<p>A coated metal plate for positive electrode cans of alkaline dry cells, produced by coating a metal plate first with a chromate coating, preferably one containing carbon black, and then with a coating based on at least one of an epoxy resin, an epoxy/acrylic resin and a polyester resin, each containing carbon black having a purity of 95 % or above, an aspect ratio of 50 or above and an oil absorption of 250 ml/100 g or above as measured by using powdery graphite and/or DBP having an average particle diameter of 50 νm or less, and optionnally further containing a cross-linking agent. The positive electrode can be produced merely by drawing the coated plate.</p> |
