PROBLEM TO BE SOLVED: To provide a resin coated galvanized steel sheet excellent in deep drawing workability, solvent resistance and corrosion resistance. ;SOLUTION: A resin coated galvanized steel sheet excellent in deep drawing workability, solvent resistance and corrosion resistance is obtained by applying a resin coating film with 0.5-5 μm film thickness having a composition which consists as a man component of an urethane based resin (A) containing a polycarbonate bond in the main chain and an alkoxysilyl group in the branched chain and having ≥100 MPa dynamic storage elastic modulus (E') of the heat hardened coating film at 150°C, 5-30 wt.% lubrication function imparting agent (B) per the solid portion of the resin and 1-30 wt.% a silica particle (C) per the solid portion of resin on a galvanized steel sheet, after a chromate coating film is formed.;COPYRIGHT: (C)1998,JPO
