Abstract
A process for dyeing or printing an article comprising a hydrophobic polymer, wherein the hydrophobic polymer is brought into contact with a condensation polymer obtained by condensation of at least one poly-hydroxyl-mono-carboxylic acid, prior to or simultaneously with the treatment of the article with a color imparting compound, with the proviso that the condensation polymer is not terminated with lipophilic groups. The process provides dyed articles with good fastness properties.
