Abstract:
A method of manufacturing a protective coating on a color filter, said color filter comprising a transparent substrate, a colored layer having an upper and lower surface, said lower surface of said colored layer overlying said transparent substrate; which comprises the steps of:a. adhering an adhesive article to said color filter, wherein said adhesive article comprises (i) a radiation curable adhesive layer having an upper surface and a lower surface, said adhesive layer comprising an acrylic pressure sensitive adhesive; (ii) a transparent carrier layer, having an upper surface and a lower surface, wherein the lower surface of said transparent carrier layer overlies and is adhered to the upper surface of said adhesive layer; so that the lower surface of said adhesive layer is adhered to said upper surface of said colored layer;b. positioning a photomask over said adhesive article; c. exposing said adhesive article to radiation through said photomask to cure portions of said adhesive layer and leaving portions of said adhesive layer uncured; d. removing said carrier layer with said uncured portions of said adhesive layer adhered thereto to form a multilayer structure comprising a transparent substrate, a colored layer and a protective coating overlying said colored layer, wherein said protective coating comprises the radiation cured portions of the adhesive layer; and e. baking said multilayer structure to fully cure said protective coating.
