Abstract

1333937 Cationic dyestuff solutions CIBAGEIGY AG 4 Nov 1970 [5 Nov 1969 20 Feb 1970] 52531/70 Heading D1B The invention comprises storage-stable acidic solutions of cationic dyes of the benzo 1, 2- pyrane series, the cation being free from substituents producing an acid reaction on dissociating in water, in a solvent which comprises a water-soluble organic base, a watersoluble carboxylic acid, water, and optionally one or more neutral organic solvent. The solutions preferably contain by weight of the total solution 15 to 40% of dye salt, 25 to 60% of water-soluble carboxylic acid, 20 to 60% water and 3 to 15% of water soluble organic base, and the amounts of acid and base are such that after dilution with water 5 to 40g solution/litre water gives a pH of 3.5 to 5. The water-soluble organic bases used include primary, secondary and tertiary alkylamines (includes hydroxyalkylamines) aminoalkylamines, cycloalkylamines, aralkylamines, heterocyclic amines, urea and its N, N'-substituted derivatives. The water-soluble carboxylic acids includes C 1 -C 4 aliphatic monocarboxylic acids and hydroxycarboxylic acids. The optional neutral organic solvents include aliphatic alcohols and their ethers, esters, ketones, hydroxyketones, amides, nitriles, dialkylsulphonides, lactones, sulpholenes and sulpholanes. Other adjuvants include metal complex forming agents and non-ionic stabilisers. The solutions are stable in storage and on dilution are used for the printing or dyeing of leather, wool, silk, cellulose acetate, tannined cotton, paper, acid modified polyamide, polyurethane, polypropylene, polyesters and especially polyacrylonitrile.
