  • Patent number: 7601853
    Abstract: This invention provides a novel class of compounds and compositions and synthetic methods related to lactone antioxidant 3-arylbenzofuranones. The compounds may be useful to prevent yellowing and deterioration of organic materials preferably polymers, such as polyurethane foams as one example. The lactone antioxidants may be polymeric, and may also be liquid or paste in physical form at room temperature. Although it is not necessary for its stabilizing properties, the compositions may, in some species, bear one or more reactive primary OH groups on the polymer chains. The chains may also contain oligomeric oxyalkylene ether and aliphatic ester functional groups, in one embodiment of the invention.

  • Patent number: 7399566
    Abstract: The invention provides novel colored toner and developer compositions containing polymeric colorants. Such compositions may contain poly(oxyalkylene) or poly(alkylester) substituted color chromophores which are attached to relatively long chained ologomers. The color toner and developer compositions of the invention resist color bleeding and aggregation, and may retain their color fidelity over extended time periods. Such color toner compositions are useful in color imaging systems. The invention provides novel compositions that can readily be formulated and manufactured using the polymeric or oligomeric colorants. The toners of the invention may contain charge control agents, thermoplastic resins, colorants, and additives.

  • Publication number: 20070112087
    Abstract: Black polyurethane foams that exhibit higher strength black colorations without the need for concomitant increases in black colorants therein are provided. Such a resultant jetter black foam article is possible through the unexpectedly effective introduction of small amounts of certain toner compounds or combinations that exhibit specific measurable appearance characteristics. Such toners exhibit at least one absorption peak within a specific range of wavelengths (e.g., from about 560 to 610 nm) and specific ranges of half-height bandwidths (from 40 to 130 nm). Furthermore, such a compound or combination of compounds, is preferably liquid in nature (at room temperature) or in dispersion form and may thus be easily incorporated within target polyurethane precursor compositions for admixture with either black pigments (or dispersions thereof), black polymeric (liquid) colorants, or both.

  • Patent number: 7094918
    Abstract: Novel ultraviolet absorbing compounds that are liquid in nature, are low in color (and thus permit use without the concomitant necessity of adding large amounts of other coloring agents to combat such discoloring), and are highly effective in providing protection in wavelength ranges for which previous attempts at low-color ultraviolet absorbers have failed are provided herein. Such compounds provide such excellent, inexpensive, and beneficial protection from ultraviolet exposure within various media, including, but not limited to, clear thermoplastics. The particular compounds are generally polymeric in nature including various chain lengths of polyoxyalkylenes thereon and are liquid in nature to facilitate handling and introduction within the target media. In addition, such ultraviolet absorbers also exhibit extremely low migratory properties thereby providing long-term protective benefits to the target media as well.

  • Publication number: 20060069174
    Abstract: Polyurethane foam is disclosed having improved flame retardancy, charring, and intumescent properties. The foam is prepared from a reaction mixture comprising at least one isocyanate or diisocyanate, one blowing agent, one surfactant, one catalyst, and one reactive hydroxyl-terminated oligomeric liquid melamine derivative. The resulting foam provides substantial resistance to burning. A melamine-derived compound having at least alkyl or alkoxy groups, with hydroxy (—OH) termination(s) have proved to be particularly useful in connection with polyurethane foam.
