PURPOSE:To obtain the title composition which can give a molding having excellent properties and having a marble-like flow pattern even when it is molded with a screw-inline injection molding machine, by mixing a colored acrylonitrile/styrene copolymer resin with a colored polybutylene terephthalate resin. CONSTITUTION:80-99.5pts.wt. colored acrylonitrile/styrene copolymer resin (A) of an acrylonitrile component content of 5-80wt.% and an average MW of 20,000-300,000 is mixed with 20-0.5pts.wt. colored polybutylene terepthalate resin (B) obtained by polymerizing terephthalic acid with butanediol and having a flow rate of 0.2X10<-2>-9.5X10<-2>cm<2>/sec (as measured through an orifice of a diameter of 1mm and a length of 10mm at 250 + or -5 deg.C under a load of 50kg) to obtain the title composition. This composition is injection-molded with a screw-inline injection molding machine.
