The method of the invention simplifies the production process of a coated abrasive article and shortens the production time by omitting the step of sealing a porous substrate and by shortening the curing time of a bonding agent. A process for producing a coated abrasive article comprising the steps of: providing a porous substrate; applying a first bonding agent on at least one surface of the porous substrate to form a make coat layer; placing abrasive particles on the make coat layer; and applying a second bonding agent on the make coat layer and the abrasive particles to make a size coat layer, wherein, said first bonding agent, second bonding agent or both agents comprise (i) a solid epoxy resin having a melt viscosity coefficient of 1,000 cps (1 Pa. s) or more at 120 DEG C and (ii) a curing catalyst. |
