Abstract
The present invention is a phenol compound represented by the following general formula (1A). This phenol compound makes it possible to provide a phenol compound as an additive for a conductive paste composition having a small decrease in electric conductivity in repetitive elongations and shrinkages and excellent printing processability, a conductive paste composition containing the additive, and a conductive wire made by using the conductive paste composition.

1-17. (canceled)
A phenol compound represented by the following general formula (1A),
- wherein R1 represents a hydrogen atom, a halogen atom, a cyano group, or a hydroxyl group;
- Az represents a linear, branched, or cyclic (ka+2)-valent hydrocarbon group or fluorinated hydrocarbon group having 1 to 20 carbon atoms, and —CH2— constituting the (ka+2)-valent hydrocarbon group is optionally substituted with —O—, —C(═O)— or —Si(R2R3)—;
- each of R2 and R3 is a linear, branched, or cyclic alkyl group having 1 to 6 carbon atoms, or a phenyl group;
- each Xf independently represents a hydrogen atom, a halogen atom, a linear, branched, or cyclic monovalent hydrocarbon group having 1 to 10 carbon atoms optionally substituted with a fluorine atom, an alkoxy group having 1 to 10 carbon atoms optionally substituted with a fluorine atom, or an electron-withdrawing group;
- Z represents a single bond or an oxygen atom;
- each of ring ZZ independently represents an aromatic monocyclic or polycyclic ring having 5 to 20 carbon atoms;
- each carbon atom of the ring ZZ is optionally substituted with a nitrogen atom, an oxygen atom, or a sulfur atom;
- “ka” represents an integer of 0 to 2;
- “kb” and “kd” each represent 1 or 2;
