Films obtained from paints based on conventional aqueous polymer dispersions exhibit improved wet adhesion to alkyd resin-coated substrates and improved blocking resistance if the paints contain polyglycidylamines which carry 2 or more glycidyl groups which are bonded to hydrogen-free nitrogens.

Aqueous paints which contain polyglycidylamines as additives

An improved process for dyeing or printing water-swellable cellulosic fibers and mixtures of said cellulosic fibers with synthetic fibers by contacting the fibers throughout with a dye liquor or print paste which contains, as essential ingredients, water in an amount sufficient to swell the cellulosic fibers, a water-insoluble disperse dye and a water-soluble solvent which maintains swelling of the cellulose if water is removed and which is a solvent for the disperse dye, and heating the contacted fibers to effect fixation of the dye, the improvement comprising using as water-soluble solvent a mixture of
