摘要：A method of preparing a coated abrasive article in which the presence ofmultiple layers of abrasive grains are minimized. In one variation, the method comprisesthe steps of: (a) providing a backing; (b) applying a make coat precursor to the backing;(c) partially curing the make coat precursor; (d) applying, preferably by projecting, aplurality of abrasive grains into the partially cured make coat precursor; and (e)completely curing the partially cured make coat precursor. In another variation of thismethod, a size coat precursor is applied over the abrasive grains and cured make coat,and the size coat precursor is completely cured. In another variation of this method, asize coat precursor is applied over the abrasive grains and the partially cured make coatprecursor, and the make coat precursor and the size coat precursor are completelycured. The make coat precursor preferably comprises an unsaturated resin thatpolymerizes via a free radical polymerization mechanism at the site of α,β-unsaturation.
