Embodiment 1

[0054] Example 1. Preparation of photochromic nail polish without base color

[0055] 1. Preparation of photochromic materials and their solutions

[0056] The structural formula of the photochromic material used in this embodiment is as follows:

[0057]

[0058] In formula I-a, Represents zinc ion (Zn 2+ ).

[0059] The preparation method of the photochromic material is the same as the preparation method of the photochromic material shown in formula I (the synthetic route is as figure 2 Shown), R in fluoran compound 1, compound 2, salicylaldehyde derivative 3 and fluoran hydrazide-salicylic aldehyde hydrazone 4 1 , R 2 , R 3 , R 4 Same as formula I-a. The concentration of the resulting photochromic material solution is 10×10 -3 mol / L, the solvent is ethyl acetate.

[0060] The structure verification data is as follows:

[0061] 1 H-NMR(CDCl 3 ),δ(ppm): 1.11(m,18H,NCH 2 CH 3 ), 3.27(m,12H,NCH 2 CH 3 ), 6.09(m, 2H, Phen-H), 6.23(dd, 2H, Xanthene-H), 6.47(d, 2H, Xanthene-H), 6.49(d, 2H...

Embodiment 2

[0068] Example 2. Preparation of photochromic nail polishes with multiple background colors

[0069] 1. Preparation of photochromic materials and their solutions

[0070] The photochromic material used in this example is the same as that in example 1.

[0071] The preparation method of the photochromic material is the same as in Example 1.

[0072] 2. Preparation of photochromic nail polish with a variety of background colors

[0073] Weigh 9.0 mL of commercially available colorless ordinary nail polish, add 0.5 mL of commercially available pigment and 1.0 mL of the above-mentioned self-made photochromic liquid, stir to dissolve, and obtain photochromic nail polishes with various background colors.

[0074] 3. Color changing effect

[0075] Such as Figure 4 As shown, Figure 4 A is a photochromic nail polish with a variety of background colors (from left to right: lake blue, dark blue, green, yellow, colorless, white, orange, and light pink); Figure 4 B is the nail polish with different...

Embodiment 4

[0076] Example 4. Preparation of photochromic nail polish without background color (composed of 70% nail polish and 30% photochromic material solution)

[0077] 1. Preparation of photochromic materials and their solutions

[0078] The photochromic material used in this example is the same as that in example 1.

[0079] The preparation method of the photochromic material is the same as in Example 1.

[0080] 2. Preparation of photochromic nail polish

[0081] Take 3.5 mL of commercially available colorless ordinary nail polish, add 1.5 mL of the above photochromic solution, and stir to dissolve to obtain photochromic nail polish.

[0082] 3. Color changing effect

[0083] Such as Figure 5 As shown, the photochromic nail polish prepared in this example changes from transparent to red after being irradiated with sunlight. After the light disappears, the color returns to transparency.

Abstract

The invention discloses a photochromic nail polish and a preparation method thereof. The photochromic nail polish is composed of 70-98% of a nail polish and 2-30% of a photochromic material solution in volume percentage, wherein the photochromic material solution is composed of a complex compound shown in the formula I and an organic solvent; in the photochromic material solution, the molar concentration of the complex compound shown in the formula I is (1-40)*10<-3>mol / L; and in the formula I, the black ball represents metal ions, and R1, R2, R3 and R4 are respectively selected from any one of alkyl, aryl and amido independently. The photochromic nail polish disclosed by the invention has excellent photochromic properties: obvious color change before and after illumination, sensitive response to light and reversible color change processes; the photochromic nail polish has shiny gloss and can form a good polished surface on nails, thereby overcoming the defects of other photochromic nail polishes that the nail polishes are gloomy and varnishes need to be smeared additionally; and the preparation method is very simple, the cost of the raw materials is very cheap, the supply of the raw materials is stable, and the mass production is very easy.

Description

Technical field [0001] The invention belongs to a nail polish and a preparation method thereof, in particular to a photochromic nail polish and a preparation method thereof. Background technique [0002] Nail polish is a common cosmetic that is widely used on nails or toenails. Its color is rich and gorgeous, and it has both beautiful and protective effects. The common nail polish has only one color, does not have the color changing function, and has a single color tone. Photochromic nail polish refers to a nail polish that can change color under light, and its reversible photochromic effect can bring great aesthetic and visual enjoyment to users. At present, there are several photochromic nail polishes on the market, such as the photochromic nail polishes produced by Delsol in the United States, Cosmay in Canada, and Sweet Color in France. However, the photochromic nail polishes of these manufacturers have a matte effect. After being applied to the nails, they are dull and dul...
