Metal-containing additive, crosslinkable polymer composition, crosslinked polymer material, metal member, and wire harness

A metal member, comprising:

• I. a metal base;
• and
• II. a coating material covering a surface of the metal base, wherein the coating material comprises a crosslinked product of a crosslinkable polymer composition,
• the crosslinkable polymer composition comprising
• i. a metal-containing additive, the metal-containing additive comprising:
• (A) a β-diketonato metal complex;
• and
• (B) a primary alkyl alcohol having 4 to 30 carbon atoms;
• and
• ii. an uncrosslinked organic polymer, wherein the uncrosslinked organic polymer has a substituent capable of forming ionic bonds with metal ions released by heat from the metal-containing additive during crosslinking of the organic polymer, and
• wherein in the crosslinked product of the crosslinkable polymer composition, the organic polymer is crosslinked via metal ions released from the metal-containing additive during crosslinking of the organic polymer.
