Abstract
The present invention describes compositions that are useful for making artificial fingernails, in particular such compositions that are odorless, non-toxic, self-curing, and demonstrate good working properties as described above. Compositions in accordance with this invention consist of two parts: PA1 (a) an odorless, non-toxic liquid binder comprising one or more methacrylate monomer(s) of the following formula: EQU R--O--CH.sub.2 CH.sub.2 --O--CH.sub.2 CH.sub.2 --O--CO--C(CH.sub.3).dbd.CH.sub.2 PA1 where R is CH.sub.3 (CH.sub.2).sub.n and n=0-3 together with one or more di-,tri-, or multi-functional methacrylates, and a teriary-amine type accelerator; and PA1 (b) a polymeric powder containing a finely divided methacrylate polymer or copolymer, and a peroxide polymerization initiator. Upon mixing the above two components and subsequently shaping the resulting dough-like mass on a human fingernail, a hard, fused polymer is obtained in the shape of an artificial fingernail in from about 60 seconds to about 180 seconds at ambient temperatures.
