摘要： An abrasive material which is especially excellent in the dispersion of abrasive grains even when the grains are contained in a large amount, and which has stable polishing properties and is effective in diminishing scratches. The abrasive material comprises a polishing part which can be obtained by introducing given amounts of butadiene, styrene, methyl methacrylate, itaconic acid, acrylic acid, α-methylstyrene dimer, and t-dodecyl mercaptan into an autoclave, reacting them at 75°C for 16 hours to obtain an emulsion of a copolymer, adjusting the pH of this emulsion to 8.5, adding thereto a cerium oxide powder having an average primary-particle diameter of 0.3 νm, stirring the resultant mixture to obtain an aqueous dispersion, thinly spreading this aqueous dispersion on a film, drying it, and then pressing the resultant dry mixture with a mold press. The polishing part may have a crosslinked structure. The abrasive material is suitable for use as, e.g., a polishing pad for polishing the surface of, e.g., a semiconductor wafer.

摘要： An object of the present invention is to provide a polishing body, wherein the abrasive in the polishing body are extremely dispersed well, which provides stable polishing performance in the polishing process, and which can effectively reduce the occurrence of scratches even in a case a large quantity of the abrasive are contained. A polishing part constituting the polishing body in the invention is produced obtained by loading predetermined amounts of butadiene, styrene, methyl methacrylate, itaconic acid, acrylic acid, α-methylstyrenedimer, and t-dodecylmercaptan in an autoclave, making the mixture react for 16 hours at 75°C to obtain an emulsion wherein a copolymer is dispersed, adjusting this emulsion to pH8.5, incorporating cerium oxide powder with an average primary particle diameter of 0.3µm and stirring to obtain an aqueous dispersion, drying this aqueous dispersion by spreading it thinly across a film, and mold pressing the dried product obtained. The above-mentioned polishing part may have a crosslinked structure. The polishing body in the invention can be used favorably in a polishing pad and the like, for polishing the surface of a semiconductor wafer or the like.

摘要： This invention relates to coated abrasive products having a pressure-sensitive adhesive layer coatable from water. Many coated abrasive products, especially coated abrasive sheets and discs, are mounted on a support pad, sometimes called a back-up pad, during use. One means for securing the coated abrasive article to the support pad calls for a pressure-sensitive adhesive. Typically, the surface of the coated abrasive article not containing the abrasive grains will bear a layer of pressure-sensitive adhesive. For many years, pressure-sensitive adhesives have been coated from organic solvent solutions onto the non-abrasive side of the coated abrasive article with excellent results. However, because recent governmental regulations require reductions in solvent emissions, the coated abrasive industry desires to eliminate all organic solvents from their coating operations. This invention provides a coated abrasive product having a backing bearing abrasive grains on one major surface thereof and a pressure-sensitive adhesive, coatable from water, on the other major surface thereof. The pressure-sensitive adhesive can be used to secure the coated abrasive to a support pad or back-up pad. The support pad provides the coated abrasive with the necessary foundation during abrading operations. The pressure-sensitive adhesives of this invention can adequately secure the coated abrasive to the support pad even at high rotation speeds and at high grinding pressures. Previously known pressure-sensitive adhesives for coated abrasives that are coatable from water were unable to provide this property.

摘要翻译：本发明涉及具有可从水涂覆的压敏粘合剂层的涂覆磨料制品。许多涂覆的磨料产品，特别是涂覆的磨料片和盘片，在使用过程中安装在支撑垫上，有时称为后备垫。将涂覆的磨料制品固定到支撑垫上的一种手段需要一种压敏粘合剂。通常，不含磨粒的涂覆磨料制品的表面将承载一层压敏粘合剂。多年来，压敏粘合剂已经从有机溶剂溶液涂覆到涂覆的磨料制品的非研磨侧，结果非常好。然而，由于最近的政府法规要求减少溶剂排放，因此涂层磨料行业希望从其涂层操作中消除所有有机溶剂。本发明提供了一种涂覆磨料产品，其具有在其一个主表面上带有磨料颗粒的背衬和在其另一主表面上可由水涂覆的压敏粘合剂。可以使用压敏粘合剂将涂覆的磨料固定到支撑垫或支撑垫上。支撑垫在研磨操作期间为涂覆的磨料提供必要的基础。本发明的压敏粘合剂即使在高旋转速度和高研磨压力下也能将涂覆的磨料充分地固定在支撑垫上。以前已知的可从水涂覆的涂覆磨料的压敏粘合剂不能提供该性能。

摘要： An abrasive multi-disc cutter is formed by uniformly coating a cylindrical holder with a mixture of diamond powder and resin. The holder is rotated about its longitudinal axis while one or more beams of laser energy are used to ablate the resin for forming a plurality of annular depressions in the coating, the depressions being equally spaced along the longitudinal axis of the cylindrical holder. An abrasive annular cutting disc is thereby provided between each pair of successive annular depressions. The cutter is used to cut a plurality of parallel, spaced ink cavities in a piezoelectric substrate forming part of an ink jet printer printhead.
