲ）的酯，其中Q是元素周期表的4A或4B族元素，R2是C1-C4烷基。这种颜料组合物特别是通过在清漆和印刷油墨体系中的优异的流变性能，通过其获得的表面光泽的高光泽度和通过其着色的塑料模制品的基本不变形来区分。
