The preparation of dye-containing compositions, in which the dye is copolymerized with an acrylic based monomer, is disclosed. A hydrophilic copolymer is formed in which the dye is present 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 microspheres.
