TECHNICAL FIELD
2The present invention relates generally to coating compositions and particularly nail, but not limited to polymerizable compositions and adhesion promoter basecoat polymerized ones.
BACKGROUND
4The information below will not be accepted as prior to the invention of the art, but is solely to promote understanding.
5Compositions for artificial nails of fingers and toes in the form of coatings and means for improvement nails are well known and have become the main line of products for appearance and cosmetics industries. The appearance of someone's fingernails (and in most cases also toenails) has become important for many people looking for the latest fashions, or those who wish to correct physical defects of natural nails. Commercially available formulations of artificial nails are used to improve the appearance of the nails, as well as to enhance the physical properties of the nail, including the strengthening of brittle nail plate.
6Traditional nail can be classified into two categories: Nail polishes; also known as paints, coatings or glossy enamel and artificial nails; also known as acrylic polymers or gels. Nail polishes typically include various solid components are dissolved and / or suspended in non-reactive solvents. After application and drying of the solid components remain on the surface of the nail as a colorless, transparent or colored film. Typically, the means for polishing nails torn off easily and are easily removed with a solvent, usually within one minute, and if not removed, as described, are a rip off or go with the natural nail in one to five days.
7Traditional artificial fingernails are made of chemically reactive monomers and / or oligomers in combination with the reactive or non-reactive polymers to form systems that are usually 100% solids, and non-reactive solvents are not required. After pre-mixing and subsequent application to the nail plate and the application and effects of UV radiation causes a chemical reaction leading to the formation of stable, high-crosslinked thermoset coating nails, which are difficult to remove. Artificial nails may have greatly enhanced adhesion strength as well as resistance to scratch and solvent compared to nail polishes. However, because of the characteristic properties of such thermosetting materials are much more difficult to remove if the user wants it. Removal typically requires exposure to the non-reactive solvent for 30-90 minutes (for acrylics and currently available "macerated gels", it may take more than 90 minutes, if not removed traditional UV nail gels with a solvent ) and, as a rule, it can also be a significant abrasion or scraping of the surface of a wooden or metal fittings in order to facilitate the removal process.
8There remains a need for a cosmetic product which has improved adhesion and durability of thermosetting materials, also still has easy removal, which is more similar to means for removing nail polish.
9The present invention forms part of the nail, comprising a reactive adhesive layer base coat (the present invention, the application number 12/555571, filed September 8, 2009, currently pending), the average and reactive decorative color layer (application number 12/573633, filed Oct. 5, 2009, now pending) and a protective top layer, and reactive (application number 12/573640, filed October 5, 2009, currently pending).

32The solvent was slowly percolates through the outer surface and edges of a thermosetting material, and ultimately the coating swells. Eventually swelling weakens the whole matrix structure and destroys the adhesion to the nail surface. Even with poorly attached nail may need to increase the abrasion of the penetration of the solvent and removal rate. However, the low rate at which the solvent diffuses through thermosetting material that limits the speed of the swelling and subsequent removal.
33The present invention provides a 3-D lattice with a thermosetting interpenetrating network of voids remaining after removal of the solvent during curing, and the domains in an organic solvent soluble polymer. When the coating is exposed to organic solvents, the solvents penetrate into the material through the interstices remaining in the curing process with an ester of cellulose or other non-reactive organic solvent-soluble polymer which is dissolved a solvent, leaving afterwards voids which allow a better and fuller penetration into volume of material down to the interface polymer / fingernail. The result is the number of solvent accessible holes for the passage of fully penetrating the thermosetting material. Under these conditions, the solvent may destroy the internal space of a thermosetting resin, are no longer limited to a low speed of diffusion.
34The present invention provides a base coat as a middle layer between the nail and the ceiling surface.
