Abstract

L'invention a trait à des disques optiques et à des procédés de fabrication de ces derniers. Dans un mode de réalisation, le disque optique comprend : au moins deux substrats de plastique (1) entre lesquels sont disposées une couche de liage et une couche de données, au moins l'un des substrats (1) étant un substrat de côté lecture comprenant au moins 0,01 % en poids de colorant, sur la base du poids total du substrat de côté lecture, et le substrat de côté lecture présentant un indice de liaison UV supérieur ou égal à 0,5 environ. L'invention concerne également un procédé de fabrication du disque optique consistant : à former un premier substrat de plastique comprenant au moins 0,01 % en poids de colorant, sur la base du poids total du premier substrat de plastique, l'indice de liaison UV du premier substrat de plastique étant adapté pour être supérieur ou égal à 0,5 environ ; à disposer une couche de données entre le premier substrat de plastique et un second substrat ; à lier le premier substrat de plastique au second substrat de plastique au moyen d'une couche de liage ; et à polymériser la couche de liage.
