Abstract

The oxidation products of "ketonic perylenes," or their reduced derivatives, described in the parent Specification, are alkylated by means of the alkyl esters of p-toluenesulphonic acid; the process may be carried out in aqueous suspension. According to examples, the oxidation products of dibenzanthrone or isodibenzanthrone, or their reduced derivatives, are methylated or ethylated; the products dye green, blue, and turquoise shades. Specification 181,304 is referred to.
