Patent number: 4877413Abstract: The invention relates to a process for the end-to-end dyeing of cellulosic materials, or blends that contain cellulose, with direct and/or reactive dyes by the pad dyeing process, which comprises using an aqueous liquor that contains at least one water-soluble direct or reactive dye and at least one water-soluble anionic, colorless organic compound having an affinity factor A, at a concentration of 0.2 to 0.3 g/l, for mercerized cotton of 1.1 to 4, said factor A being the quotient of the concentration of the water-soluble, colorless organic compound in a liquor without addition of dye, before impregnation, divided by the concentration of the water-soluble, colorless organic compound in the residual liquor without dye after impregnation. The process of this invention is suitable for dyeing textile cellulosic materials or blends containing cellulose to give end-to-end dyeings of good fastness properties.Type: GrantFiled: March 26, 1987Date of Patent: October 31, 1989Assignee: Ciba-Geigy CorporationInventors: Jean-Marie Sire, Peter Scheibli

Patent number: 4854934Abstract: They have the formula: ##STR1## where either R.sub.1 and R.sub.2 are identical and represent --CH.sub.2 R where R=H or a C.sub.1 to C.sub.4 alkyl group or R.sub.1 and R.sub.2 together form the --CH.sub.2 (CR.sub.4 R.sub.4).sub.n --CH.sub.2 group where n=0 or 1, R.sub.4 =H or --CH.sub.3, R.sub.3 =H or --CH.sub.2 R.sub.5 where R.sub.5 =H or a C.sub.1 to C.sub.4 alkyl group. A and A.sub.1 are either identical and represent H or A and A.sub.1 together form an ethylene, trimethylene or --CH(OCH.sub.2 R.sub.6)--CH(OCH.sub.2 R.sub.6)-- radical where R.sub.6 =H or a C.sub.1 to C.sub.4 alkyl group or, when R.sub.3 =H, a 1,2 dihydroxy-ethylene group.They are obtained by reacting a disubstituted ethanal ##STR2## with a urea ANH--CO--NHA, followed if required by etherification with an alcohol R.sub.5 CH.sub.2 OH.Type: GrantFiled: March 14, 1988Date of Patent: August 8, 1989Assignee: Societe Francaise HoechstInventors: Didier Wilhelm, Antonio Gelabert, Alain Blanc
