Abstract
(EN)
[Problem] To provide a photocurable black composition for forming a black shielding material that reduces the reflection of light irradiating a display from the user side. [Solution] A photocurable black composition comprising: (A) an alkali-soluble resin; (B) a photopolymerization initiator; (C) a photopolymerizable polyfunctional monomer; and (D) carbon black having a nitrogen adsorption specific surface area of 300 m2/g or more based on JIS K6217-2:2017.. When irradiated with light through a transparent base material, a cured film of a black coated base material obtained from the photocurable black composition suppresses the reflection of the light so as to suppress the occurrence of a white blur on the cured film.

[Problème] Fournir une composition de noir photodurcissable pour former un matériau de protection noir qui réduit la réflexion de la lumière irradiant un affichage depuis le côté utilisateur. [Solution] La présente invention concerne une composition de noir photodurcissable comprenant : (A) une résine soluble dans les alcalis ; (B) un amorceur de photopolymérisation ; (C) un monomère polyfonctionnel photopolymérisable ; et (D) du noir de carbone ayant une surface spécifique d’adsorption d’azote de 300 m2/g ou plus sur la base de JIS K6217-2:2017. Lorsqu’il est irradié avec de la lumière à travers un matériau de base transparent, un film durci d’un matériau de base revêtu de noir obtenu à partir de la composition de noir photodurcissable supprime la réflexion de la lumière de façon à supprimer l’apparition d’un trouble blanc sur le film durci.
