  Aspects of the invention include color change compositions having a color former and color developer composition that transitions from a first color state to a second color state upon application of an applied stimulus and an amount of a copolymer sufficient to eliminate background color of the color former and color developer composition during transition from the first color state to the second color state. Methods for preparing and devices employing the color change compositions of the invention are also described.

  本发明的各个方面包括变色组合物，该组合物具有在施加外加刺激时从第一颜色状态过渡到第二颜色状态的显色剂和足够量的共聚物，以便在从第一颜色状态过渡到第二颜色状态期间消除显色剂和显色剂组合物的背景色。此外，还描述了制备本发明变色组合物的方法和使用本发明变色组合物的装置。
