Abstract
An article having a surface comprising an olefin polymer is marked with indicia using an ink comprising a binder capable of substantially complete cure at a temperature of about 100.degree. to 300.degree. C. for less than about 10 minutes and then heated to cure the binder. The indicia are permanent, e.g. are resistant to being rubbed off and are solvent resistant. Heat-recoverable marker sleeves having such permanent indicia are particularly useful for marking wires, e.g. in aircraft harnessing.
