Abstract
The invention describes a color-developing composition that contains at least three major components: (1) a leuco dye or a combination of leuco dyes, (2) an color-developer or a combination of color-developers that can form colored complexes with the leuco dyes, and (3) a desensitizer to temporarily remove the effect of the developer so the leuco dye appears in its colorless form. An optional binder may be included so that the composition may be applied to a substrate as an ink. The ink composition may be applied to synthetic polymeric substrates and other substrates that are incorporated into absorbent articles or personal care products.
