摘要:
This invention comprises dispersion comprising a solvent having dispersed therein a liquid-crystal forming dye of structural Formula I: nullD-(X)mnull-(Y)n wherein: D is a light-absorbing chromophore other than a cyanine dye or a barbituric acid oxonol dye; each Y contains an ionic or a nonionic solubilizing substituent or a group with a pKa value of less than 4 in water; each X is a nonionic substituent; n is 0 to 10; m is 0-10; and the resulting dye forms a liquid-crystalline phase in solvent. The dispersion is particularly useful in imaging and photographic elements.
摘要(中):
本发明包括分散体,其中分散有溶剂,其中分散有结构式I的液晶形成染料:在线式> [D-(X)m] - (Y) /在线式>其中:D是除花青染料或巴比妥酸氧杂菁染料以外的光吸收发色团; 每个Y在水中含有离子或非离子增溶取代基或pKa值小于4的基团; 每个X是非离子取代基; n为0〜10; m为0-10; 所得染料在溶剂中形成液晶相。 该分散体在成像和照相元件中特别有用。
