Abstract

L'invention concerne des supports optiques comportant des repères non brouilleurs ou sensiblement non brouilleurs, avec possibilité de lecture des données à partir des supports optiques. Les supports optiques utilisent certaines formulations de revêtements chromogènes décrites dans le mémorandum descriptif. Des revêtements de protection employés pour améliorer les revêtements chromogènes sont également décrits, ainsi que des procédés d'incorporation desdits revêtements dans les supports optiques. Dans des modes de réalisation préférés, le repère est créé dans un revêtement photosensible appliqué sur les supports optiques, puis polymérisé à l'aide d'une première lumière. Une seconde lumière, qui présente une bande de longueurs d'onde sensiblement distincte de celle de la première lumière, est utilisée pour imprimer une image d'un repère dans le revêtement. Le revêtement est résistant à de nombreuses influences extérieures, telles que les conditions écologiques ambiantes ou l'usure physique.
