摘要:
The present invention provides a highly retort-resistant metal can coating material that can form a pinhole-free coating that excels in strength, solvent resistance, impact resistance, processability, etc., and a metal can coated with the coating material. The metal can coating material contains particles of a thermoplastic resin, and the thermoplastic resin contains at least 10 mass% of a polybutylene naphthalate resin (PBN). Preferably, the particles have an average primary particle diameter in the range from 10 nm to 1000 nm.
