Patent number: 8148312Abstract: The invention provides an aqueous bleaching solution for substrate treatment comprising a source of oxidant and a suspended polymer matrix having a plurality of optically functional particles associated with one or more copolymers present in the polymer matrix. The plurality of optically functional particles are associated with the copolymer during polymerization of at least one hydrophobic and at least one hydrophilic monomer so as to form a polymer matrix useful to impart an aqueous bleaching solution with optically functional properties providing a benefit to the solutions during storage, use and application to substrates for treatment.Type: GrantFiled: September 20, 2011Date of Patent: April 3, 2012Assignee: The Clorox CompanyInventors: Thomas W. Kaaret, Darin K. Griffith, Klein A. Rodrigues, William L. Smith
