Abstract: Novel 1-(4''-methoxysulphonyl-phenyl)-3-(4''''chlorophenyl)pyrazoline is described which has unexpectedly a very good affinity to cellulose ester fibers and optically brighten these fibers in pure white, free from undesirable greenish or greenish-blue hues even when applied in higher concentrations; compositions containing this novel compound as well as other substances, especially detergents, are also described; and a process for optically brightening cellulose ester and particularly cellulose acetate fibers is also disclosed.
