    摘要: The synthesis and the application of new dyes is described. In particular said new dyes can be incorporated in non-migratory state in hydrophilic colloid layers of photographic materials wherefrom they can be rapidly removed after being quickly decolorized in alkaline aqueous liquids used in the processing of said materials. In photographic applications dyes of the general formula (I) are provided with at least one ionisable group which permits solubilization in aqueous and/or alkaline medium. ##STR1## The meanings of the symbols are as defined in the claims and in the description.

    摘要: A process for preparing salts of 3-isopropyl-2,1,3-benzothia-diazin-4-one 2,2-dioxide of the general formula I ##STR1## (R.sup.1 -R.sup.4 =H, lower alkyl, lower hydroxyalkyl) by reacting bentazone (IIa) with an amine IIIa in an organic solvent, by reacting bentazone (IIa) with an amine IIIa or an ammonium salt IIIb in a virtually water-immiscible organic solvent and taking up the salt I in water or by reacting bentazone (IIa) with an ammonium salt IIIb or bentazone-sodium (IIb) with an ammonium salt IIIc, in each case in water.
