The present invention addresses the problem of providing: a metal plate coating material with which it is possible to form a coating film that has extremely high storage stability, that does not exhibit yellowing, and that is not prone to staining with rain streaks; and a method for producing a coated metal plate using the metal plate coating material. The metal plate coating material for solving the problem contains: at least one of a mixture of a fluorine-containing resin and a (meth)acrylic resin and a copolymer of a fluorine-containing monomer and a (meth)acrylic group-containing monomer; a silicone resin; and a zinc carboxylate salt catalyst.

Metal plate coating material and coated metal plate production method using same

The present invention addresses the problem of providing a painted metal plate having rain-streak-stain resistance and a good appearance, and a method for producing the same. To solve this problem, the method for producing a painted metal plate includes a step for forming a coating by applying a paint containing a silicone resin and a fluorine-containing resin to the surface of a metal plate and curing the paint, and a step for performing flame treatment on the coating. The silicone resin contains 5 to 50 mol % of a silanol group with respect to the total molar mass of Si atoms.
