The invention concerns hair dyes that contain dicyanmethylene indane derivatives and optionally substances selected from the group of (a) primary and secondary aromatic amines, hydroxydes, nitrogen-containing heterocycles; (b) amino acids; (c) 2-9 amino acid-containing oligopeptides; (d) CH-acids; (d) aryl or heteroaryl aldehydes or ketones; (f) quaternary ammonium compounds Thus in a hair dyeing experiment 5 mmol 1,3-bis(dicyanmethylene)-indane, 5 mmol 4-dimethylaminobenzaldehyde were mixed with 5 mmol sodium acetate in 50 mL water at 50°C; pH 9 was set and the solution was used to dye hair; intense blue color was obtained. The experimental process involved the reaction of 2-(2,3-Dihydro-1H-inden-1-ylidene)malononitrile(cas: 2510-01-2).Related Products of 2510-01-2
