<p>Propylene oxide reaction products, and the salts or quaternization products thereof are provided which are obtained from (a) an at least trihydric aliphatic alcohol of 3 to 10 carbon atoms, (b) 1,2-propylene oxide, (c) an aliphatic dicarboxylic acid of 2 to 10 carbon atoms, an aromatic dicarboxylic acid of 8 to 12 carbon atoms or the anhydrides thereof, and at least one of the following components: (d) an aliphatic diol with a molecular weight of at most 2000, (e) a fatty alcohol containing 12 to 22 carbon atoms, (f) a fatty acid containing 12 to 22 carbon atoms, and (g) an aliphatic monoamine or diamine containing 2 to 12 carbon atoms, of which component (g) is used only at the conclusion and only if component (c) is ethylenically unsaturated. The inventive products are suitable for widely varying uses in textile finishing. In particular they are used as printing and dyeing assistants, for example, to improve the fastness properties of dyeings, to prevent the bleeding of non-dyed or non-printed areas during the washing-off process of these dyeings or prints, or to prevent the deposition of oligomers on the textile material during the high temperature dyeing of polyester fibres.</p> |
