    • A urethane acrylate composition includes a resin system and a catalyst system. The resin system includes a urethane acrylate adduct including a reaction product of an isocyanate component and a functionalized acrylate reactive with the isocyanate component. The resin system also includes a first metal salt and a peroxide. The catalyst system includes a second metal salt and an accelerator selected from the group of anilines, amines, amides, pyridines, and combinations thereof. The catalyst system catalyzes a free-radical reaction of the urethane acrylate composition. The resin and catalyst systems may be used in a method of making a composite structure in a mold. The method includes applying a first layer and the urethane acrylate composition to the mold. The method further includes curing the structure in the mold and demolding the structure from the mold.

    • New, useful and surprisingly effective polymeric triphenylmethane colorant-containing compositions which exhibit very low color degradation within polyurethane foams. Generally during polyurethane foam production, certain amine-based hydroxyl-group containing catalysts deleteriously attack the nitrogen linking groups within triphenylmethane polymeric colorants. Such compositions require the presence of nominal yet effective amounts of organic cyclic ester materials. The ring systems of such materials appear to open during exposure to heat (during the foaming procedure) and release carboxylic acids into the foaming formulation. The tertiary amines become quenched by the carboxylic acids and thus do not exhibit degradation of the TPM-based chromophore. The resultant foams exhibit substantially uniform color throughout. The process and resultant foams are also contemplated within this invention.
    • 新的,有用的和惊人的有效的聚合三苯基甲烷着色剂组合物,其在聚氨酯泡沫内表现出非常低的颜色降解。 通常在聚氨酯泡沫生产过程中,某些含胺基羟基的催化剂会有害地侵蚀三苯甲烷聚合物着色剂中的氮连接基团。 这样的组合物需要有名义上有效量的有机环状酯材料。 这种材料的环系统在暴露于热(在发泡过程中)期间似乎打开并将羧酸释放到发泡制剂中。 叔胺被羧酸猝灭,因此不会表现出基于TPM的发色团的降解。 所得泡沫整体表现出基本均匀的颜色。 本发明也考虑了该方法和所得泡沫。
