  • Patent number: 4717620
    Abstract: A multitone or multicolor decorative, textured coating on a substrate comprises rigid, spheroidal polymeric beads distributed in a random pattern and embedded in a coherent coating film comprising a film-forming polymer. The beads may be colored and are of a defined size relative to the coherent coating film thickness and there is a contrast in tone or color between the coherent coating film and at least some of the beads. The coating is obtained on a substrate by applying to the substrate with a roller applicator a coating composition which contains beads of defined size.
