Abstract:
A transparent resin composition with near infrared absorption characteristics which comprises 100 parts by weight of a transparent thermoplastic resin, from about 0.01 to about 2 parts by weight of (1) a thiuram compound of the general formula (A): ##STR9##in which R.sub.1 and R.sub.2 are the same or different and represent monovalent groups selected from the group consisting of hydrogen, alkyl, cycloalkyl, aryl and aralkyl, or form together a ring, and m and n are integers of 1 to 4, (2) a metal dithiocarbamate compound of the general formula (B): ##STR10##in which R.sub.3 and R.sub.4 are the same or different and represent monovalent groups selected from the group consisting of hydrogen, alkyl, cycloalkyl, aryl and aralkyl, or form together a ring, M is Co, Ni, Fe, Na or K, and p is an integer of about 1 to about 4 equivalent to the valency of M, or a mixture of (1) and (2), and from about 0.01 to about 2 parts by weight of a copper compound of the general formula (C):X.sub.q Cu (C)in which X is sulfur, fluorine, chlorine, --CN, phthalocyanyl, sodium cholorphyllin, bisacetylacetate or R.sub.5 --Y (wherein R.sub.5 is a monovalent group selected from the group consisting of hydrogen, alkyl, cycloalkyl, aryl, aralkyl and Y is --COO, --SO.sub.4, --SO.sub.3, --PO.sub.4 or --O), and q is 1 or 2.
