Abstract:
The present invention relates to dibenzylidene sorbitol ("DBS")-based compounds. The compounds of this invention are particularly advantageous in that they are characterized by one or more of improved transparency (reduced haze), reduced yellowing and/or improved organoleptics (taste). According to one embodiment, the present invention provides a disubstituted DBS-based compound having an allyl group or a propyl group substituted on the first carbon of the sorbitol chain. The present invention also relates to compositions comprising such DBS-based compounds and methods for using them.
Abstract:
Substituted alditol or carbohydrate compounds having a specified general formula (I) are provided. A. method for synthesizing such substituted alditol or carbohydrate compounds is also provided. wherein n is 0, 1, or 2; and R is an alkenyl group having 5 or more carbons.
Abstract:
An acetal compound may be formed by the method of reacting a substituted or unsubstituted benzaldehyde, a polyhydric alcohol, and an at least one acid catalyst at ambient temperatures, in a homogenous reaction media in the presence of at least one water miscible organic solvent. The molar ratio of the acid catalyst to the benzaldehyde may be less than about 0.6 to 1, respectively, of acid catalyst to benzaldehyde.
Abstract:
An acetal-based composition useful as a nucleating, gelling, thickening or clarifying agent is disclosed. The composition may be synthesized or provided in many different forms, including multicarbon diacetals formed from carbohydrates. Once synthesized, the compound may be employed as an additive in a plastic composition, such as (for example) a polypropylene copolymer. Co-additives may also be employed. Several aryl structures may reside upon the hydrocarbon chain backbone. One structure of such an acetal-based composition is a modified sorbitol with one or more aryl groups and at least one substituted group upon a terminal carbon in the chain.

Abstract:
An inventive blue colorant comprising a chromophore having at least one hydroxy group-terminated polyester chain attached, through a suitable alkylamino linking group (or groups), to the 1- position, the 4- position, or both, of an anthraquinone backbone is provided. Such colorants exhibit excellent amine/base stability and thermal stability, effective colorations, excellent low extraction rates, and high lightfastness levels, particularly when incorporated within certain media and/or on the surface of certain polyurethane substrates. The polyester chain or chains can be conveniently tailored to increase the solubility or compatibility in different types of polyurethane resin precursors thereby permitting the introduction of such excellent coloring chromophores within diverse polyurethane media and/or or diverse polyurethane substrates as well as provides a liquid colorant which facilitates handling. Compositions and articles comprising such inventive colorants are provided as well as methods for producing such inventive colorants.
Abstract:
Novel coated substrates comprise a substrate and a coating thereon. The coating comprises a polymeric component and a colorant compound. The colorant compound is produced by reacting an isocyanate compound and an active hydrogen-terminated colorant.
