Abstract (en)
[origin: EP0342517A2] Use of 3-aminoreductones of the formula I <IMAGE> in which R<1>, R<2> and R<3> are identical or different and hydrogen, methyl or ethyl and R<4> stands for a straight-chain or branched alkyl or alkenyl group having 1 to 20 C atoms, which can be substituted by one or more hydroxyl groups, alkoxy groups having 1 to 3 C atoms in the alkyl radical or acetoxy groups, or a radical -(CH2-CH2-O)nH, in which n stands for the numbers 1 to 10 and which can be etherified with an alkyl radical having 1 to 3 C atoms or esterified with an acetyl radical, or R<4> together with the N atom forms the radical of an aliphatic alpha - or beta -amino acid having 2 to 15 C atoms, it being possible for the carboxyl group present to be neutralised as the alkali metal, alkaline earth metal or ammonium salt or esterified in the form of a C1- to C10-alkyl ester, or their mineral acid salts as discharge agents for disperse dyes in the printing of polyester, triacetate, acetate or polyamide textile materials or their mixtures with one another by the discharge or discharge resist process.
