A composition includes a polymer and a solvent. The polymer includes a group (X) which is at least one selected from the group consisting of: a group including at least two cyano groups; a group including B(OR).sub.2; a group including PO(OR).sub.2; and a group including P(OR).sub.2. Each R independently represents a hydrogen atom or a monovalent hydrocarbon group having 1 to 10 carbon atoms. The polymer preferably includes the group (X) at an end of a main chain thereof or at an end of a side chain thereof.

A conductive structure is provided. The conductive ink composition includes a silver complex formed by mixing a silver carboxylate, at least one dissolving agent that dissolves the silver carboxylate, and a catalyst. The catalyst includes an amine that decarboxylates the silver carboxylate to make the conductive ink composition. The catalyst decarboxylates the silver carboxylate at a temperature of 100 C. or less. An ink composition comprising a metallic salt with a sterically bulky counter ion and a ligand is also provided. An ink composition for making a conductive structure, comprising a reducible metal complex formed by mixing: a reducing agent, wherein the reducing agent is dissolved in a dissolving agent; and at least one metal salt or metal complex comprising a Group 4, 5, 6, 7, 8, 9, 10, 11, or 12 metal, wherein the reducing agent reduces the metal to forms the conductive structure is further provided.
