Abstract
A method for preparing a coated abrasive article wherein the a plurality of abrasive grains are applied to a make coat such that the abrasive grains are substantially a mono-layer. The make coat precursor is a pressure-sensitive adhesive-like or pressure-sensitive adhesive. The make coat precursor is partially cured to approximate a pressure-sensitive adhesive-like layer or when fully cured is a pressure-sensitive adhesive. The make coat precursor has sufficient 'tack' to hold the abrasive grains during the application and curing of the size coat, resulting in a substantially monolayer of abrasive grains.
