Problems solved by technology

[0004] Manicure materials using this lacquer-based coating material have been widely spread, but have the following problems: they have poor adhesion to natural nails and may be peeled or removed in a short time after application
Although improvements in the use of ultraviolet rays harmful to the human body are recognized, improvements in hardening properties, yellowing, internal hardening, etc. of the composition are not considered

Abstract

An object of the present invention is to provide an artificial nail composition having improved curability. Another object of the present invention is to provide an artificial nail composition which causes less yellowing and has excellent internal curability. The artificial nail composition comprises: a component (a): a compound having at least one radical polymerizable unsaturated double bond in the molecule, and a component (b): a photopolymerization initiator selected from (i) an acylphosphine oxide-type photopolymerization initiator and (ii) a mixture of an acylphosphine oxide-type photopolymerization initiator and an alpha-hydroxyalkylphenone-type photopolymerization initiator, wherein the amount of the component (b) is 0.05 to 4.00 parts by weight with respect to 100 parts by weight of the component (a). It is preferred that the acylphosphine oxide-type photopolymerization initiator is monoacylphosphine oxide and / or bisacylphosphine oxide, and the alpha-hydroxyalkylphenone type polymerization initiator is 1-hydroxy-cyclohexyl-phenyl-ketone or 2-hydroxy-2-methyl-1-phenyl-propan-1-ketone.

Description

technical field [0001] The present invention relates to artificial nail compositions having improved hardening properties. Background technique [0002] Nail art means the makeup or decoration of fingernails and toenails. A nail art store is referred to as a nail salon, and a nail artisan is referred to as a nail technician. A variety of nail art products are commercially available, and there are many women who perform nail art with the skills of a professional. [0003] In the 19th century, paint coating materials for motor vehicles were invented in the United States, and manicures currently used were developed by employing this technology. [0004] A manicure material using this lacquer-based coating material has been widely spread, but has problems in that it has poor adhesion to natural nails and may be peeled or removed within a short time after coating. Therefore, artificial nail materials using dental resins polymerizable at ordinary temperatures have been develope...
