The experimental part has involved the following: - synthesis of 2-aminobenzohiazoles 6-substituted with methyl, methoxy, chloro, nitro and SO3H groups and synthesis of a new class of acid benzothiazole dyes containing sulphonic groups; - physical-chemical characterization of the resulted products; - application of the acid benzothiazole dyes in leather and woolen skin dyeing and objective assessment of their colours by means of a colour measurement software. Solubility of the 2-aminobenzohiazoles 6-substituted with -CH3, -OCH3, -Cl, -NO2  groups was increased when these were sulphonated with fuming sulphuric acid containing 22-24 %  SO3, resulting in blends of two isomers 4 and 5 of sulphonic acid with  -CH3, two isomers 5 and 7 of sulphonic acid with  -OCH3, and of three isomers  with –Cl, and a single product with -SO3H in position 4 for the –NO2 substitute. These products were the diazotizable constituent to obtain 4 series of benzothiazole dyestuffs by coupling with 12 coupling constituents, resulting in 52 benzothiazole dyestuffs of increased water solubility which can be used in bath dyeing of the protein supports like as leather and furs. The colours of the dyed furs were assessed by an own software – COLORINDEX.
