Abstract
The present invention relates to a method of producing activated color regions in a web substrate where activated color regions are formed coinciding with deformed regions. The method includes providing a web substrate having an activatable colorant and producing a first activated color region therein. The web substrate is mechanically deformed to produce at least one deformed region in the first activated color region such that a second activated color region is produced coinciding with the at least one deformed region.
Claims16
A method of producing color change in a web substrate, the method comprising the steps of:
- a. providing a web substrate comprising an activatable colorant;
- b. applying a first external stimulus to the web substrate to activate the activatable colorant producing a first activated color region in the web substrate;
- c. mechanically deforming the first activated color region of the web substrate to produce a second external stimulus comprising deforming the first activated color region of the web substrate producing at least one deformed region therein wherein a second activated color region is produced coinciding with the at least one deformed region;
- and
- d. wherein the first external stimulus comprises ultraviolet light and the second external stimulus comprises heat induced by strain.
A method of producing color change in a web substrate, the method comprising the steps of:
- a. providing a web substrate comprising an activatable colorant;
- b. applying a first external stimulus to the web substrate to activate the activatable colorant producing a first activated color region in the web substrate;
- c. mechanically deforming the first activated color region of the web substrate to produce a second external stimulus comprising deforming the first activated color region of the web substrate producing a plurality of deformed regions therein wherein a plurality of second activated color regions are produced coinciding with the plurality of deformed regions;
- and
- d. wherein the first external stimulus comprises ultraviolet light and the second external stimulus comprises heat induced by strain.
