Abstract

A process is provided for fabricating a multilayer article possessing a protective layer which comprises: a) applying a curable protective layer-forming composition to the release coating side of a release liner; b) curing the curable protective layer-forming composition on the release liner; c) forming a plurality of release elements from the structure resulting from step (b), each release element possessing a cured protective layer releasably adhered on one side thereof to the release coating side of the release liner, the other side of the cured protective layer being exposed; d) applying the exposed side of the cured protective layer of a release element to a substrate layer with a quantity of curable adhesive disposed therebetween to provide a curable multilayer article; e) curing the curable multilayer article to adhesively bond the protective layer of its release element to its substrate layer; and, f) separating the cured multilayer article from its release liner to provide a multilayer article possessing a protective layer bonded to a substrate layer. The foregoing process is especially adapted for the manufacture of a high capacity optical information storage medium, in particular, a Blu-ray Disc.

Claims (10)

1 - 14 . (canceled)

15 . A structure comprising:

a) a layer of curable hardcoat-forming composition; and,

b) a release liner having a release layer on at least one side of a liner, the layer of curable hardcoat-forming composition, following the curing thereof, being releasably adhered to the release layer side of the release liner.

16 . The structure of claim 15 wherein the release layer of the release liner is obtained by applying a curable release-forming composition to a side of the liner and thereafter subjecting the release layer-forming composition to curing conditions.

17 . The structure of claim 16 wherein the release layer-forming composition is thermally curable and/or UV-curable.

18 . The structure of claim 15 wherein the layer of curable hardcoat-forming composition is thermally curable and/or UV-curable.

19 . The structure of claim 15 wherein the layer of curable hardcoat-forming composition is UV-curable and the release liner is transparent to UV light.

20 . The structure of claim 15 wherein the layer of curable hardcoat-forming composition exhibits following the curing thereof, scratch and abrasion resistance and/or antifingerprint properties.

21 - 25 . (canceled)
