- Colorant compounds, intermediates, and compositions
-
Colorants are disclosed that exhibit high color strength, bright shades, and high thermal stability. Such compounds have found application as colorants for polyethylene terephthalate (“PET”). Potential end uses include disperse dyes, non-warping pigments, decolorizable colorants, and the like. Compounds and methods for synthesis include benzodifuranone related compounds, benzene centered lactones, benzene centered lactams; benzene-centered thiolactones; naphthalene-centered lactones; naphthalene-centered lactams; naphthalene-centered thiolactones; anthraquinone-centered lactones; anthraquinone-centered lactams; anthraquinone-centered thiolactones; anthracene-centered lactones; anthracene-centered lactams; anthracene-centered thiolactones; hetero-aromatic-centered lactones; hetero-aromatic centered lactams and hetero-aromatic centered thiolactone compounds, and the like. Furthermore, resins such as PET or other polymeric resins containing the compounds are disclosed.
