<p>Resin-coated steel sheets which have excellent workability in drawing and ironing even at a normal temperature without preheating, and which give, by drawing and ironing, DI cans having resin coating satisfactory in adhesion, corrosion resistance, and external appearance. The sheets comprise a steel sheet tin-coated on one side and chromate-treated on the other side, the chromate-treated side being further coated with a resin composition composed of a thermoplastic polyester resin prepared by a thermal fusion reaction of 95 to 5 % by weight of a crystalline polyester and 5 to 95 % by weight of non-crystalline polyester and having an alloying ratio, of 5 to 50 %. The sheets may be tin-coated on both sides, one of which is further coated with the above resin composition or a non-crystalline resin and further the above resin composition, or the above resin composition and further a crystalline polyester resin.</p> |
