[Technical Field]

The present invention also relates to the use of the compositions, multipart compositions comprising the compositions, and methods for applying the compositions to keratinous materials. [Background technology]

[0002] Traditional tattoos involve penetrating the dermis layer of the skin with pigment, and while the initial treatment cost is high, once applied, the tattoo is permanent and not easily removed.

[0003] In recent years, following traditional tattooing procedures, henna tattoos (a method of drawing on the body using ink), water transfer stickers (a form of applying transfer paper to the body using water), and other body painting methods using ink in various ways, such as stamping patterns, have been proposed.

[0004] Among temporary body painting methods, a method of printing onto the skin using a two-component skin printing ink is reported in KR101655978 B1 and KR20180057953 A. The two-component skin printing ink in these methods comprises an ink composition and an ink-immobilizing or fixing composition as a primer for the ink composition.

[0005] There is a need to improve the stability of primer compositions for the application of ink compositions to keratinous materials. [Prior art documents] [Patent Documents]
