Title
(EN) ABSORBER FOR RAYS OF LIGHT OUT OF VISIBLE REGION
(FR) ABSORBEUR DE RAYONS LUMINEUX HORS DU SPECTRE VISIBLE
Abstract
(EN)
An absorber for the rays of light out of a visible region, which comprises a transparent resin base containing conductive zinc antimonate anhydride and at least one of the following three infrared ray absorbents a-c, wherein transmissivity is high in a visible region and low in both ultraviolet region and infrared regions: a) metal ions comprising bivalent copper ions; b) particulate metal oxide comprising indium oxide or tin oxide or both of them; c) phthalocyanine compound. Such an absorber may alternatively comprise a transparent base on which is provided either an absorptive layer for rays of light out of a visible region which contains conductive zinc antimonate anhydride and at least one kind of substance selected from the above a-c in the synthetic resin of the base or an absorptive layer for rays of light out of a visible region which comprises an accumulated body of particulate metal oxide formed of anhydrous zinc antimonate anhydride and indium oxide, tin oxide or both thereof.
(FR)
Cette invention concerne un absorbeur de rayons lumineux se trouvant hors du spectre visible, lequel absorbeur comprend une base de résine transparente qui possède une transmissivité élevée dans le spectre visible, et une faible transmissivité tant dans le domaine des infrarouges que celui des ultraviolets. Cette base de résine transparente contient un anhydride d'antimoniate de zinc conducteur et l'un au moins des trois absorbeurs (a-c) de rayonnement infrarouge suivants: (a) des ions métalliques comprenant des ions cuivre bivalents; (b) un oxyde métallique particulaire comprenant de l'oxyde d'indium ou de l'oxyde d'étain, ou encore, les deux; et (c) un composé phtalocyanine. Dans un autre mode de réalisation, cet absorbeur peut comprendre une base transparente sur laquelle est déposée l'une des deux couches suivantes: soit une couche absorbant les rayons lumineux se trouvant hors du spectre visible, laquelle couche contient de l'anhydride d'antimoniate de zinc conducteur ainsi que l'une au moins des substances choisies dans le groupe a à c et contenues dans la résine synthétique de la base; soit une couche absorbant les rayons lumineux se trouvant hors du spectre visible, laquelle couche contient un corps issu de l'accumulation, d'une part, d'un oxyde métallique particulaire se composant d'anhydride d'antimoniate de zinc anhydre et, d'autre part, d'oxyde d'indium ou d'oxyde d'étain, ou encore des deux.
