ABSTRACT:
The present invention is directed to novel amino-substituted 2-cumaryl-3'-chromenylium salts of the general formula ##STR1## wherein R.sup.3 and R.sup.7 are a dialkyl or cycloalkyl disubstituted amino group, hydrogen, or hydroxy group, provided that at least one of R.sup.3 and R.sup.7 is an amino group, R.sup.1, R.sup.2, R.sup.4, R.sup.5, R.sup.6, and R.sup.8 are hydrogen, an alkoxy group, or two of these substituents together form an aromatic ring, provided that R.sup.1, R.sup.2 and R.sup.4 may be the same or different, and R.sup.5, R.sup.6 and R.sup.8 may be the same or different, and Y.sup.- is an acidic anion and to the process for their preparation.
