Abstract: A thermally conductive conformable interface pad for inter-position between a heat generating solid state electronic device and a heat sinking surface. The interface comprises a laminate of at least two layers, including a relatively soft conformable body layer with at least one surface consisting of an integrally bonded anti-blocking layer. The conformable body layer preferably comprises a thermally stable wax consisting of an alkyl substituted poly (hydro, methyl-siloxane) wax and a thermally conductive particulate solid, while the anti-blocking layer may comprise a mixture of an alkyl substituted poly (hydro, methyl-siloxane) wax and a silicone wax, a glassy polyester layer, or a cross-linked acrylic layer.

Abstract: An X-ray label includes a substrate that is transparent to X-ray radiation and X-ray absorbing pigment deposited on the substrate in images that provide identification data under visible light and that create corresponding images in an X-ray film emulsion layer when the film is exposed to X-ray radiation. Preferably, the X-ray absorbing pigment is deposited on the substrate using a thermal print process to quickly and consistently transfer X-ray absorbing pigment characters from the ribbon to the X-ray transparent substrate.
