Abstract
The present invention comprises an improved organic composite-plated steel plate which is obtained by applying a thermosetting resin to a chromate-coated alloy-plated steel plate and curing this, wherein, various aqueous resin compositions having the form of basic coating film formation components, such as, for example, aqueous vinyl modified epoxy ester resins, or aqueous vinyl modified epoxy ester resin / blocked isocyanate compound-types, or aqueous vinyl modified epoxy ester resin / blocked isocyanate compounds / colloidal silica-types, are used as the thermosetting resin described above. In accordance with the present invention, it is possible to provide an organic composite-plated steel plate which is novel and has extremely high applicability in a form in which an aqueous resin (composition) for organic composite coating, which has superior adhesion with adhesives, superior continuous welding properties, superior post-working corrosion resistance, and superior electro-deposition coating properties, and moreover, has superior coating material adhesion and corrosion resistance, and the coated surface of which, after electro-deposition coating, has particularly superior shininess (smoothness), and which furthermore has superior rust resistance and does not use large amounts of organic solvent, is pre-coated onto a metallic material.
