Abstract

351,220. Electrolysis. BENSA, F., 6A, Via Serra, Genoa, Italy. June 6, 1930, No. 17555. Convention date, July 16, 1929. [Class 41.] Vat dyestuffs; producing.-A vat dyestuff, dyeing cotton in violet shades, is made by subjecting 3 : 9-dibenzoylperylene to electrolytic treatment in a suitable solvent, preferably concentrated sulphuric acid. An example is given. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the production of vat dyestuffs by electrolysis from perylene diketones in general. This subject-matter does not appear in the Specification as accepted.
