A hardenable coating composition, comprising: a. a resin binder, comprising: a. a reaction product of an epoxy-containing polymer with a compound containing phosphorous acid groups, the reaction product having reactive functional groups, b. a hardening agent having functional groups reactive with the functional groups of (i); C. an electroconductive pigment dispersed in (a), such that the weight ratio between (b) and (i) is within the range of 0.5 to 9, 0: 1, the hardenable coating composition being characterized because when deposits and hardens on a metal substrate, the hardened coating is weldable. |
