Compounds for reducing background color in color changing compositions |
| abstract |
Aspects of the present invention include color changing compositions having: a combination of a coupler and a color developer that switches from a first color state to a second color state upon application of an applied stimulus, and an appropriate amount of a copolymer , which is sufficient to eliminate the background color of the combination of coupler and color developer during the transition from the first color state to the second color state. Also disclosed are methods of making the color changing compositions of the present invention and apparatus for using the same. |
