Abstract: Provided is a durable abrasive article which can conform even to a surface of a complicated shape and has an excellent abrasive power and which does not give any deep flaw to become a problem at a subsequent step and is not broken even when used in sanding the surface of the complicated shape. The abrasive article comprises a flexible resin film, an abrasive grain layer formed on the surface of the resin film, and an extremely flexible resin layer formed on the abrasive grain layer, wherein the flexible resin film has a thickness of 10 to 200 ?m, a tensile strength of 30 to 130 MPa and an elongation of 3 to 250%, wherein the abrasive grains of the abrasive grain layer are of P280 to P12, and wherein the extremely flexible resin layer has a 100% M of 1 to 20 MPa, a tensile strength of 20 to 90 MPa and an elongation of 250 to 1000%.

Abstract: An abrasive sheet has an abrasive particle layer formed on a surface of a thin flexible resin film. The abrasive sheet is produced by the steps of preparing a releasable film, forming a thin flexible resin film layer on a release agent applied surface of the releasable film and forming an abrasive particle layer on an upper surface of the resin film layer. Thereafter, the resin film having the abrasive particle layer formed thereon is removed from the releasable film, and the resin film having the abrasive particle layer formed thereon is cut into any suitable size. The abrasive sheet can provide higher polishing power during the polishing operation, but it polishes a surface while tracing or following any orange peel on the surface. Therefore, the abrasive sheet is effective for use as the polishing tool that can replace the fine compound buffing process currently utilized in the automobile repairing industry.
