Abstract
(EN) Light-diffusing particles (10) that comprises a core (10c) and a shell (10s). The core (10c) includes a first binder (11) and a core fine particle (12). The first binder (11) contacts an outer surface of the core fine particle (12). The core fine particle (12) has a lower refractive index than the first binder (11), a circularity of at least 0.85, and a particle diameter of 0.1–4 μm. The core (10c) contacts an outer surface of the core (10c) and covers the core (10c).
(FR) La présente invention concerne des particules de diffusion de lumière (10) qui comprennent un noyau (10c) et une enveloppe (10s). Le noyau (10c) comprend un premier liant (11) et une particule fine de noyau (12). Le premier liant (11) entre en contact avec une surface externe de la particule fine de noyau (12). La particule fine de noyau (12) a un indice de réfraction inférieur à celui du premier liant (11), une circularité d’au moins 0,85 et un diamètre de particule de 0,1 à 4 µm. Le noyau (10c) entre en contact avec une surface externe du noyau (10c) et recouvre le noyau (10c).
(JA) 光拡散粒子(10)は、コア(10c)と、シェル(10s)とを備えている。コア(10c)は、第一バインダー(11)と、コア微粒子(12)とを含む。第一バインダー(11)がコア微粒子(12)の外面に接触している。コア微粒子(12)は、第一バインダー(11)の屈折率よりも低い屈折率、0.85以上の円形度、及び0.1μm~4μmの粒子径を有する。コア(10c)は、コア(10c)の外面に接触してコア(10c)を覆っている。
