  • Patent number: 8277937
    Abstract: Emulsion paint composition for obtaining special textile or suede effect comprising a filler at least partly consisting of pre-pigmented spherical aliphatic polyurethane particles particles. About 3-10% of the spherical particles has a particle size between 63-90 micrometers and 25-40% of the spherical particles has a particle size between 40-63 micrometers. Before applying the paint as a semi-opaque top coat the substrate is first coated with an opaque acrylic primer of a corresponding color and subsequently dried. The top coat is applied by brush in cross way fashion to obtain a suede effect, or it can be applied by roller, while subsequently a tool is used comprising a flat side provided with stiff parallel projecting fibers such as synthetic grass fibers, which are dragged over the fresh paint layer to obtain a linen effect.
