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.

摘要:
The present invention provides a coating material for metal wherein a thin coating film without pinholes having excellent corrosion resistance, retort resistance, impact resistance, processing resistance, abrasion resistance, adhesiveness to a metal, flavor preservability for contents etc can be formed when applying on a metal plate or a metallic container, and a metallic container on which the coating material is applied. The present invention relates to a coating material for metal comprising thermoplastic resin particles having an average primary particle size of 10 to 1000 nm obtained by cooling a solution of the thermoplastic resin, and a process for preparing the coating material for metal comprising steps of (a) obtaining a solution wherein a thermoplastic resin is dissolved into an organic solvent, (b) obtaining a dispersion of particles of the thermoplastic resin having an average primary particle size of 10 to 1000 nm by cooling the solution, (c) separating particles from the dispersion and (d) dispersing the separated particles in a solvent.
