CURABLE COMPOSITION, CURED ARTICLE AND OPTICAL SEMICONDUCTOR DEVICE

摘要

SOLUTION: There is provided a curable composition containing (A) at least one kind of inorganic oxide particle selected from cerium oxide particle and iron (II) oxide particle, (B) polysiloxane having at least 2 alkenyl groups per a molecule and a silicon atom-binding aryl group, (C) polysiloxane having at least 2 silicon atom-binding hydrogen atom per a molecule and (D) a catalyst for hydrosilylation reaction with the content of the inorganic oxide particle (A) of less than 5 pts.mass based on total 100 pts.mass of the polysiloxane (B) and the polysiloxane (C).EFFECT: The curable composition can form a cured article hardly changing a shape even under severe environment such as heat impact or high temperature and high humidity.SELECTED DRAWING: None
