A composition which comprises a thiourea derivative of Formula [1] or [2]:
and a copper compound, may be used to prepare a near-infrared resin material which has a wide absorption in the near-infrared region. Typical examples of the dimerized thiourea derivative are 4,4'-di(benzylthiocarbamoyl)-aminodiphenylmethane, 4,4'-di(benzylthiocarbamoyl)-aminodiphenylhexafluo- ropropane, and 1,4'-di(dibenzoylthiocarbamoylamino)-2,5-dimethylbenzene and typical examples of the copper compound are copper stearate and copper β-acryloyloxypropylhydrogenphthalate.
