Abstract
A curable organopolysiloxane composition comprises at least the following components: an organopolysiloxane (A) represented by the following general formula: RSiO(RSiO)SiR(where Ris a monovalent hydrocarbon group, and 'm' is an integer from 0 to 100); an organopolysiloxane (B) represented by the following average unit formula: (RSiO)(RSiO)(RSiO)(where Ris a monovalent hydrocarbon group, and 'a', “b”, and “c” are specific numbers); an organopolysiloxane (C) having in one molecule on average at least two silicon-bonded aryl groups and on average at least two silicon-bonded hydrogen atoms; and a hydrosilylation-reaction catalyst (D); is characterized by good fillability and curability and that, when cured, forms a cured body that possesses a high refractive index, high light transmissivity, and strong adhesion to various substrates.
