<p>A precoated metal sheet with excellent press formability which has on one or each side thereof a chemical-treatment coating layer comprising as solid components at least either of tannin and tannic acid, a silane coupling agent, and finely particulate silica and a resin coating layer formed on the chemical-treatment coating layer and comprising 100 parts by weight of a resin on a solid basis and 1 to 140 parts by weight of an aluminum phosphate pigment. The chemical-treatment coating layer preferably further contains a polyester resin, and the resin coating layer preferably further contains an anticorrosive pigment. Aluminum dihydrogen tripolyphosphate is optimal as the aluminum phosphate pigment. Calcium ion-exchangeable silica is optimal as the anticorrosive pigment.</p> |
