A method for preparing an article covered with a light absorption pattern film having a spectral distribution of a transmitted light corresponding to a pattern of a photomask, which comprises applying a liquid material for a light absorption film which contains a raw material for a silicon oxide, a raw material for a titanium oxide containing titanium oxide fine particles and a raw material for fine gold particles to the surface of a substrate, arranging the photomask over the applied coating film, irradiating an ultraviolet light to the coating film and then heating the film. The method can be used for preparing various articles covered with light absorption pattern films which have a variety of spectral distributions of a transmitted light, while maintaining the reflectance of visible lights at a low level.
L'invention concerne un procédé permettant de préparer un article recouvert d'un film d'absorption de lumière à motif qui présente une distribution spectrale de lumière transmise correspondant au motif d'un photomasque. Ledit procédé consiste à appliquer, sur la surface d'un substrat, un matériau liquide de film d'absorption de lumière contenant un matériau brut d'oxyde de silicium, un matériau brut d'oxyde de titane contenant des particules fines d'oxyde de titane, et un matériau brut de fines particules d'or; à placer le photomasque sur le film de revêtement appliqué; à irradier le film de revêtement à l'aide d'une lumière ultraviolette; et à chauffer ledit film. On peut utiliser ce procédé pour préparer des articles variés recouverts de films d'absorption de lumière à motif possédant une variété de distribution spectrale de lumière transmise, tout en conservant la réflectance de lumières visibles à un faible niveau.
