Fibroin-coated pigment and processes for producing same

摘要

A fibroin-coated pigment and two processes for producing the same are disclosed. The fibroin-coated pigment comprises a carrier pigment in the form of finely divided particles whose surfaces are substantially coated with a film of regenerated fibroin and is characterized in that at least 50% by weight of the regenerated fibroin is constituted of hot-water-insoluble fibroin having the beta -configuration.
