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.
Claims15
A heat recoverable marker sleeve comprising:
- (a) a heat recoverable article having a surface comprising an olefin polymer and
- (b) permanent indicia on said surface of said article formed of a substantially completed cured ink composition comprising:
- (i) a binder capable of adhering to said surface and capable of substantially complete cure when heated to about 100.degree. to about 300.degree. C. in less than about 10 minutes;
- and
- (ii) a pigment.
A method of forming permanent indicia on a heat recoverable marker sleeve which comprises:
- (a) selecting a heat recoverable article having a surface comprising an olefin polymer;
- (b) forming indicia on the surface thereof with an ink comprising:
- (i) a binder capable of adhering to said surface and capable of substantially complete cure when heated to about 100.degree. to about 300.degree. C. in less than about 10 minutes;
- and
- (ii) a pigment;
- and
- (c) heating the article to substantially completely cure said binder, thereby rendering said indicia permanent.
