    摘要: Provided are coating film removing method and a coating film removing equipment that can efficiently remove a coating film from a surface of a coated film including a coating film containing a water-soluble resin by using a very small amount of solvent. A method for removing a coating film from a coated film according to the present invention is a method for removing a coating film from a coated film including a coating film containing a water-soluble resin on at least one side of a base film. The method is characterized in that a cleaning liquid in the form of droplets is supplied to a surface of the coating film, the cleaning liquid is retained in the form of droplets on the surface of the coating film, and then the coating film containing the cleaning liquid is removed off from the coated film.

    摘要: Provided is a method for forming a multi-layer coating film which makes it possible to form a multi-layer coating film which exhibits excellent smoothness and luster. The present invention forms, on a cured electrodeposited coating film formed on a steel plate, a first colored coating film comprising a first coloring coating material (Pl), a second coating film comprising a second aqueous coating material (P2) having specific viscometric properties, a third colored coating film comprising a third aqueous coloring coating material (P3) which has a specific coating material solid content concentration (NV P3 ) and contains a lustrous pigment (B P3 ), and a clearcoat film comprising a clearcoat material (P4). The present invention simultaneously cures the formed multi-layer coating film by heating.
