    摘要: When obtaining microcapsules by covering a hydrophobic material with an aminoaldehyde polycondensation product as a wall-forming material in an acidic aqueous medium containing an anionic water-soluble polymer, a microcapsule slurry having a high solid content and low viscosity can be obtained by using as the anionic water-soluble polymer a multi-component copolymer consisting as essential monomer components thereof of at least three types of acrylic monomers selected respectively from (A) acrylic acid and/or methacrylic acid, (B) acrylonitrile and/or methacrylonitrile and (C) an acrylamidoalkylsulfonic acid and/or sulfoalkyl acrylate. Over a wide pH range, the microcapsule slurry obtained in accordance with this invention undergoes little viscosity changes and exhibits neither destruction of its dispersed state nor coagulating tendency. Resulting microcapsules have a sharp particle size distribution and are equipped with dense wall films.

    摘要: The super finishing stone has such a shape that a width of an abrasive surface in a direction perpendicular to a radial direction becomes gradually narrower from outside to inside in the radial direction, when the raceway surface and the abrasive surface in contact with the raceway surface are seen at a plurality of sections perpendicular to the radial direction of the object to be worked, so that the abrasive surface and the raceway surface in contact with the raceway surface may intersect with each other at a constant angle at opposite side edges of the abrasive surface.
