Patent number: 8871922Abstract: A molecule possessing a primary or secondary amino group and an additional functionality capable of providing a novel or improved property to a cellulose material has been permanently attached to the cellulose material in aqueous media using a water-soluble carbodiimide as the coupling agent/activator. One such molecule is 5-aminofluorescein (abbreviated as “A-fluo”) and one such cellulose material is a papermaking pulp. Papers made from a pulp furnish containing, for example, 0.01 wt. % of the “A-fluo”-attached pulp show an embedded marker feature authenticable upon UV or visible light excitation. The “A-fluo”-attached pulp can also be used for the marking and identification of a pulp furnish.Type: GrantFiled: March 17, 2010Date of Patent: October 28, 2014Assignee: FPInnovationsInventors: Thomas Q.
