A coated abrasive product having a backing bearing abrasive grains on one major surface thereof and a pressure-sensitive adhesive, coatable from water, on the other major surface thereof. The pressure-sensitive adhesive can be used to secure the coated abrasive to a support pad or back-up pad. The support pad provides the coated abrasive with the necessary foundation during abrading operations. The pressure-sensitive adhesives of this invention can adequately secure the coated abrasive to the support pad even at high rotation speeds and at high grinding pressures. Previously known pressure-sensitive adhesives for coated abrasives that are coatable from water were unable to provide this property.
