The reaction of azomethine dyes (1a - g) with malonodinitrile (2) gives dicyanomethylene-pyrazolin-5-one (4) which immediately reacts with the eliminated anilines by HCN-amine exchange giving the deeply coloured arylamino-cyanomethylene-pyrazolinones (5a-g). Structural investigations and a study of the absorption characteristic are described.
