Abrasive sheet and method for producing same

摘要

An abrasive sheet for precisely abrading a workpiece surface includes an adhesive and an abrading layer made by drying a slurry which is a mixture of abrasive particles and a binder. The abrading layer is preferably of thickness less than about 1.5 times the average size of the abrading particles and has one surface attached to a plastic base sheet through a layer of the adhesive. At least some of the abrading particles in the abrading layer have their end parts at the other surface of the abrading layer which, together with these end parts of the abrading particles, forms a smooth flat abrading surface without irregularly distributed protrusions and indentations.
