  • Patent number: 7175959
    Abstract: A toner including core particles containing at least a resin and a colorant and coated with a resin coating layer is provided. The core particles are formed by flocculating and fusion-bonding at least resin microparticles and colorant microparticles dispersed in fluid dispersion, while two or more coating layers are formed over the core particles. A wax is added to at least one of the coating layer(s) but for the outermost coating layer, and the core particles. A ratio d/r between an average thickness d of the overall coating layers and a volume average particle size r of the core particles is adjusted to 0.01 to 0.6.

  • Patent number: 5230891
    Abstract: The invention provides a modified protease such that a protease is coupled to a polysaccharide via a triazine ring. This modified protease is considerably stable, safe and active as compared with the conventional modified proteases and immobilized proteases. Therefore, cosmetic products containing this modified protease are less liable to undergo aging, easier to use and improved in effect on the skin.
