Abstract
Abstract A security coating for business documents printed using noncontact as well as impact printing devices is provided which enhances the adhesion of toner particles and/or ink to a document substrate. Other security features may be also be added to the coating to provide a dual-function coating which also provides visible evidence of tampering, either by the application of solvents, mechanical abrasion, heat, or when pressure is applied.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
142 words
A coated sheet or web useful with noncontact printers using toner particles or impact printers using ink-containing ribbons comprising a sheet or web substrate, and a coating on at least a portion of one surface of said substrate which enhances the adhesion of said toner or ink to the coated surface of the substrate, said coating comprising a polymeric matrix, wherein after said toner or ink has been fixed onto said web by printing, said toner or ink is retained on said coated surface in an amount greater than the amount of toner or ink retained on an uncoated surface of said substrate after said coated and uncoated surfaces have been subjected to a tape test, and wherein said coating is present on said substrate on a dry weight basis in an amount of between about 0.3 to 2.0 lbs per ream.
Claim 2
Dependent Claim
142 words
A coated sheet or web useful with noncontact printers using toner particles or impact printers using ink-containing ribbons comprising a sheet or web substrate, and a coating on at least a portion of one surface of said substrate which enhances the adhesion of said toner or ink to the coated surface of the substrate, said coating comprising a polymeric matrix, wherein after said toner or ink has been fixed onto said web by printing, said toner or ink is retained on said coated surface in an amount greater than the amount of toner or ink retained on an uncoated surface of said substrate after said coated and uncoated surfaces have been subjected to a tape test, and wherein said coating is present on said substrate on a dry weight basis in an amount of between about 0.3 to 2.0 lbs per ream.
Claim 3
Dependent Claim
183 words
A coated sheet or web useful with noncontact printers using toner particles or impact printers using ink-containing ribbons comprising a sheet or web substrate, and a coating on at least a portion of one surface of said substrate which enhances the adhesion of said toner or ink to the coated surface of the substrate, said coating comprising a polymeric matrix, wherein after said toner or ink has been fixed onto said web by printing, said toner or ink is retained on said coated surface in an amount greater than the amount of toner or ink retained on an uncoated surface of said substrate after said coated and uncoated surfaces have been subjected to a tape test, said polymeric matrix including therein a chromogen and an agent capable of activating said chromogen to form a visible color when said sheet or web is subjected to attempted tampering or alteration through the application of solvents, mechanical abrasion, or heat, and wherein said coating is present on said substrate on a dry weight basis in an amount of between about 0.3 to 2.0 lbs per ream.
