COMPOSITION FOR NEAR-INFRARED RAY ABSORPTION MEMBER AND NEAR-INFRARED RAY ABSORPTION MEMBER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a composition for a near-infrared ray absorption member that absorbs largely and widely the near-infrared region, does not impair the near-infrared absorption performance during the production process of a liquid crystal device or the like and is excellent in heat resistance and to provide a near-infrared ray absorption member using the composition.;SOLUTION: The composition for a near-infrared ray absorption member includes (A) a substituted benzenedithiol nickel complex represented by formula (1), (B) a polyfunctional (meth)acrylic monomer and (C) a (meth)acrylic acid ester copolymer, and the near-infrared ray absorption member uses the composition. In formula (1), R denotes a cyclic amino group such as a dialkylamino group, a substituted or unsubstituted morpholino group, a substituted or unsubstituted piperidino group, a substituted or unsubstituted pyrrolidino group, a substituted or unsubstituted thiomorpholino group, a substituted or unsubstituted piperadino group or the like, an aryl group or an alkyl group and A denotes an ammonium ion or a phosphonium ion.;COPYRIGHT: (C)2010,JPO&INPIT
