Title
(EN) MULTILAYER HARD COATING FILM
(FR) FILM DE REVÊTEMENT DUR MULTICOUCHE
(JA) ハードコート積層フィルム
Abstract
(EN)
One embodiment of the present invention is a multilayer hard coating film which sequentially comprises, from the superficial layer side, a first hard coating and a resin film, and wherein: the first hard coating is formed from a coating material that contains a specific amount of (A) a polyfunctional (meth)acrylate and a specific amount of (B) a water repellent agent, while containing no inorganic particles; and the resin film comprises at least one layer of (α) an acrylic resin that contains 50-95% by mole of a structural unit derived from methyl methacrylate and 50-5% by mole of a structural unit derived from vinyl cyclohexane when the total of the structural units derived from polymerizable monomers is taken as 100% by mole. Another embodiment of the present invention is a multilayer hard coating film which comprises a second hard coating in addition to a first hard coating, and wherein: the first hard coating contains (C) a silane coupling agent in addition to the above-described components (A) and (B); and the second hard coating is formed from a coating material that contains a specific amount of (A) a polyfunctional (meth)acrylate and a specific amount of (D) inorganic fine particles having an average particle diameter of 1-300 nm.

Un mode de réalisation de la présente invention est un film de revêtement dur multicouche qui comprend séquentiellement, à partir du côté de la couche superficielle, un premier revêtement dur et un film de résine, et dans lequel : le premier revêtement dur est formé à partir d'un matériau de revêtement qui contient une quantité spécifique de (A), un (méth)acrylate polyfonctionnel et une quantité spécifique de (B), un agent hydrofuge, tout en ne contenant pas de particules inorganiques ; et le film de résine comprend au moins une couche de (α), une résine acrylique qui contient de 50 à 95 % molaires d'une unité structurale dérivée du méthacrylate de méthyle et de 50 à 5 % molaires d'une unité structurale dérivée du cyclohexane de vinyle lorsque le total des unités structurales dérivées de monomères polymérisables est considéré comme étant 100 % molaires. Un autre mode de réalisation de la présente invention est un film de revêtement dur multicouche qui comprend un deuxième revêtement dur en supplément d'un premier revêtement dur, et dans lequel : le premier revêtement dur contient (C), un agent de couplage au silane en plus des composants décrits ci-dessus (A) et (B) ; et le deuxième revêtement dur est formé à partir d'un matériau de revêtement qui contient une quantité spécifique de (A), un (méth)acrylate polyfonctionnel et une quantité spécifique de (D), des particules fines inorganiques ayant un diamètre de particule moyen de 1 à 300 nm.
