TRANSPARENT SCREEN HAVING LIGHT-SCATTERING FILM, AND COATING LIQUID FOR FORMING LIGHT-SCATTERING FILM

摘要

The present invention provides a light-scattering film that has "transparency" and "light scattering" properties while using inorganic oxide polymers as a medium. This light-scattering film contains high-refractivity grains of diamond, etc., inorganic oxide polymers having a higher refractive index than the refractive index of the high-refractivity grains, and a surface-modifying polymer for dispersing the high-refractivity grains in the inorganic oxide polymers. In the light-scattering film, taking the total value (A+B+C) of the mass (A) of the high-refractivity grains, the mass (B) of the surface-modifying polymer, and the mass (C) of the inorganic oxide polymer medium to be 100% by mass, the A/(A+B+C) is 1.0 to 10.0% by mass and B/A is 4.0 or greater. A transparent screen having a light-scattering film provided to a transparent base material is also disclosed. Furthermore, a method for manufacturing a light-scattering film and a transparent screen is also disclosed.
