Patent number: 6743756Abstract: Liquid suspensions of particles in non-aqueous solvents are extremely stable over long periods of time with minimum separation of the solvent and no hard packing of the dispersed particles. The suspensions enable a user to rapidly add the suspension to water and to mix at low speeds without generating fugitive dust in the process. In addition, a liquid dispersion can provide an easy to use liquid containing higher concentrations of the active dispersed phase than can be accomplished by simply preparing an aqueous solution of the dispersed phase. Alternatively, highly water-soluble particles may also be suspended which have poor storage, freeze/thaw, or heat/cool stability. In some cases, liquid dispersions can yield controlled release of the dispersed phase because the dispersed phase is not in aqueous solution. The suspensions are environmentally safe and biodegradable and may be used in environmentally sensitive applications, such as for oil well treating fluids for offshore areas.Type: GrantFiled: July 13, 2001Date of Patent: June 1, 2004Assignee: Benchmark Research and Technology, Inc.Inventor: William Franklin Harris, Jr.

Patent number: 6020405Abstract: Phase change (hot melt) ink compositions for use in a phase change (hot melt) ink jet recording device are disclosed to comprise:(a) from about 0.1% to about 30% of one or more colorants; and(b) from about 0.1 to about 99.9% of one or more reversibly-crosslinked-polymers.Recording is conducted by thermally melting the ink at a temperature above ambient temperature (20.degree. C.) to provide prints that possess high quality images, scratch resistance, abrasion resistance, low-temperature storage stability and flexibility, offset and pick resistance, adhesion, and other desired properties. Components other than those listed above may be included in the ink compositions to achieve specific printer, substrate, or end use requirements. Furthermore, the present invention also includes methods for the preparation of the above-described inks.Type: GrantFiled: May 8, 1998Date of Patent: February 1, 2000Assignee: Westvaco CorporationInventors: Michael D. Matzinger, Robert P. Rodebaugh
