Reactive Dyes Containing Halobenzene Nucleus. II.

Reactive dyes with a general formula, or -SO2 CH3 were synthesized (D=dye component, D-NHSO2 and -CF3 or -SO2CH3 are in o- or p-position to fluorine atom) by condensation of azo, anthraquinone or phtha-locyanine type dyes having amino group capable of acylation with 3 kinds of following sulfonyl chlorides : These dyes can be combined chemically with cotton, nylon, silk, wool, etc., by heating with alkali to make fast dyeing against washing, but the reactivity of fluorine of these dyes was weaker than that of D-NHSO2type dyes and the dyeing ability was poorer. However the light-fastness of dyed product was better than that with the above nitro type dyes.
