Definitions

• the present invention relates to nail compositions comprising at least one color coat and at least one primer, wherein the primer comprises at least one solvent and at least one adhesive compound.
• the primer preferably further comprises at least one plasticizer. Owing to the primer, such nail compositions can be easily removed with less damage to nails and with more time efficiency.
• UV gel compositions typically consist of a layer of basecoat for adhesion on the nails, two color coats to enhance the color, and one top coat for shine. Each coating needs to be cured with a UV Lamp or UV LED.
• a UV gel composition set is a system that contains base coat, color coat and top coat layers. The UV gel composition set's adhesion on the nail and the cohesion among the layers is so strong that it is difficult to remove such compositions from nails. To remove such UV gel products from nails, it is usually required to soak nails with harsh solvent such as acetone for 10 minutes or more to effect removal. Frequent and/or prolonged use of such solvents in this manner can damage nails such as, for example, by making them dry and brittle.
• US201 1274633A relate to the use of a non-reactive, solvent-dissolvable polymer such as cellulose acetate butyrate, cellulose acetate propionate, and mixtures to enhance removal properties. Adding such non-reactive, solvent-dissolvable compounds improves the soaking of the coatings by solvent and hence can speed up the removal process. The speed of removal depends on the type and the quantity of additives introduced in the composition. However, the removal process remains less than ideal.
• UV gel compositions which are safe and adhere well to nails, yet which can be easily removed with less damage to nails and with more time efficiency.

• Film former or "film forming agent” as used herein means a polymer or resin that leaves a film on the substrate to which it is applied, for example, after a solvent accompanying the film former has evaporated, absorbed into and/or dissipated on the substrate.
• Makeup Result refers to compositions where color remains the same or substantially the same as at the time of application, as viewed by the naked eye, after an extended period of time.
• “Makeup Result” may be evaluated by evaluating long wear properties by any method known in the art for evaluating such properties. For example, long wear may be evaluated by a test involving the application of a composition to nails and evaluating the color of the composition after an extended period of time. For example, the color of a composition may be evaluated immediately following application to nails and these
• characteristics may then be re-evaluated and compared after a certain amount of time. Further, these characteristics may be evaluated with respect to other compositions, such as commercially available compositions.
• Adhesion refers to chemical or physical bonding between a coating and a substrate. Good adhesion between nail polish and nail surface should translate to good wear properties on consumers. Adhesion properties can be quantified by in-vitro method such as a cross-cut adhesion test. In the test, a lattice pattern is cut into the coating and penetrates through to the substrate. A pressure sensitive tape is applied to the sample and then pulled off. The adhesion property can be quantified by the area of the coating remaining after peeling. For example, if the whole film remains after peeling, it indicates excellent adhesion. If most of the film gets peeled off, it indicates poor adhesion.
