Patent number: 4363887Abstract: There is disclosed a water-in-oil emulsion enamel composition having water dispersed in an organic solvent soluble resin and solvent, and having the polar enamel pigment dispersed through the use of titanium derived coupling agents. Amine salts of pyrophosphato titanium derived coupling agents act as pigment dispersants and as the water-in-oil emulsifying agent. The composition may be mixed with a hydrocarbon propellant miscible in the continuous phase in suitable containers to produce a water containing aerosol spray enamel.Type: GrantFiled: June 11, 1981Date of Patent: December 14, 1982Assignee: Seymour of Sycamore, Inc.Inventor: Gus W. Leep

Patent number: 4362838Abstract: There is disclosed a high gloss sag resistant water-in-oil emulsion coating composition having water dispersed in an organic solvent soluble resin and a solvent blend having a boiling range and a progression of boiling points which allow a high gloss, sag-free coating to be formed from a water containing paint. The composition may include colloidal hydrated aluminum silicate to further assist in the evaporation of the dispersed water in the formation of the high gloss film.Type: GrantFiled: June 11, 1981Date of Patent: December 7, 1982Assignee: Seymour of Sycamore, Inc.Inventors: Gus W. Leep, Gary L. Bolt

Patent number: 4327006Abstract: A writing liquid is formed from a solvent for an organic styrene resin pigment in combination with a chlorofluoroalkane of from 1 to 3 carbon atoms. The potential toxicity of the solvent (or solvent vapors) is eliminated and writing speeds of the writing liquid are improved by the addition of the chlorofluoroalkane. The writing liquid is used for transparentizing an opaque layer of an organic styrene resin pigment, uniformly distributed as fine particles in a film-forming binder carried on a transparent or opaque support. When the writing liquid is applied to the opaque layer using a suitable writing instrument, such as a pen, the opaque layer immediately becomes transparent where it is contacted with the solvent.Type: GrantFiled: September 2, 1980Date of Patent: April 27, 1982Assignee: La CellophaneInventor: Claude Ceintrey
