COATED METAL PLATE EXCELLENT IN PROCESSABILITY AND SCRATCH RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a coated metal plate made excellent in both conflicting processability and scratch resistance by dispersing hard thermosetting organic resin particles in the resin coating film formed on the surface of a metal plate. SOLUTION: In the coated metal plate wherein spherical thermosetting organic resin particles P harder than the resin coating film R are dispersed in the organic resin coating film R with a pencil hardness of HB or less formed on the surface of the metal plate M, the maximum particle size of the thermosetting organic resin particles P is below three times the average film thickness (h) of the resin coating film R and 2-20 mass % of the thermosetting organic resin particles P having a particle size larger than the average film thickness of the resin coating film R are dispersed in the resin coating film R. The protruded parts of the thermosetting organic resin particles P dispersed in the resin coating film R are covered with the thin film of the resin coating film R. The processability of the coated metal plate is charged with the soft base resin coating film R and the abrasion resistance and scratch resistance thereof are charged with the hard particles P in the coating film to obtain the coated metal plate having both characteristics.
