preparation example Construction

[0095]

[0096] Compositions of the present disclosure can be prepared by using the components described above. The preparation apparatus and conditions are not particularly limited. For example, the composition can be prepared by making the acrylamide compound (A1), polyfunctional The polymer compound (A2), pigment, dispersant, etc. are subjected to dispersion treatment to prepare a pigment dispersion liquid, and the pigment dispersion liquid is further mixed with a polymerization initiator, a polymerization inhibitor, and a surfactant.

[0097]

[0098] The viscosity of the composition of the present disclosure is not particularly limited because it can be adjusted according to the purpose and application device. For example, if a spraying device that sprays the composition from a nozzle is used, its viscosity is preferably in the range of 3 mPa·s to 40 mPa·s, more preferably 5 mPa·s in the temperature range of 20°C to 65°C, preferably at 25°C. s to 15 mPa·s, and parti...

Embodiment 1

[0142]

[0143] N-methylglycine methyl ester hydrochloride (available from Sigma-Aldrich Japan, reagent) (0.30 mol), potassium carbonate (available from Kanto Chemical Co., Inc., reagent) (0.45 mol) and water (400 mL) was stirred and mixed at 0° C. to 10° C., and while maintaining this temperature, acrylic acid chloride (available from Wako Pure Chemical Industries, Ltd., reagent) (0.33 mol) was slowly added dropwise to the resultant . After completion of the dropwise addition, the resultant was extracted three times with ethyl acetate (available from Kanto Chemical Co., Inc., reagent) (400 mL), and the resultant was washed once with water (400 mL) together with the ethyl acetate layer. Ethyl acetate was evaporated at 40° C. under reduced pressure to obtain the target N-acryloyl-N-methylglycine methyl ester (A1-1) (0.20 mol) in the form of an almost colorless transparent liquid. The purity was 98.3% by mass.

[0144] N-acryloyl-N-methylglycine methyl ester (A1-1) has a mol...

Embodiment 2

[0146]

[0147] The target N-acryloyl-N-isopropylglycine isopropyl ester (A1-2) (0.22 mol) was obtained as an almost colorless transparent liquid in the same manner as in Synthesis Example 1 except that it was different from Synthesis Example 1. Replace N-methylglycine methyl ester hydrochloride with N-isopropylglycine isopropyl ester hydrochloride (available from Tokyo Chemical Industry Co., Ltd., reagent). The purity was 98.5% by mass.

[0148] The molecular weight of N-acryloyl-N-isopropylglycine isopropyl ester (A1-2) was 213.2.

Abstract

Provided is a composition including an acrylamide compound (A1) having a molecular weight of 150 or greater but 250 or less; and a multifunctional polymerizable compound (A2), wherein the content of the multifunctional polymerizable compound (A2) is 15% by mass or greater but 35% by mass or less.

Description

technical field [0001] The present disclosure relates to a composition, an artificial nail composition, a nail decoration material, an artificial nail, a storage container, an image forming apparatus, and an image forming method. Background technique [0002] Nail art (nail art, Nail art) using gel nail materials needs to be tightly bonded to the nails to prevent easy peeling in daily life. On the other hand, when removing nail art, a swab or cotton impregnated with a solution called nail remover (which contains an organic solvent such as acetone as a main component) is usually left on the nail art so that it swells and Remove nail art. [0003] However, artificial nails excellent in tight adhesion to nails usually have a crosslinked structure and thus have excellent solvent resistance. Therefore, such artificial nails are difficult to remove by the above-mentioned method. Therefore, in order to remove the artificial nails, it is necessary to scrape off the artificial nai...
