Fibers and other articles of manufacture have a near-infrared fluorescent compositions, useful as identification markers, attached to the fiber or article of manufacture by a cross-linking agent. The marker compositions may contain other ingredients, such as antistats, antimicrobials and/or other additives mixed therein. Effective cross-linking can be obtained by several means, including heating in an oven, air-drying, etc. A method for marking the fiber or article includes contacting the material with a cross-linking agent and a near-infrared fluorescing compound having an absorbance of illumination radiation ranging from about 650 nm to about 100 nm. |
