Abstract

<FORM:0663190/IV (a)/1> A colour coupler is prepared by boiling together in pyridine 6-aminoindazolone hydrochloride and styrene-maleic anhydride copolymer. The compound has the formula shown in Fig. XIII, where x is a positive integer.ALSO:5 : 7-Dichloroindazolone is prepared by adding aqueous sodium nitrite to an aqueous hydrochloric acid solution of 3 : 5-dichloro-2-aminobenzoic acid, adding the mixture to an aqueous saturated solution of SO2 while passing SO2 into the solution, and boiling. Indazolone-5-sulphonic acid and 5-methylene-bis-(indazolone) are similarly prepared. 6 - (21 - benzthiazolylamino) - indazolone is prepared by evaporating an ethanol solution of 6-aminoindazolone hydrochloride and 2-chlorobenzthiazole. 6 - (11 - Methylbenzthiazolylidene - 21) - aminoindazolone is prepared by refluxing together 6 - aminoindazolone hydrochloride, 2 - methylmercaptobenzthiazole dimethyl sulphate, and pyridine. 6 - Phthalimidoindazolone, 4-, 5-, 6-, and 7 - octadecenylsuccinylaminoindazolone, and 5-stearoyl-indazolone are similarly prepared. 6 : 7-Imidazoindazolone is prepared by coupling 6-aminoindazolone with diazotized sulphanilic acid, reducing with stannous chloride and hydrochloric acid, and boiling with anhydrous formic acid and fused sodium acetate.
