Furthermore, the method of coating the metal with a hydrophilic resin cannot protect the metal from corrosion. Furthermore, even in random copolymers of hydrophilic monomers and hydrophobic monomers, it is difficult to achieve both hydrophilicity and corrosion resistance.

するに至った。When this composition was coated on a metal surface, it was confirmed that it had excellent adhesion to metal and also had corrosion resistance. After that, as a result of further intensive studies, we found that a block or graft copolymer consisting of a hydrophilic copolymer part into which a specific crosslinkable functional group was introduced and a hydrophobic copolymer part into which a specific crosslinkable functional group was introduced was created. By using an activator in combination and adding a metal chelate type crosslinking agent, the coating formed on the surface of the metal material from the composition has a dramatically more sustainable hydrophilicity than expected with conventional technology. The present inventors have found that the present invention is excellent in adhesion to the surface of metal materials and wear resistance, and that the above-mentioned conventional problems can be significantly improved.

向上する。[Function] By employing the above means, the hydrophilic polymer portion of the block copolymer or graft copolymer and the surfactant become compatible, and the block or graft copolymer uniformly disperses the surfactant. At the same time, the metal chelate type crosslinking agent exhibits corrosion resistance by preventing water from penetrating into the coating through self-crosslinking or crosslinking with the functional groups of the copolymer. In the coating formed from this composition, the hydrophilic polymer portion of the block or graft copolymer acts as an anchor for the surfactant, firmly fixing the surfactant in the coating. When moisture adheres to the film, the surfactant gradually bleeds from inside the film, resulting in a synergistic effect between the function of the hydrophilic polymer portion of the block or graft copolymer and the function of the bleeding surfactant. Hydrophilic performance and hydrophilic sustainability are dramatically improved.
