The treatment of cobalt phthalocyanine‐3, 3′, 3″, 3′″‐tetrasulphonylchloride with different primary amines with different substituents has given eight novel cobalt phthalocyanine‐3, 3′, 3″, 3′″‐tetrasulphonamide compounds. The structure determination have been carried out using elemental analysis, molecular weight measurements and infra‐red spectroscopy. Direct application of the new synthesised dyes to cotton and viscose fabrics at two different bath concentrations gave a range of percentage reflectances values in the visible region. The absorption maxima appeared in both cases in the range 670–680 nm.
