Abstract
Abstract The invention provides reactive dyes of the formula ##STR1## wherein Pc is the radical of a copper or nickel phthalocyanine, X is a substituted or unsubstituted amino group, A is an alkylene or arylene radical, Y is a removable or non-removeable substituent, W is sulfo or carboxyl, and Z is a reactive radical, and a, b and c are whole or fractional numbers, with the proviso that each of a and c is at least 1, b is a value between 0 and 2 and the sum of a+b+c must be 4.
