  Provided herein are ether carboxylate builder compositions comprising a combination of tartrate monosuccinic acid (or salts thereof) and tartrate disuccinic acid (or salts thereof). Such mixtures can be prepared by reacting water-soluble, mixed maleic acid salts with mixed tartaric acid salts. Both components of the resulting ether carboxylate mixture act as sequestering agents and are useful as detergency builders. Detergent and laundry additive compositions incorporating these ether carboxylates can be pre­pared without use of detergent builder components containing phosphorus or nitrogen.

  本文提供的醚羧酸盐促进剂组合物包含酒石酸单琥珀酸盐（或其盐类）和酒石酸二琥珀酸盐（或其盐类）的组合。这种混合物可通过水溶性混合马来酸盐与混合酒石酸盐反应制备。由此产生的醚羧酸盐混合物中的两种成分都可用作螯合剂和去污剂。制备含有这些醚羧酸盐的洗涤剂和洗衣添加剂组合物时，无需使用含磷或氮的洗涤剂增效剂成分。

  The invention relates to an electrophoretic display, comprising electrodes and cells containing at least one kind of ionic, monochrome particles, a non-polar liquid and a dispersant, wherein the ionic, monochrome particles of at least one kind are essentially aggregates consisting of a carbon containing pigment and an anionic pigment or anionic pigment derivative, and the dispersant is selected from the group consisting of polyacrylates, polyesters, polyurethanes and copolymers. In general, the whole quantity of the pigment and the main part, preferably at least 80%, most preferred from 95% to 100%, of the whole anionic pigment or anionic pigment derivative present within the cells is comprised in the aggregates, with essentially no pigment and only a minor part of the anionic pigment or anionic pigment derivative physically distinct from the aggregates.
