Zusammenfassung:	Metal dye 1:2 complexes in the form of Li salts are claimed. Also claimed are conc. solns. contg. Li salts of these complexes, OH gp-contg. org. solvents and opt. water and a process of prepg. Cr dye 1:2 complexes based on azo and azomethine dyes by chromating metallisable dyes in OH gp-contg. org. solvents in the presence of basic Li salts with Cr acetate or formate. The concentrates are storage stable and can be mixed with a large amt. (=50%) of water without precipitating the dye. Dye concn. may be as high as 40% and storage temp. as low as -15 degrees C. Used in dye baths and printing pastes for dye/printing N-contg. fibres (wool, silk, feather) as well as polyurethanes and polyamides.
