Abstract:
An abrasive sheet having improved properties which enable precise polishing and finishing is prepared by (1) coating an abrasive material-containing slurry on a concave face of an embossed first substrate and then UV-curing or pre-drying with heat the coating layer to form an abrasive material coating layer on the embossed first substrate; (2) coating an adhesive on one side of a second substrate to form an adhesive layer thereon; (3) combining the first and second substrates such that the abrasive material coating layer is bonded to the adhesive layer to form a laminate; and (4) separating the first substrate from the laminate formed in step (3), to obtain an abrasive sheet having an embossed abrasive material coating layer.
