<P>PROBLEM TO BE SOLVED: To provide a panel that has mitigated the problem of accumulation of heat generated as a panel body absorbs light, in the panel having the panel body having light-absorbing/heat-storing properties. <P>SOLUTION: The panel 51A has a panel body 52A that is made of a translucent thermoplastic resin which has light-absorbing/heat-storing properties, that is, the properties of absorbing light, converting the light into heat, and storing the heat internally. The panel body 52A includes a translucent first layer 2a and a translucent second layer 2b that is laminated with the first layer 2a and exhibits more pronounced light-absorbing/heat-storing properties than the first layer 2a. The light-absorbing/heat-storing panel body 52A has a multilayer structure comprising at least two layers, that is, the layer 2b for IR absorption and the layer 2b serving as a heat-insulating layer. The heat-insulating layer 2a blocks the radiation of heat generated by IR absorption by the IR-absorbing layer 2b, thereby enabling prevention of a temperature increase caused by the heat radiated from the panel body 52A. <P>COPYRIGHT: (C)2013,JPO&INPIT |
