<P>PROBLEM TO BE SOLVED: To provide a curable composition excellent in moldability and having near-infrared ray absorptivity, and its cured product; and to further provide a cured product which has reflow resistance and hence is useful as a near-infrared ray absorbing optical element. <P>SOLUTION: The curable composition has near-infrared ray absorption capacity and comprises: an organic compound containing a carbon-carbon double bond reactive with an SiH group; a hydrosilylating catalyst; an SiH group-containing silicon compound; and at least two compounds selected from a quarterilene-based compound, a phthalocyanine-based compound and a naphthalocyanine-based compound. Both of the composition and its cured product are useful for near-infrared ray absorbing optical elements. <P>COPYRIGHT: (C)2011,JPO&INPIT |
