Abstract
An artificial human nail structure is described which is formed of polymerized alkyl methacrylate and hydroxyalkyl methacrylate in a weight ratio in the range of 1-50 parts of alkyl methacrylate per part of hydroxyethyl methacrylate, preferably a ratio of 2-20:1, and more preferably of 3-10:1, and wherein said alkyl moiety of either is any C.sub.1 -C.sub.4 alkyl, preferably ethyl. The artificial nail coating can be easily applied, polymerizes readily and rapidly without catastrophic crystallization and produces a transparent and easily shaped artificial nail structure. Also disclosed is an artificial human nail surface precursor having as its principal component a mixture of alkyl methacrylate and hydroxyalkyl methacrylate in the above mentioned weight ratio. Nail materials formed exhibit high impact resistance, improved stiffness, good flexural strength, resistance to cracking and breaking, good workability, improved compatibility with the natural nail surface, good transparency, clarity and moldability, may need not primer, has increased adhesion, better stability, and have no tendency toward catastrophic crystallization.
