The present invention provides mixtures of compounds and compounds having the formula:
which are useful as functionalized photoinitiators and which may be used directly or after further functionalization in various photo-curable coating compositions, including varnishes, lacquers, printing inks and the like. The present invention also relates to a process to prepare the mixtures and the compounds. The present invention also provides radiation-curable surface coating compositions which include at least one of the compounds of the present invention as a photoinitiator. The compounds are especially suitable for radiation curable formulations which are intended for applications where low extracables or leachables are used such as printing inks for food packaging.
本发明提供了具有以下式子的化合物混合物:
本发明提供了可用作官能化光
引发剂的混合物和化合物,它们可直接或经进一步官能化后用于各种光固化涂料组合物,包括清漆、油漆、印刷油墨等。本发明还涉及一种制备混合物和化合物的工艺。本发明还提供了包括至少一种本发明化合物作为光
引发剂的辐射固化表面涂层组合物。本发明化合物尤其适用于辐射固化制剂,这些制剂可用于使用低可外加物或低浸出物的应用领域,如食品包装印刷油墨。
