  • Curable composition and article possessing protective layer obtained therefrom
    Patent number: 7622514
    Abstract: A curable composition contains: a) functionalized colloidal silica obtained from the reaction of surface hydroxyl groups of colloidal silica with at least one functionalizing silane of the general formula: (Rl)aSi(OR2)4?a wherein each R1 is, independently, a monovalent alkyl, cycloalkyl, aryl, alkaryl or aralkyl group of up to 18 carbon atoms, optionally possessing at least one chemically reactive functionality selected from the group consisting of alkenyl, acrylate and epoxy; b) at least one first curable monomer possessing at least one of alkenyl and acrylate functionality; c) at least one second curable monomer possessing epoxy functionality; d) at least one third curable monomer possessing at least one of alkenyl and acrylate functionality together with epoxy functionality, the third curable monomer replacing or supplementing the first and/or second curable monomer, provided, that when the third curable monomer replaces both the first and second curable monomers, the functionalized colloidal silica po

  • Process for manufacturing a multilayer article possessing a protective layer
    Publication number: 20080292861
    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 pos
