PURPOSE:To prepare the title compsn. which has an improved near-infrared absorptivity while transmitting visible rays relatively well by compounding a styrene resin, a specific copper compd., and a thiourea deriv. and/or a thioamide deriv. CONSTITUTION:100 pts.wt. styrene resin is compounded with a copper compd. selected from the group consisting of those of formula I [wherein R is H or a monovalent group selected from the group consisting of (cyclo)alkyl, aryl, aralkyl, and heterocyclic groups; X is -COO, -SO4, -SO3, -PO4, or -O; and u is 1-4], copper chlorophyll, copper chlorophyllin sodium, and copper bisacetylacetonate and 0.05-50 pts.wt. thiourea deriv. of formula II [wherein R1, R2, and R3 are each H, (cyclo)alkyl, aryl, aralkyl, or 5-or 6-membered heterocyclic] and/or thioamide deriv. of formula III (wherein R4 is R1; and R5 is R1 or alkoxy) to give the title compsn., which is formed into a film or sheet having a thickness of 0.01-10mm. |
