DYE FIXATION BY COPOLYMERIZATION

摘要

The preparation of dye - containing compositions, in which the dye is copolymerized with an acrylic bared monomer, is disclosed. A hydrophilic copolymer is formed in which the dye is prevent in a nondiffusible form. The dye - acrylic polymer composition can be produced in the form of microbeads by emulsion polymerization In addition, light scattering particles may be added in the form of a material such as polystyrene microrpheres.
