Phthalocyanine reactive dyes e.g. for cellulose - with sulpho-benzyl-sulphamoyl gp. substd. by 4-amino-6-fluoro-s-triazinyl-2-amino gp.

摘要

reactice dyes of formula (I) are new: (where Pc is a phthalocyanine radical; A is H or opt. substd. alkyl; R1 and R2 are H or opt. substd. alkyl, cycloalkyl or aryl, or R1+R2 is alkylene opt. interrupted by heteroatoms; Y is NR3R4 or NHR5; R3 is H or opt. substd. alkyl or aryl and R4 is opt. substd. alkyl, or NR3R4 is a ring opt. contg. another heteroatom; R5 is H or substd. aryl; a = 0-2; b = 1-3; c = 1-3; a+b+c =4). (I) are useful for dyeing and printing cellulosic materials (e.g. natural or regenerated cellulose) and amide-contg. materials (wool, silk or synthetic polyamides). They give strong, mainly turquoise shades with good fastness, esp. to light and wet processing.
