  • Patent number: 5320670
    Abstract: A bioreducible nontoxic predominantly vegetable oil paint comprising a paint base and a colorant blend is prepared which paint has a variable drying time, usually in a period of time that is longer than acrylics or watercolors but shorter than conventional oil base paints. Use of the paint is characterized by freedom from side effects caused by noxious ingredients found in conventional oil paints, ability to create the effect of either oil finished painting or watercolor and a drying time which more closely approximates the artist's application time for a single workpiece. A method making the paint and producing a watercolor-like painting from the same is disclosed.
