    • Electricallly photosensitive materials for photoelectrophoretic (PEP) imaging processes. There is a continuing effort to find materials which possess useful levels of electrical photosensitivity and exhibit good colorant properties including neutral or near neutral coloration. Symmetric or asymmetric merocyanine-cyanine-merocyanine compounds of the general formula provide these materials: wherein all moieties below are the same or different: m and n are 0,1 or 2; t and u are 0 or 1; p is 0, 1 or 2; R and R are alkyl, aryl, aralkyl, alkaryl, carbocyclic or heterocyclic or, when taken together and p is 0, are a one-or two-carbon alkylene bridge; R and R are alkyl, aryl, aralkyl, alkaryl, carbocyclic or heterocyclic; R and R are hydrogen or alkyl; R and R are hydrogen or alkyl; R , taken together with R and t is 0, and R , taken together with R and u is 0, form an alkylene or heteroalkylene bridge; R and R and R and R , taken together, form an alkylene or heteroalkylene bridge; R , R and R are hydrogen or alkyl or, taken individually together with R or R , form an alkylene or heteroalkylene bridge; Y and Y complete a basic heterocyclic cyanine dye nucleus; A and A are oxygen, sulfur, selenium or -NR wherein R is alkyl, aryl, aralkyl, alkaryl, carbocyclic or heterocyclic.
    • 用于光电泳(PEP)成像过程的电气感光材料。 继续努力寻找具有有效水平的电光敏性并显示出良好的着色剂性质的材料,包括中性或近中性着色。 通式的对称或不对称的部花菁 - 花青 - 部花青化合物提供这些物质:其中下面所有的部分是相同或不同的:m和n是0,1或2; t和u为0或1; p为0,1或2; R 1和R 11是烷基,芳基,芳烷基,烷芳基,碳环或杂环,或者当一起并且p是0时,是一个或两个碳亚烷基桥; R 2和R 22是烷基,芳基,芳烷基,烷芳基,碳环或杂环基; R 3和R 33是氢或烷基; R 4和R 44是氢或烷基; R 4与R 2一起并且t为0,R 44与R 22一起并且u为0,形成亚烷基或杂亚烷基桥; R 3和R 4以及R 33和R 44一起形成亚烷基或杂亚烷基桥; R 5,R 6和R 7是氢或烷基,或者独立地与R 1或R 11一起形成亚烷基或杂亚烷基桥; Y和Y 1完成了一个基本的杂环花青染料核; A和A 1是氧,硫,硒或-NR 8,其中R 8是烷基,芳基,芳烷基,烷芳基,碳环或杂环。
