The present invention presents a resin composition for cleaning a plastics-processing machine, containing a tracer substance and a thermoplastic resins, wherewith the plastics-processing machine is cleaned. After the plastics-processing machine finishing with processing of a resin is cleaned with the resin composition, the resin composition remaining in the processing machine is discharged with a subsequent resin. The residue of the said resin composition is checked by detecting fluorescence on the surface of a molding after the molding containing the subsequent resin is obtained in the discharging process of the said resin composition remaining in the processing machine. |
