A thermosettable adhesive taped article comprising at least first and second adhesive layers bonded together. Each of the adhesive layers comprises a thermosettable adhesive, which is the photo-polymerization reaction product of starting materials. The starting materials for each adhesive layer comprises at least a photo-polymerizable acrylic component and a thermosettable epoxy component. The thermosettable adhesive, used for either of the two adhesive layers, is not black when fully cured without the presence of a black coloring pigment. The first adhesive layer is made from a layer of starting materials that is thin enough to allow substantial photo-polymerization of the starting materials, even with the starting materials containing a sufficient amount of a black coloring pigment to cause the first adhesive to have a black color after the first adhesive is substantially cured. The second adhesive layer is made from a layer of starting materials which has a thickness that would be sufficiently thick to prevent substantial photo-polymerization (e.g., with UV light) of the starting materials, if the starting materials contained enough of a black coloring pigment to cause the second adhesive to have a black color after the second adhesive is cured.
An article comprising a thermosettable pressure sensitive adhesive tape and at least one of an opaque substrate and a transparent substrate, with said tape comprising:
