Electrically conductive resin composition

Claim 1

An electrically conductive resin composition comprising: (i) a resin; (ii) at least one metallic powder selected from the group consisting of nickel, copper, iron, aluminum, and alloys thereof; (iii) at least one diphosphonic acid derivative having the formula (I): ##STR4## wherein R' represents alkyl having 1 to 18 carbon atoms, phenyl or alkylphenyl, the alkyl in alkylphenyl having 1 to 8 carbon atoms, and M 1 to M 4 each independently represent hydrogen or a cation; (iv) at least one hydroxyl-containing compound selected from the group consisting of the compounds having the formulas (II), (III), (IV), (V), and (VI): ##STR5## wherein R 2 represents alkyl having 4 to 22 carbon atoms, aryl having 6 to 10 carbon atoms, alkylaryl having 7 to 19 carbon atoms; X and Y independently represent ##STR6## A, B, C, and D each independently represent ##STR7## i is 0 to 40, and j and k are independently 1 to 40; wherein the weight ratio of the component (i)/the component (ii) is 30/70 to 85/15 and the amounts of the components (iii) and (iv) are 0.5 to 7.9 parts by weight and 0.08 to 7.5 parts by weight, respectively, based on 100 parts by weight of the component (i) and (ii).
