摘要:
A new class of dyestuffs that contains a carbamate structure to which there is attached an N-hydroxymethyl group has been prepared. These new dyestuffs were prepared through combination of certain dyestuffs with the hydroxyl group of hydroxyalkyl carbamates. Methylolation of the carbamate moiety renders the dyestuffs reactive under acidic conditions to cellulosic and other textile materials containing reactive hydrogens.
摘要:
A method for preparing a polymerizable monomer-dye compound is provided in which a monomer, a reactive dye, and base are combined under substantially anhydrous reaction conditions to form the polymerizable monomer-dye compound, wherein the monomer comprises a pendant reactive group that covalently links to the reactive dye to form the monomer-dye compound.
