摘要:
A polymer composition of excellent compatibility comprises a block copolymer containing a polyvinyl alcohol polymer unit as one constituent and a polymer unit having an ionic group as another constituent, and a protein. It is suitable, especially when the protein is gelatin, for making a photographic emulsion, microcapsules, a photosensitive material, etc.
