There is provided an adhesive article including (a) a radiation curable adhesive layer comprising an acrylic pressure sensitive adhesive and, optionally, an acrylated urethane polymer; and (b) a transparent carrier layer. The adhesive article may contain a radiation curable epoxy layer between the radiation curable adhesive layer and the transparent carrier layer. This adhesive article is particularly useful in preparing protective coatings on color filters for use in a liquid-crystal display panel structure. The radiation curable epoxy layer and radiation curable pressure sensitive adhesive are applied to the color filter and then exposed to UV radiation. The UV radiation exposure transforms the pressure sensitive adhesive from a removable adhesive to a permanent adhesive. The color filter with the UV cured adhesive layer is then baked to fully cure the adhesive layer and to transform the adhesive further into a near structural adhesive. The cured adhesive layer, and cured epoxy layer, if present, make up the protective coating for the color filter. |
