LIGHT ACCUMULATION TYPE THERMAL COLOR-CHANGEABLE LAMINATE

摘要

PURPOSE:To provide the title laminate effectively developing both of the afterglow effect due to light accumulation type pigment and the discoloration effect due to a thermally color-changeable material and effectively adjusting the afterglow brightness of the light accumulation type pigment. CONSTITUTION:A light accumulation type thermally color-changeable laminate 1 is constituted by laminating a thermal discoloration layer 3 generating a color change by a temp. change to change reflectivity to the rear surface of a light accumulation type pigment layer 2.
