Abstract
Abrasive articles and associated methods are shown that include one or more camouflaging layers that can be applied to a portion of the abrasive article. The one or more camouflaging layers can be applied over the size coat layer as a discontinuous colored layer covering a portion of the size coat layer. In an example, the camouflaging layer can be applied as a repeating pattern of one or more colors on the abrasive article. In an example, the camouflaging layer can be applied randomly to the abrasive article. The discontinuous layer can have a color markedly different than a color of the size coat layer and can be used to mask or minimize an appearance of particle imperfections or voids on the abrasive article. The discontinuous layer can be applicable to coated and non-woven abrasive articles in the form of sheets, discs, belts, pads, or rolls.
