The problem addressed by the present invention is to provide an aqueous adhesive composition that is for print lamination and that is additionally provided with light resistance with respect to ultraviolet rays while maintaining adhesiveness of a plastic film and a substrate, and takes into consideration the environmental impact, safety, and industrial health considerations resulting from using the aqueous adhesive. The aqueous adhesive composition for print lamination is provided with light resistance with respect to ultraviolet rays and adhesiveness taking into consideration the environmental impact, safety, and industrial health consideration by means of containing: a binder resin composition having an aqueous acrylic resin and an epoxy compound as required components; and an ultraviolet-ray-absorbing agent of which the wavelength region of maximum absorption is a specific wavelength region. L'invention propose une composition adhésive aqueuse pour stratification de cliché, qui présente en outre une résistance à la lumière, notamment aux rayons ultraviolets, tout en conservant l'adhésivité d'un film en matière plastique et d'un substrat, et en prenant en compte l'incidence sur l'environnement, la sécurité et les questions de santé liées à son utilisation en milieu industriel. Cette composition adhésive aqueuse pour stratification de cliché présente des qualités d'adhésivité et de résistance à la lumière, notamment aux rayons ultraviolets, et prend en compte l'incidence sur l'environnement, la sécurité, et les questions de santé liées à son utilisation en milieu industriel. Elle contient: une composition de résine liante comportant une résine acrylique aqueuse et un composé époxyde comme constituants requis; et un agent d'absorption des rayons ultraviolets dont la zone de longueur d'onde d'absorption maximale est une zone de longueur d'onde spécifique.
