Coating material for coating metal cans, and metal can coated with same

摘要

Provided are: a coating material for coating metal cans, which has excellent retort resistance and is capable of forming a coating film that is free from pinholes, while having excellent strength, solvent resistance, impact resistance and processability; and a metal can which is coated with this coating material. This coating material for coating metal cans contains thermoplastic resin particles and is characterized in that the thermoplastic resin is a resin that contains 10% by mass or more of a polybutylene naphthalate resin (PBN). It is preferable that the particles have an average primary particle diameter within the range from 10 nm to 1,000 nm.
