A method and system for a multi-layer peelable nail cosmetic compositions are disclosed. The multi-layer system includes a water-washable, non-UV curable nail basecoat composition in a hand-held, non-pressurized container. The basecoat composition includes a hydrophilic poly(N-vinyl)lactam polymer, at least one alcohol, and at least one plasticizer. The multi-layer system also includes a colored non-UV curable nail colorcoat composition that includes a primary film former, a secondary film former, a plasticizer, and a colorant.

Methods and devices for producing artificial nails are disclosed, comprising: automatically recognizing user nail information by means of a 3D scanner (S100); recognizing a selected nail decoration design of a 2D or 3D form by means of a UV 3D printer (S200); a step in which the UV 3D printer, equipped with a device capable of adjusting a Z axis, forms a decoration layer corresponding to a curved surface of a user's nail shape with the nail decoration design recognized in step S200, on the basis of the user nail information recognized in step S100 (S300); a step in which the UV 3D printer forms an adhesive layer to be attached with the decoration layer produced in step S300; and a step of completely curing the decoration layer and the adhesive layer in a short time by subjecting same to heat treatment by using a UV lamp of the UV 3D printer, thereby printing an artificial nail in which the adhesive layer is coupled to the bottom of the decoration layer.

The present invention relates to effect pigments which are based on flake-form substrates having a circular form factor of 1.2-2 and are coated with at least one high-refractive-index layer, and to the use thereof, inter alia in paints, coatings, printing inks, plastics and in cosmetic formulations.
