Abstract

This invention relates to unsubstituted and polymeric leuco colorants for use as consumer product additives to indicate a product function by color change, to make attractive or distinctive visual effects, or to provide latent or delayed color generation. The colorants may be present in a stable, colorless state and may be transformed to an intense colored state upon exposure to certain physical or chemical changes. Alternatively, the colorants may be transformed from one color to another color upon exposure to certain physical or chemical changes. The colored form of the unsubstituted or polymeric leuco colorant may be transient, since the colorant can revert back to its colorless form or its original color after the physical or chemical activation has been removed or changed. Polymeric leuco colorants are typically comprised of at least two components: at least one leuco chromophore component and at least one polymeric component.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application 60 / 900,589, filed February 9, 2007, entitled "Unsubstituted and Polymeric Leuco Colorants For Coloring Consumer Products," the contents of which are hereby incorporated by reference in their entirety. technical field [0003] The present invention relates to unsubstituted polymeric leuco colorants for use as consumer product additives to indicate product functionality through color change, create attractive or unique visual effects, or provide latent or delayed color development. These types of colorants are capable of existing in a stable, substantially colorless state and can be converted to Strong colored state. These types of colorants can also exist in a stable chromogenic state and convert to a different chromonic state when subjected to certain physical or chemical changes. The chromogenic form of an unsubstituted or polymeric leuco colorant m...
