Abstract
An optical disc is described that bears, on one surface, a plurality of color-forming layers that can form a multicolored image when heated in contact with a thermal print head. The color-forming composition comprises color-forming layers and thermally-insulating spacers and is designed such that warping of the optical disc in conditions of changing temperature and humidity is minimized. The compliance of the color-forming composition is such that intimate contact between the thermal print head and the printable surface of the disc can be maintained as one is translated relative to the other. Methods for assembling such an optical disc are provided.
