  • Composite film and method of manufacturing surface coating material
    Patent number: 6040049
    Abstract: A composite film for forming a resinous coating film on a surface of a to-be-coated material. The composite film has at least one water-soluble resinous coating film, at least one of which is formed on a surface of the composite film which is brought into contact with the surface of the to-be-coated material closely, and a base sheet to which the water-soluble resinous coating film adheres and transmits light therethrough. The water-soluble resinous coating film formed on the surface of the composite film which is brought into contact with the surface of the to-be-coated material closely is hardened in close contact with the to-be-coated material, with water interposed between the water-soluble resinous coating film and the to-be-coated material and adheres to the to-be-coated material to form a water-insoluble coating film. It is preferable that the application amount of the water is in a range of 1.5 g/m.sup.2 -10 g/m.sup.2.
