The photo-hardening artificial nail composition that obtained hardening is completed is based on cross cut test method(s), forms 2mm × 2mm Grid, make adhesive tape attachment removed.The number for counting remaining grid after removing, to judge adhesiveness.
(state after being coated on nail 14 days)
Handle moccasin after, in the natural nail for using the degreasing of SOLMIX institute be coated with photo-hardening artificial nail composition, And irradiation makes its hardening in ultraviolet light 30 seconds using the UV lamp of the LED of 12W as light source.Thereafter, observation occurs to be used as artificial nails Beauty, notch, removing, the number of days passed through until any one of xanthochromia.
Table 1
The mixture of phosphate methacrylate is methacrylic acid propionic acid pentyl, bis- (methacrylic acids third Sour amyl) phosphate and three (methacrylic acid propionic acid amyl) phosphates mixture.
LUCIRIN TPO is 2,4,6- trimethylbenzene acyl group diphenyl phosphine oxides.
IRGACURE184 is 1- hydroxy-cyclohexyl-phenyl -one.
According to the above embodiments and comparative example as a result, the light of the Examples 1 to 9 through cooperating phosphorus compound of the invention Hardenability artificial nail composition, after being coated on scleronychia, the adhesiveness by nail known to cross cut method is good, not Peeling-off situation.In addition, even if the photo-hardening people hardened also does not occur after being coated on scleronychia 14 days The case where work nail composition tilts from nail or generates notch.
From this result, photo-hardening artificial nail composition of the invention will not it is peeling-off in nail surface but Bonding, and after coating hardening 14 days, still bonded well without change.
In contrast, according to the photo-hardening artificial nail composition of the comparative example of unmated phosphorus compound of the invention, By by be just coated with the cross cut method after hardening confirm nail adhesiveness experiment it is found that peeling-off situation is more, this Outside, especially in comparative example 3, although being coated with known to the test of cross cut method relative to nail surface good bonding Hardening 3 days after but occur from nail surface remove, and can not prolonged adhesion in nail surface.
By such result it is found that in photo-hardening artificial nail composition, closed by the phosphatization in the cooperation present invention Object forms the effective envelope of photo-hardening artificial nail composition during can growing, certainly in nail surface.
In addition, according to the present invention, due to not using organic solvent, and will not make to harden because of oxygen interrupted.Therefore Compared with free-radical polymerised photo-hardening artificial nail composition, unhardened component residue is not had, and it can be made hard Change.
In turn, due to not needing to polish to the nail surface of user itself to make to form bumps The nail of user itself becomes broken.
In addition, after coating, can prevent as stink caused by remaining organic solvent or unhardened ingredient etc. production It is raw, and organic solvent or unhardened ingredient will not be impregnated into vivo from nail, thus will not irritating skin the case where.
