The disclosure is generally related to a coating composition, and more particularly to a decorative effect coating composition capable of producing a multicolored and/or multishaded appearance in a single application. The multicolor effect arises through multiple tinting colorants that are substantially immiscible and which separate into separate layers upon application. The color difference between the two layers should be at least about 0.25 delta E units. Additional decorative effects may be applied through shearing the surface with a putty knife or other instrument while the coating composition is still in the liquid or simi-liquid state.
L'invention concerne, de façon générale, une composition de revêtement et, plus particulièrement, une composition de revêtement à effet décoratif capable de produire une apparence multicolore et/ou multifoncé en une seule application. L'effet multicolore est obtenu par de multiples colorants de coloration qui sont sensiblement non miscibles et qui se séparent en couches distinctes lors de l'application. La différence de couleur entre les deux couches doit être d'au moins 0,25 unité E delta. Des effets décoratifs supplémentaires peuvent être appliqués par cisaillement de la surface au moyen d'un couteau à mastiquer ou autre instrument, alors que la composition de revêtement est encore à l'état liquide ou semi-liquide
