    摘要： Polymeric dyes of the present invention have the formula: ##STR1## wherein Me represents the methyl group, x can range from 2 to 100, y can range from 20 to 300, and the ratio of x:y is at least 1:10 and is preferably from 1:5 to 1:1. The symbol L represents the divalent group which connects the chromophoric moiety and the polysiloxane moiety together by covalent bonds. L is conveniently a saturated divalent aliphatic group which connects the silicon atom to the chromophoric group by a non-hydrolyzable covalent bond. Chromo represents an aromatic chromophore which imparts color to the polymer molecule. The polmeric dyes of the present invention can be used to dye natural fibers such as silk, wool, and cotton and to color plastics such as nylon, Dynel, Acrilan, acetate, and viscore. In addition, the polymeric dyes can also be used as a food dye when water soluble groups are present (e.g., on the chromophores) to impart water solubility to the polymeric dye. Because of the stability and the high molecular weight of these polymeric dyes, they can be used as colorants for food as well as in pharmaceutical and cosmetic applications.

    摘要翻译： 本发明的聚合染料具有下式：其中Me表示甲基，x可以在2至100的范围内，y可以在20至300的范围内，x：y的比例至少为1:10， 优选为1：5〜1：1。 符号L表示通过共价键将发色部分和聚硅氧烷部分连接在一起的二价基团。 L方便地是通过不可水解的共价键将硅原子与发色基团连接的饱和二价脂族基团。 色度表示赋予聚合物分子颜色的芳族发色团。 本发明的聚酰胺染料可以用于染色天然纤维如丝，羊毛和棉花，并且可以使塑料如尼龙，Dynel，Acrilan，醋酸酯和粘胶染色。 此外，当存在水溶性基团（例如在发色团上）时，聚合染料也可以用作食品染料，以赋予聚合染料水溶性。 由于这些聚合染料的稳定性和高分子量，它们可以用作食品以及制药和化妆品应用中的着色剂。

    摘要： A process for preparing a family of orange polymeric colorants having a plurality of units of the chromophore ##STR1## is disclosed. R.sub.1 and R.sub.2 are hydrogens, lower alkyls or alkoxies, nitros, halos or sulfonates, R.sub.3 is benzyl, benzyl sulfonate, lower alkyl or alkyl sulfonate, R.sub.4 is hydrogen or lower alkyl. With the disclosed process, the chromophore units, less the R.sub.3 substituent, are bonded to an organic polymer backbone. The R.sub.3 substituent is added thereafter in a separate second step.
