ABSTRACT:
An abrasive sheet is formed by uniformly painting slurry made of mixture of abrasive particles and adhesives on a surface of a base sheet with a pattern of irregularities by embossing. The slurry layer formed on the sheet hardens by drying at adequate temperature to form an abrasive layer. The abrasive layer has high and low abrasive parts formed by the surface tension of slurry, corresponding to the irregularities of the base sheet. The abrasive sheet is characterized by good planar precision of the abrasive layer, hardness to be peeled off the base sheet, and relatively easy producing method in which grooves are formed by the surface tension.
