Abstract
A method of providing for manufacturing a colored polymer resin having the steps of: (a) blending a disazo colorant into a mixture of monomers, the colorant having a poly(oxyalkylene) substituent comprising from 2 to 200 alkylene oxide residues, bonded to each end of the disazo chromophore, the poly(oxyalkylene) substituent having a nucleophilic terminal group which is capable of reacting with at least a portion of the monomers; (b) providing conditions under which the monomers and disazo colorant polymerize to form a colored polymer resin.
