摘要： Phthalocycanine reactive dyestuffs corresponding to the formula

wherein Pc represents the radical of a phthalocyanine, R1 and R2 are hydrogen, or identical or different alkyl radicals which may be cyclized and/or further substituted, or they are optionally substituted cycloalkyl, aralkyl or aryl radicals; R3 represents hydrogen, an alkyl radical with 1-5 carbon atoms, which may be substituted by water-solubilizing or by not water-solubilizing groups, or a cycloalkyl radical; R4 and R5 are hydrogen or lower alkyl radicals; A is hydrogen or a substituent; Y is the group SO2-CH2-CH2-OSO3H, -SO2-CH CH2, -SO2-CH2-CH2-S-SO3H; a is a number from 0 to 3, b is a number from 0 to 2, and c is a number from 1 to 4, the sum total of a, b, and c not exceeding 4. The dyestuffs of this invention are useful in dyeing wool, silk, leather, linear polyamides and particularly cellulose, containing fibrous materials such as linen, regenerated cellulose, and cotton.
