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.
