PURPOSE: To obtain a laminated copper plate, preventing the surface of copper plate from being scratched or contaminated and easy to remove a coating layer, by a method wherein the coating layer, consisting of a coating material made up mainly of water-soluble polymerized compound provided with a specified chemical structure, is formed on the surface of the copper plate.
CONSTITUTION: A coating layer, consisting of a coating material made up mainly of water-soluble polymerized compound constituted of a repeating unit shown by a formula, is formed on the surface of a copper plate easy to prevent scratch or contamination against the surface of the copper plate or to coat it, so that removal of a formed coating film can be effected simply. In the formula, A is a unit constituted of the repeating of (CH2CH2O) and (CH2R1.CHO), R1 is hydrocarbon group, X is the residue of organic compound having two active hydrogen groups and R2 is the residue of dicarboxylic acid compound group or the residue of di-isocyanate compound.
