This invention provides transparent resin compositions of polycarbonate, polyester, methacrylic, styrene, polyvinyl chloride, polyolefin, and polyamide resin, having the advantageous effects of efficiently absorbing near infrared radiation (780-1800 nm) and efficiently transmitting visible light (380-780 nm). The invention provides transparent resin compositions with excellent near infrared absorption characteristics comprising 100 parts by weight of a transparent thermoplastic resin, about 0.01 to about 2 parts by weight of a specific thiuram compound and/or a specific metal dithiocarbamate compound, and about 0.01 to about 2 parts by weight of a specific copper compound. It also provides transparent resin compositions with excellent near infrared absorption characteristics comprising 100 parts by weight of a transparent thermoplastic resin, about 0.01 to about 2 parts by weight of a specific copper dithiocarbamate compound, and about 0 to about 2 parts by weight of a specific copper compound.
