Abstract:
(EN) [Problem] The purpose of the present invention is to provide a hydrophilic resin composition having excellent UV curing properties and UV shielding performance, a hydrogel comprising the composition, and a molded article thereof. [Solution] A photocurable composition containing: (A) a monomer having one (meth)acryloyl structure; (B) a crosslinking agent having at least two acryloyl structures, and included in an amount of 0.1–10 wt% relative to the total of component (A) and component (B); (C) an inorganic UV shielding agent with 1–50 nm as the 50% cumulative particle size in a volume-weighted particle size distribution obtained by dynamic light scattering, and included in an amount of 0.5–10 parts by weight per a total 100 parts by weight of component (A) and component (B); and (D) a photoinitiator included in an amount of 0.05 to 1 part by weight per a total 100 parts by weight of component (A) and component (B), wherein all or a portion of component (A) is a hydrophilic monomer, and the content of the hydrophilic monomer is at least 70 wt% relative to the total weight of component (A) and component (B).
(FR) Le problème à résoudre par la présente invention est de fournir une composition de résine hydrophile ayant d'excellentes propriétés de durcissement aux UV et une excellente performance de protection contre les UV, un hydrogel comprenant la composition, et un article moulé associé. La solution selon l'invention porte sur une composition photodurcissable contenant : (A) un monomère ayant une structure (méth)acryloyle; (B) un agent de réticulation ayant au moins deux structures (méth)acryloyle, et inclus dans une quantité de 0,1 à 10 % en poids par rapport au total du composant (A) et du composant (B); (C) un agent de protection contre les UV inorganiques ayant de 1 à 50 nm en tant que taille de particule cumulée à 50 % dans une distribution de taille de particule pondérée en volume obtenue par diffusion dynamique de lumière, et inclus dans une quantité de 0,5 à 10 parties en poids pour 100 parties en poids du composant (A) et du composant (B); et (D) un photo-initiateur inclus dans une quantité de 0,05 à 1 partie en poids pour 100 parties en poids du composant (A) et du composant (B), la totalité ou une partie du composant (A) étant un monomère hydrophile, et la teneur du monomère hydrophile étant d'au moins 70 % en poids par rapport au poids total du composant (A) et du composant (B).
(JA) 【課題】 本発明は、優れた紫外線硬化特性および紫外線遮蔽能を有する親水性樹脂組成物、及び該組成物からなるヒドロゲルとその成形品を提供することを目的とする。 【解決手段】 (A)(メタ)アクリロイル構造を1つ有するモノマー、 (B)(メタ)アクリロイル構造を2つ以上有する架橋剤:(A)成分と(B)成分との合計に対して0.1~10重量%、 (C)動的光散乱法による体積基準の粒度分布における50%累積粒子径1~50nmを有する無機紫外線遮蔽剤:(A)成分と(B)成分との合計100重量部に対して0.5~10重量部、及び (D)光重合開始剤:(A)成分と(B)成分との合計100重量部に対して0.05~1重量部 を含み、前記(A)成分の一部又は全部が親水性モノマーであり、該親水性モノマーの含有量が前記(A)成分と前記(B)成分との合計重量に対して70重量%以上である、光硬化型組成物。
