<P>PROBLEM TO BE SOLVED: To provide a light-resistant heat-fading body that significantly improves light resistant robustness of a heat-fading material which develops color or fades by an electron transfer reaction between an electron donating color developable organic compound and an electron accepting compound, by excluding oxygen gas. <P>SOLUTION: The light-resistant heat-fading body is constituted by covering the whole surface including the periphery of a heat-fading layer with an oxygen gas barrier layer, wherein the oxygen permeability of the oxygen gas barrier layer is 1,200 ml/(m<SP POS="POST">2</SP>×d×MPa) or less, preferably, is 0 to 600 ml/(m<SP POS="POST">2</SP>×d×MPa). <P>COPYRIGHT: (C)2012,JPO&INPIT |
