PROBLEM TO BE SOLVED: To provide coating compositions that include an alkoxide of the general formula RM(OR'), where R is an organic group, M is silicon, aluminum, titanium, and/or zirconium, each R' is independently an alkyl group, z is the valence of M, and x is a number less than z and may be zero.SOLUTION: The coating composition is cationically curable. Also disclosed are articles at least partially coated with a hard coat deposited from such a coating composition, methods for depositing a hard coat on at least a portion of a plastic substrate, and methods for improving the adhesion and abrasion resistance of a substrate.SELECTED DRAWING: None 【課題】一般式ＲｘＭ（ＯＲ'）ｚ−ｘ（式中、Ｒは有機基であり、Ｍはケイ素、アルミニウム、チタン、および／またはジルコニウムであり、各Ｒ'は、独立に、アルキル基であり、ｚはＭの原子価であり、ｘはｚ未満の数値であり、かつゼロとすることができる）のアルコキシドを含む、コーティング組成物を提供すること。【解決手段】このコーティング組成物は、カチオン硬化性である。そのようなコーティング組成物から堆積されるハードコートで少なくとも部分的にコーティングされた物品、プラスチック基材の少なくとも一部の上にハードコートを堆積するための方法、および基材の接着性および耐摩耗性を改善するための方法も開示されている。【選択図】なし
