Abstract

Artificial hair made of fibers containing poly acid derivatives. (Formula)Amino that is insoluble in water and alcohol and is represented by the following general formula (1)-(4) (chemical formula), where R in each formula (1)-(4) above is Ra, Rb and Rc1 are represented by the following formulas (5), (6) or (7), respectively (chemical formula), or are made from copolymer-containing polyaminoacurethane fibers. of the amino acid N-carboxyanhydride and polyurethane This copolymer was amided with organic diamines and organic amines with amino and mercapto groups or disulfide groups. and forming it in the form of fibers This artificial hair is dyed. The ability to maintain a natural, soft feel and yet flexible. have touch and excellent brushing, as well as a natural color, gloss and texture that is very similar to natural protein fibers.
