  • Publication number: 20090317616
    Abstract: The present invention provides a melanin that is excellent in coloring a functional film, and in reproducibility and stability during storage, and a method for its production. Also, the invention provides a functional film containing a melanin and its method for production. Specifically, it provides a functional film containing a melanin of which the alteration is improved and which is excellent in the property for protecting eyes from ultraviolet rays, and in its method for production. The method for producing a melanin of the present invention, comprises, at least, under controlled conditions, a step for an oxidative reaction wherein a melanin precursor is continuously oxidized while the mole ratio of the melanin precursor relative to the oxidative agent is maintained at a constant ratio, and a step for precipitation wherein a melanin is precipitated by acidifying a reaction solution after the step for an oxidative reaction.
