Also'in the specification of co-pending U. S. application S. N. 758,468, filed July 1, 1947 now issued as U. S. PatentNo. 544,825.- of' March 13; 1951, a: process is describedsfor. making-dyestuffs. of the anthraquinone series-.andzrelated'polycyclic. ketone types, for example; dyestufis-ofthe. acedianthranone, dibenZ- anthrone; isodihenzanthrone, indanthrone, and
perylene tetracarboxy,-;di1(pheny1imide) series which. contain similarsalti groups attached through methylene linkages toaromatic nuclei.
We have now found that dyestufi's of the above kind which we call "-onium dyestuffs are of exceptional value for application tofibrous materials, particularly textile materials and paper, by printing and other local colouration processes.
We have also found'thatsuch dyestuffs can be applied by padding-processesgandjthat'when textilematerialor paper whichhas; previously been printed with resists, is padded with a solution of "onium" dyestuff, thedyfistwu fu is applied to the nresisiediportionspi the.- material orpaper and valuable: local.- cclcuration .eiffectsare obtained,

Among the other many combinations by which novel and useful effects can be obtained there may be mentioned:
(1) Padding with an alkaline solution of a 2:3- hydroxynaphthoic arylamide, printing in succession with (a) an onium dyestufl, (b) an acidic paste containing a stabilised diazo compound, (c) an acidic white resist and subsequently padding with a solution of a stabilised form of a second diazo compound, which diazo compound does not couple under acidic conditions for example Brentamine Fast Blue VB salt.

(3) Printing in succession with (a) an onium dyestuif, (b) a zinc oxide while resist, (c) a vat dyestufi and zinc oxide and then padding with a solution of a leuco sulphuric ester derivative of a vat dyestuif and developing.
(4) Printing with a white resist and then with one or more pastes containing a stabilised diazo compound and a wax thickening mixture, on a textile material which has previously been padded with an alkaline solution of a 2:3-hydroxynaphthoic arylamide and dried, drying and padding with an onium dyestufl solution.
(5) Printing with a paste containing a stabilised azoic combination and a parafiin wax emulsion, acid steaming, drying, and then padding with a solution of an onium" dyestuff.
(6) Printing with a paste containing a vat dyestuil, a wax resist, an alkali and a. reducing agent, drying and then padding with a solution of an onium dyestuff.
