| titleOfInvention | Process for the production of khaki dyeings or prints using azo dyestuffs |
| abstract | Khaki prints are obtained using a paste containing a dyestuff made by coupling diazotized 1 - amino - 2 - methyl - 5 - nitro - or - 2,5 - dihalogenobenzene with 1 - (31 - hydroxydiphenylene oxide - 21 - carboylamino) - naphthalene and Example (2) describes a paste prepared from the diazo component 1-amino2,5-dichlorobenzene, an aqueous emulsion of a copolymer of vinyl acetate and butyl acrylate, an ammoniacal solution of a condensation product from urea, formaldehyde and ethylene glycol, tragacanth thickening and ammonium hydroxide and thiocyanate solutions. Specification 426,564, [Group IV], is referred to.ALSO:In a dyeing or printing process a dyestuff is used which is obtainable by coupling diazotized 1 - amino - 2 - methyl - 5 - nitro - or - 2, 5 - dihalogeno - benzene with 1 - (31 - hydroxydiphenylene oxide - 21 - carboylamino) - naphthalene. Khaki dyeings or prints are produced on fibrous materials especially those composed of vegetable fibres, e.g. cotton and viscose, which give infra-red photographs exhibiting effects similar to those of chlorophyll and may thus be used for camouflage purposes. In examples (1) a cotton fabric is impregnated with a solution containing 1 - (31 - hydroxydiphenylene oxide - 21 - carboylamino) - naphthalene, soda - turkey red oil, alcohol and caustic soda and the dried fabric is treated with a solution of a stable diazonium compound of either of the above amines adjusted with partially dehydrated aluminium sulphate (and also sodium naphthalene - 1,6 - disulphonate when the 5 - nitrobenzene derivative is used) passed through air at 30 DEG C. and sodium carbonate solution then rinsed and soaped at the boil and in (2) the coupling component in aqueous caustic soda solution containing ethanol is treated with diazotized 1 - amino - 2,5 - dichlorobenzene, the dyestuff isolated and made into a printing paste for cotton or viscose containing an aqueous emulsion of a copolymer of vinyl acetate and butyl acrylate, ammoniacal solution of a condensation product from urea, formaldehyde and ethylene glycol, tragacanth thickening and ammonium hydroxide and thiocyanate solutions. The dyestuffs may also be produced on the fibre by usual printing processes such as those using an antidiazotate or a water-soluble diazoamino compound of one of the two amines together with the azo component with subsequent colour development or the naphtholate or base printing process may be used. Specification 426,564 is referred to. |
