A composition is disclosed, which comprises (I) an aryl component; (II) a methyl component; and (III) a hydrosilylation catalyst. The (I) aryl component comprises (A) an organopolysiloxane and (B) an organohydrogenpolysiloxane. Similarly, the (II) methyl component comprises (A) an organopolysiloxane and (B) an organohydrogenpolysiloxane. A method of preparing the composition is also disclosed. Further, a method of preparing an article, e.g. a light diffuser, and a lighting device comprising the light diffuser are disclosed. Finally, a method of diffusely transmitting light with the light diffuser is disclosed. La présente invention concerne une composition, comprenant un constituant aryle (I) ; un constituant méthyle (II) ; et un catalyseur d'hydrosilylation. Le constituant aryle (I) comprend un organopolysiloxane (A) et un organohydrogénopolysiloxane (B). De manière similaire, le constituant méthyle (II) comprend un organopolysiloxane (A) et un organohydrogénopolysiloxane (B). La présente invention concerne également un procédé de préparation de la composition. En outre, la présente invention concerne un procédé de préparation d'un article, par exemple un diffuseur de lumière, et un dispositif d'éclairage comprenant le diffuseur de lumière. Enfin, la présente invention concerne un procédé de transmission diffuse de lumière à l'aide du diffuseur de lumière.
