1. A thermally curable adhesive film comprising:
a crosslinked (meth)acrylate matrix; and
a thermally curable, one-part epoxy/thiol resin composition incorporated within the crosslinked (meth)acrylate matrix; wherein the thermally curable, one-part epoxy/thiol resin composition comprises:
an epoxy resin component comprising an epoxy resin having at least two epoxide groups per molecule;
a thiol component comprising a polythiol compound having at least two thiol groups;
a nitrogen-containing catalyst for the epoxy resin; and
an organic acid, the organic acid being soluble in the epoxy/thiol resin composition, wherein soluble in the epoxy/thiol resin composition means when the organic acid is incorporated in the epoxy/thiol resin in an amount of 5 wt-%, it produces an epoxy/thiol resin composition with at least 80% clarity and at least 80% transmission.
