摘要： A fine feldspathic earthenware including a body and a glaze layer covering surfaces of the body. The body has water absorption percentage of not lower than 3% and lower than 15% and includes an annular bottom formed on a bottom portion of the body. The glaze layer is absent on a surface of the annular bottom, and the surface of the annular bottom is covered with an annular vitrified layer which has substantially no water absorbing property. The vitrified layer is formed by coating the surface of the annular bottom with a composition having lower refractoriness than the body, and biscuit-firing the composition together with the body.

摘要： In a magnetic recording medium comprising a non-magnetic substrate having opposed major surfaces, a non-magnetic undercoat on one major surface of the substrate, a magnetic layer on the undercoat, and a non-magnetic backcoat on the other major surface of the substrate, at least one of said undercoat and said backcoat is formed of a coating composition comprising a radiation curable base resin preferably having a radiation-sensitive double bond such as acrylic, maleic or allylic double bond, an optional thermoplastic resin, and an effective amount of an anti-static agent selected from known surface-active agents, the composition being cured through crosslinking by exposure to radiation. The magnetic recording medium is prepared by mixing the resins with the anti-static agent, coating the substrate with the composition, and exposing the coating to radiation.
