  • Patent number: 10184070
    Abstract: A thermosettable pressure sensitive adhesive tape comprising at least first and second adhesive layers bonded together. Each of the adhesive layers comprises a thermosettable pressure sensitive 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 pressure sensitive 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.
