  • Patent number: 7514154
    Abstract: A resin-coated steel plate obtained by providing, on at least one surface of the steel plate, (i-1) an alloy layer of iron and at least one metal selected from tin, zinc and nickel or (i-2) a tin-plated layer containing tin in an amount of not smaller than 0.5 g/m2, (ii) a silane coupling agent-treated layer, and (iii) a thermoplastic polyester resin layer in this order from the side of the steel plate. Despite not containing chromium, the resin-coated steel plate exhibits excellent work adhesion properties between the steel blank and the organic resin film even when the thickness is reduced due to a severe working and even at portions subjected to severe working such as flanging and necking. By press-forming the resin-coated steel plate, there are obtained cans featuring excellent corrosion resistance and being adapted to containing even highly corrosive contents.
