Abstract: front page image
(EN) Light-diffusing particles (10) that comprise a core (10c) and a shell (10s). The core (10c) is formed from a first binder (11) and first fine particles (12). The first fine particles (12) include a low-refractive-index fine particle (12a) that has a lower refractive index than the first binder (11). The first fine particles (12) contact and are covered by the first binder. The shell (10s) contacts an outer surface of the core (10c) and covers the core (10c). The shell (10s) includes spherical particles (13) that have a particle diameter of 50–450 nm and give the shell (10s) surface roughness (A).
(FR) La présente invention concerne des particules de diffusion de lumière (10) qui comprennent un cœur (10c) et une enveloppe (10s). Le cœur (10c) est formé à partir d'un premier liant (11) et de premières particules fines (12). Les premières particules fines (12) comprennent une particule fine à faible indice de réfraction (12a) qui a un indice de réfraction inférieur à celui du premier liant (11). Les premières particules fines (12) entrent en contact et sont recouvertes par le premier liant. L'enveloppe (10s) entre en contact avec une surface extérieure du cœur (10c) et recouvre le cœur (10c). Le cœur (10s) comprend des particules sphériques (13) qui ont un diamètre de particule de 50 à 450 nm et donnent la rugosité (A) de surface de l'enveloppe (10s).
(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、第一微粒子(12)とによって形成されている。第一微粒子(12)は、第一バインダー(11)の屈折率よりも低い屈折率を有する低屈折率微粒子(12a)を含む。第一微粒子(12)は、第一バインダーに接触して覆われている。シェル(10s)は、コア(10c)の外面に接触してコア(10c)を覆う。シェル(10s)は、50nm~450nmの粒子径を有しシェル(10s)に表面凹凸(A)を付与する球状粒子(13)を含む。
