摘要： A conducting composition of the present invention includes a cellulose nanofiber and a fine particle. The conducting composition includes (A) a cellulose nanofiber, and (B) at least one type of an inorganic powder selected from graphene, graphene oxide, and derivatives thereof. A method for producing the conducting composition includes preparing a dispersion by adding water or a mixed solvent of water and a hydrophilic solvent to (A) a cellulose nanofiber and (B) at least one type of an inorganic powder selected from graphene, graphene oxide, and derivatives thereof, and removing the water or the mixed solvent of water and a hydrophilic solvent from the dispersion. Accordingly, the present invention provides a conducting composition that utilizes a cellulose nanofiber and an inorganic powder having the conductivity at a nano-scale size, can improve the conductivity, and further can have properties such as anisotropy and transparency.

摘要： A phosphor-containing identification substance of the present invention includes a substrate and a phosphor-containing silicone thin layer. The whole or part of the surface of the substrate is covered with the phosphor-containing silicone thin layer. The phosphor has identification properties that the phosphor emits light when irradiated with ultraviolet rays or black light, and does not emit light when irradiated with visible rays. A method for producing the phosphor-containing identification substance of the present invention includes bringing a silicone composition for forming a phosphor-containing thin layer into contact with the substrate after or simultaneously with the molding of the substrate, followed by heating. This provides the phosphor-containing identification substance that can be applied to a silicone thin film, has excellent adhesive properties with the substrate, and maintains the inherent properties of the substrate without being impaired by marking, and the method for producing the same.
