Abstract
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° to 300° 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.
