Organic Colorant Complexes from Reactive Dyes and Articles Containing the Same

An organic colorant complex with the following general structure (I):

• ABn(DE)mTxQy (I)
• wherein
• A is an organic chromophore selected from an azo, phthalocyanine or anthraquinone chromophore group;
• B is an electrophilic reactive group selected from monochlorotriazine, monofluorotriazine, dichlorotriazine, sulfatoethyl sulfone, vinyl sulfone, 2,3-dichloroquinoxaline, and 2,4-difluor-5-chloropyrimidine groups and is covalently bonded to A directly or through a linking group;
• D is a nucleophilic linking group covalently bonding B and E, selected from NR, O, S, and 4-oxyanilino (—HN-Ph-O—);
• wherein R is H, alkyl, aryl or E;
• E is an organic moiety or an end group;
• T is a cationic quaternary ammonium group covalently linked to A;
• Q is a counterion, bonded to the organic chromophore through ionic interaction with T;
• and
• n, m, x, and y each independently are integers of 1-10.
