<p>Binding agents, or fixatives, are prepared in granular form by mixing with a dispersing agent e.g. one or more condensation products of ethylene oxide with long chain fatty alcohols, fatty acids and/or fatty amides, condensation products of ethylene oxide with phenols, which may be substituted with one or more alkyl groups, sulphated and/or sulphonated fatty alcohols, substituted benzene and/or naphthalene, gelatine, dextrins, sodium alginates, one or more fatty acid esters with long fatty acid chains of polyglycols, polyvinyl alcohols, ethyl cellulose and/or copolymers of maleic acid anhydride. The material is allowed to harden. The method is useful for preparing dyes in granular form.</p> |
