Patent number: 6586051Abstract: Improvements for in-mold polyurethane foam and/or resin products and the ability to provide surface coatings of such products exhibiting bright coloration and reduced colorant migration through utilization of easy-to-use polymeric colorants in simplified and environmentally friendly processing methods are disclosed. The inventive surface coating formulations include polyurethane-reactive polymeric colorants admixed with prepolymer and excess amounts of certain isocyanate compounds. Such a composition is applied (by spraying, for example) to a polyurethane prepolymer (for the production of the internal polyurethane article) which is then introduced within a mold in order to form a particularly shaped or configured polyurethane article with a colored surface coating. Upon curing through exposure to heat, the coating composition reacts with the introduced polyurethane prepolymer to form a surface over the target internal polyurethane.Type: GrantFiled: April 24, 2002Date of Patent: July 1, 2003Assignee: Milliken & CompanyInventors: Zhaolin Zhou, Rubin Cai

Patent number: 6417155Abstract: Colored detergent bars are provided comprising water soluble polymeric colorants that exhibit excellent non-staining performance on fabrics and other contacted surfaces, including manufacturing and/or washing equipment, are easy to process into the desired detergent bar compositions, and do not exhibit any appreciable harmful effects to the environment. The particular polymeric colorants utilized in this respect are of very high molecular weight (in order to assure staining will not occur on target cleaning surfaces), are extremely water soluble, provide excellent vivid and aesthetically pleasing color shades within the target bar compositions, and are present as liquid or waxy pastes at room and at processing temperatures. The ultimate laundry bar product thus exhibits highly pleasing colors for product distinction as well as for aesthetic purposes.Type: GrantFiled: September 15, 2000Date of Patent: July 9, 2002Assignee: Milliken & CompanyInventors: Zhaolin Zhou, Tiong Khoon Ong
