    摘要: Dyed raw cellulose can be bleached in a bleaching and after-treatment bath containing, in addition to usual stabilizers, cationic-monomeric and/or polymeric compounds and, if desired, nonionic surfactants. Bleaching is carried out with the aid of aqueous-hydrogen peroxide. The stabilizers that can be used and the cationic compounds are defined in the specification. Nonionic tensides, if their co-use is desired, are those of the class polyglycolethers.

    摘要: Aqueous pigment dispersions which contain organic or inorganic pigments and water-soluble oxalkylation products of compounds which are obtainable by condensation of aromatic compounds, containing phenolic OH groups, or their ethers, especially lower alkyl ethers, with formaldehyde and amines which contain at least 2 NH groups which are reactive towards formaldehyde, or derivatives of such oxalkylation products are suitable for pigmenting natural or synthetic materials.
