Nail sticker, composition for nail sticker and method for preparing composition

Abstract

A nail sticker, a composition for the nail sticker and a method for preparing the composition are disclosed. Raw materials of the composition include a sizing material, which is made of the following raw materials in parts by weight: 45-85 parts of a UV thermosetting resin, 2-9 parts of a photoinitiator, 1.5-2 parts of a curing agent, 0.1-1 part of a thermal promoter, and 0.1-1 part of a leveling agent. The synchronization of the release of essential oil molecules with light/thermal curing promotes the essential oil molecules to be diffused to the interior of the sizing material more uniformly in a wider range, and during the curing and film forming of the nail sticker, an aroma spreads as tantalizing as that of baked food.
