Abstract
Description
technical field
[0001] This invention relates to imaging materials. In a preferred form it involves pearlescent photographic reflective paper. Background technique
[0002] Prior art reflective imaging output materials such as silver halide reflective images or inkjet reflective images typically comprise an imaging layer applied to a white reflective substrate. The white reflective substrate reflects ambient light back into the observer's eyes to form an image in the brain. Prior art substrates typically employ white reflective pigments such as TiO in a polymer matrix 2 or barium sulfate to form a white reflective substrate. Prior art reflective photographic papers also contain white pigments in the carrier just below the silver halide imaging layer to achieve image whiteness and sharpness when the image is exposed, because the white pigments reduce the amount of exposure energy scattered by the cellulose paper core . Details regarding the use of white pigments in highl...
