Abstract
(EN)
[Problem] To provide a photocurable composition which exhibits excellent storage stability and which can form a cured film having good adhesion to an inorganic substrate. [Solution] This photocurable composition contains a silane coupling agent (A), a phosphoric acid (meth)acrylate monomer (B), a (meth)acrylate monomer (C) other than the components (A) and (B), a photopolymerization initiator (D) and a solvent (E). Because the solvent (E) contains an alcohol, by irradiating the photocurable composition with light, it is possible to form a cured film having good adhesion to an inorganic substrate and high hardness, and favorable storage stability is obtained so that gelling over time is suppressed.

Le problème décrit par la présente invention est de fournir une composition photodurcissable qui présente une excellente stabilité au stockage et qui peut former un film durci ayant une bonne adhérence à un substrat inorganique. La solution selon l'invention porte sur une composition photodurcissable qui contient un agent de couplage au silane (A), un monomère (méth)acrylate d'acide phosphorique (B), un monomère (méth)acrylate (C) autre que les composants (A) et (B), un initiateur de photopolymérisation (D) et un solvant (E). Du fait que le solvant (E) contient un alcool, en irradiant la composition photodurcissable avec de la lumière, il est possible de former un film durci ayant une bonne adhérence à un substrat inorganique et une dureté élevée, et on obtient une stabilité de stockage favorable de sorte que la gélification apparaissant au fil du temps est supprimée.
