    Abstract: Disclosed are novel anthraquinone compounds containing tetra-p-phenylenediamine substituents, particularly useful in molding type polyester compositions and possessing strong infrared absorptivity. This property renders these compounds attractive as additives for increasing the infrared energy absorptivity of polyesters either from high intensity quartz lamps or from certain laser systems. These compounds are particularly useful in bottle polyester material for increasing the blow-mold parison reheat rate, and in the printing of plastic articles with lasers.
