The foam is applied by applying to the cellulose material a foamed, aqueous preparation which contains in addition to dyes and fixing alkalis(1) a foam-forming agent(2) a homopolymer or copolymer of acrylamide or methacrylamide or preferably a graft polymer which is obtained from an addition product of an alkylene oxide, preferably propylene oxide, on an at least trihydric aliphatic alcohol, e.g. glycerol, and acrylamide or methacrylamide, and(3) a betainelike quaternary ammonium salt which is obtainable by condensation of (A) a sulfonated asymmetric succinic acid diester which has as ester groups a halohydrin group and an etherified polyalkylene glycol group, with (B) a tertiary amine-substituted N-alkylamide of ethylenically unsaturated aliphatic monocarboxylic or dicarboxylic acid.The cellulose material thus treated is then subjected to a heat treatment, for example steaming, to fix the dye.Type: GrantFiled: February 22, 1988Date of Patent: December 20, 1988Assignee: Ciba-Geigy CorporationInventors: Hans-Ulrich Berendt, Martin Kuhn
