ABSTRACT:
Cationic fluorescent whitening agents of the formula ##STR1## wherein B is a fluorescent whitening agent containing basic tertiary amino groups, m is the number of basic amino groups, and each of R.sub.1, R.sub.2 and R.sub.3 is alkyl of 1 to 4 carbon atoms which is unsubstituted or substituted by non-chromophoric groups, or is alkenyl of 2 to 4 carbon atoms which is unsubstituted or substituted by non-chromophoric groups. These compounds have good solubility in water and they make it possible to prepare concentrated solutions and can be used for whitening organic material.
