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.

Abstract: Colorant compositions are useful for a wide variety of product applications. For example, colorants are used in tinting of polymers, providing colors to aqueous solution(s), and affording color to solid or semi-solid products such as detergents. Disclosed herein are colorant compositions having a triphenylmethane (“TPM”) derived structure having improved stability to alkaline conditions. Thus, the colorant compositions resist decolorization, even at relatively high pH levels. The colorant compositions of the invention are useful as applied in polyolefins, such as polypropylene and polyethylene, as examples. These colorant compositions also may be employed in thermoplastics, such as PET, for example.

Abstract: Chemical sensor compositions and methods for quantifying analytes are described. The chemical sensors include analyte-binding moieties and reporter moieties covalently attached to a framework including two trityl groups connected by a linear spacer such as ethyne or butadiyne. The sensors chelate an analyte across the acetylene axis of the molecule to stabilize the molecule in an eclipsed rotamer conformation. This conformation causes the sensors to emit a measurable signal.
