LIGHT-DIFFUSING FLUORESCENT PARTICLE-CONTAINING MOLDED BODY

摘要

PROBLEM TO BE SOLVED: To provide a light-diffusing fluorescent particle-containing molded body which is excellent in light diffusion properties, moisture resistance and heat resistance and has less deterioration of total light transmittance and high transmission efficiency of diffusion light.

SOLUTION: There is provided a light-diffusing fluorescent particle-containing molded body obtained by blending a transparent base resin with light-diffusing fluorescent particle. The light-diffusing fluorescent particles are polymer particles derived from a polymerizable vinyl monomer containing a fluorescent dye having a refractive index difference from the transparent base resin of 0.01 to 0.10 and a value of diffused light transmittance represented by the expression: Diffused light transmittance (%)=Total light transmittance (%)×Haze×0.01 is 80% or more.
