ABSTRACT:
A process for recycling a thermoplastic resin covered with a thermosetting-resin paint film includes the steps of decomposing the paint film by bringing the thermoplastic resin covered with the paint film into contact with a paint-film-decomposing agent in a molten state, and removing decomposed products, resulting from the paint film and the paint-film-decomposing agent, and the residual paint-film-decomposing agent by degassification to prepare a recycled resin. The paint-film-decomposing agent can be primary amines and/or secondary amines having a boiling point of 250.degree. C. or less, or being decomposed at 250.degree. C. or less, or can be tertiary amines and/or quaternary amines having a boiling point of 250.degree. C. or less, or being decomposed at 250.degree. C. or less to which water and/or alcohols is added.
