REMOVABLE PROTECTIVE TOPCOAT FOR ARTIFICIAL NAIL COATINGS AND RELATED METHODS Russian patent published in 2016 - IPC C08L33/00 C09D4/06 A61Q3/02 A45D31/00 

FIELD: chemistry.

SUBSTANCE: invention relates to polymerisable compositions for nail coating. Described is a multilayer nail coating system, comprising a nail surface adhesive layer of a basic polymer coating, an intermediate decorative layer and a topcoat layer. The topcoat layer is provided by a liquid composition capable of polymerisation when exposed to actinic radiation. The composition includes hydroxypropyl methacrylate (HPMA), reactive urethane methacrylate, about 5 to about 90 wt % of a non-reactive, solvent-soluble polymer, such as cellulose acetate alkylate, and a non-reactive solvent selected from acetone, ethyl acetate, butyl acetate, isopropyl alcohol, ethanol, methyl ethyl ketone, toluene, hexane and mixtures thereof.

EFFECT: protective topcoat layer has scratch resistance; the system is easily removable from the nail surface in 20 minutes or less upon contact with an organic solvent.
