<P>PROBLEM TO BE SOLVED: To provide a curable resin composition tablet which provides a cured product striking a balance between handling ability at normal temperature and fusibility at high temperature and which has high light ray reflectance and good resistance against heat and light. <P>SOLUTION: The curable resin composition contains, as essential ingredients, (A) a compound that contains at least two carbon-carbon double bonds, which are reactive with an SiH group, in each molecule, (B) a compound that contains at least two SiH groups in each molecule, (C) a hydrosilylation catalyst, (D) a white pigment, and (E) an inorganic filler. At least one of the components (A) and (B) is liquid having viscosity of ≤50 Pa per second at 23°C. The total content of the components (D) and (E) is 70-95 wt.%. Particles of ≤12 microns accounts for ≥40 vol.% of the total of the components (D) and (E). <P>COPYRIGHT: (C)2012,JPO&INPIT |
