Title
(EN) LASER MARKABLE COMPOSITIONS
(FR) COMPOSITIONS MARQUABLES AU LASER
Abstract
(EN)
An aqueous radiation curable laser markable composition comprising a polymerizable compound, a photoinitiator, a colourforming agent and an optional optothermal converting agent, characterized in that the photoinitiator has a Molecular Weight of at least 250.
(FR)
L'invention concerne une composition pouvant être marquée au laser durcissable par rayonnement aqueux comprenant un composé polymérisable, un photo-initiateur, un agent colorant et un agent éventuel de conversion optothermique. L'invention est caractérisée en ce que le photo-initiateur a un poids moléculaire d'au moins 250.
