Process for dyeing cellulosic textile fibre materials

A process for dyeing and finishing cellulosic textile fibre material in one step, which process comprises applying to said textile fibre material by pad dyeing methods a liquor comprising

• (A) at least one reactive dye suitable for dyeing cellulosic materials,
• (B) a crosslinking agent for improving creasing and shrinkage, wherein the crosslinking agent is a glyoxalurea derivative, a melamine/formaldehyde condensate which may be partially or completely etherified, or a N-methylolurea compound which may be partially or completely etherified,
• (C) a crosslinking catalyst for anticrease and antishrinking finish, wherein the crosslinking catalyst is an inorganic acid, a Lewis acid, an ammonium salt or the hydrohalide of an organic amine, and
• (D) choline and subsequently fixing the dye on the textile fibre material.
