Abstract
Provided are an abrasive tape suitable for finishing of surfaces or the like of precision components such as optical connector ferrules and semiconductor wafers, and a process for producing it. A coating agent in which abrasive particles having an average particle size in the range of 1 to 200 mμ are dispersed in a binder resin solution. The coating agent is applied, with intervention of a primer layer if necessary, onto a base for abrasive tape to form an abrasive layer, thus obtaining an abrasive tape.
