Abstract

L'invention concerne la technologie utilisée pour créer des images bidimensionnelles ou tridimensionnelles dans un matériau polymère à l'aide d'un rayonnement électromagnétique pénétrant, et peut être utilisée pour marquer ainsi que pour produire des articles décoratifs et de souvenirs. Afin de créer une image à l'intérieur d'un article en matériau polymère, ou dans une partie de celui-ci, on expose ledit matériau à l'action d'un rayonnement électromagnétique focalisé pénétrant et on forme une image à partir des régions dans lesquelles l'absorption du rayonnement électromagnétique diffère de celle du matériau environnant. Ainsi, le rayonnement, dont l'intensité est inférieure à la valeur de seuil qui provoquerait une ionisation locale dans le matériau, déclenche des réactions chimiques au niveau des points de focalisation, lesquels convertissent les matériaux polymères en une composition différente de celle du matériau de départ. Spécifiquement, on utilise comme rayonnement pénétrant un faisceau laser, et on utilise des polymères à carbonisation en tant que matériau polymère. Ces moyens permettent de produire des images à la fois noires et en demi-teinte dans l'article.
