摘要: Water-soluble benzylated polyamidoamines which contain from 0.1 to 0.9 mole of benzyl groups per equivalent of nitrogen, and onto which from 20 to 400 parts by weight of ethyleneimine or propyleneimine have been grafted per 100 parts by weight of polyamidoamine, processes for the preparation of the materials, and the use of the materials as cationic assistants in processes for coloring paper with acid dyes and/or direct dyes in an aqueous medium. The papers obtained show a high color strength, with substantially no two sidedness of the coloration.

摘要: A process for removing anionic compounds from water which is recycled in manufacturing processes, and from waste water, by adding (1) water-soluble products obtained by reacting an alkylating agent, having an aromatic substituent, with a cationic polyelectrolyte and (2) mineral adsorbents and/or a magnesium salt, aluminum salt or iron salt, with formation and flocculation of water-insoluble reaction products.

摘要: A process for coloring paper with an acid dye and/or direct dye in an aqueous medium in the presence of a water-soluble reaction product of an alkylating agent, possessing an aromatic substituent, with a cationic polyelectrolyte.The process gives papers with high color strength and substantially avoids cylinder twosidedness of the coloration.
摘要翻译: 在具有芳族取代基的烷基化剂与阳离子聚电解质的水溶性反应产物的存在下,在含水介质中用酸性染料和/或直接染料着色纸的方法。 该方法提供了具有高色强度的纸张,并且基本上避免了着色的圆筒形二次。
