摘要： The present invention is an article useful in the field of wafer processing, for example. The article includes a substrate, a leveling layer, a joining layer, a photothermal conversion layer and a temporary carrier. The substrate has a first major surface, a second major surface and at least one three dimensional topographical feature extending from the first major surface and having an initial step height. The leveling layer is positioned adjacent to the first major surface and reduces a topography of the substrate to between about 5% and about 95% of the initial step height. The joining layer is positioned adjacent to the leveling layer and further reduces the topography of the substrate to less than about 20% of the initial step height. The photothermal conversion layer is positioned adjacent to the joining layer and the temporary carrier is positioned adjacent the photothermal conversion layer.

摘要： The present invention involves the use of powder coating methods to form coated abrasives. In one embodiment, the powder is in the form of a multiplicity of binder precursor particles comprising a radiation curable component. In other embodiments, the powder comprises at least one metal salt of a fatty acid and optionally an organic component that may be a thermoplastic macromolecule, a radiation curable component, and/or a thermally curable macromolecule. In either embodiment, the powder exists as a solid under the desired dry coating conditions, but is easily melted at relatively low temperatures and then solidified also at reasonably low processing temperatures. The principles of the present invention can be applied to form make coats, size coats, and/or supersize coats, as desired.

摘要： Abrasive products comprising abrasive grains bonded together or bonded to a backing by means of a binder compressing an oligomeric aminoplast resin having on average at least one pendant .alpha.,.beta.-unsaturated carbonyl group per oligomeric unit. The oligomeric aminoplast resins polymerize via free radical polymerization at the site of the .alpha.,.beta.-unsaturation. Polymerization is initiated by a source of free radicals. The source of free radicals can be generated by electron beam radiation or by an appropriate curing agent or initiator upon exposure to heat or radiation energy. The coated abrasive of this invention demonstrates improved grinding performance under severe conditions as compared with coated abrasives comprising radiation curable resins heretofore known.

摘要： An abrasive product comprising abrasive grains bonded together or bonded to at least one major surface of a backing sheet, by a binder formed from a precursor comprising an aminoplast resin having on average at least 1.1 pendant .alpha.,.beta.-unsaturated carbonyl groups per molecule. The binder is formed by curing the precursor at the .alpha.,.beta.-unsaturated site of the carbonyl group, by radiation energy or by heat, in the presence of an appropriate initiator system. The aminoplast resin can also contain pendant amino or hydroxy functional groups, which allow polymerization with condensation curable resins, such as phenolic, melamine, urea, urethane, and furfural resins. Polymerization at the unsaturated site of .alpha.,.beta.-unsaturated carbonyl group can be effected either by radiation energy or by heat, and curing at the sites of the amino or hydroxy functional group can be subsequently effected by heat. The binder of this invention can be used to form the make coat, size coat, both coats, or as a backing treatment of a coated abrasive. The binder material can also be used in fibrous non-woven abrasive products. The binder can be used in embodiments where only a single binder coat is employed.
