BLACK METAL THERMAL IMAGE FORMING TRANSPARENT COMPONENT

摘要

PROBLEM TO BE SOLVED: To provide a thermally imageable material for a white and black transparent imageable, especially, a thermally imageable component covering a black metal. SOLUTION: A component containing a base material at least partially covered with a layer containing a black aluminum layer containing an oxygen atom in an amt. of at least 19-58% with respect to the total number of aluminum and oxygen atoms and having transmission optical density of at least 0.3 within a wavelength range of 200-1100 nm is provided (a). The component is imagewise irradiated with radiation with a wavelength of 220-1100 nm (b). Irradiated radiation substantially increases the light transmissivity of the component in the region irradiated with radiation and a gas generating polymer containing 5 wt.% or more of heat effective gas is not contained in the component (c).
