Abstract:
An article comprising (a) a foam core layer having first and second major surfaces, and (b) a thermosettable sealant layer of a photo-polymerizable composition having,i) at least one photo-polymerizable epoxy-containing monomer, andii) a two-component initiator comprising(1) at least one salt of an organo-iron complex cation, and(2) at least one accelerator represented by the formula ##STR2##wherein each R.sup.1, independently, can be hydrogen or a radical moiety selected from substituted and unsubstituted alkyl, alkenyl, alkyniyl, and alkoxy groups containing from 1 to 30 carbon atoms, or groups of one to four substituted or unsubstituted aromatic rings wherein two to four rings can be fused or unfused, or two R.sup.1 s taken together can form at least one ring which is saturated or unsaturated and the ring can be substituted or unsubstituted and wherein when the molecule contains more than two aromatic hydroxy groups, at least two of the hydroxy groups must be adjacent to each other, said sealant layer applied onto the first major surface of said core layer, said sealant layer having a surface available for contacting a substrate.
