Blue light cut dye and blue light cut sheet comprising the dye
The present invention relates to a novel naphthalimide-based compound and a dye and a sheet for blue light blocking including the same. The present invention is excellent in a blue light blocking effect of a wavelength region of 400 to 450 nm. Since visible light in a region after 450 nm is hardly absorbed, a problem that the sheet is excessively yellowish does not occur. Also, since solubility in an organic solvent or a monomer is excellent, efficiency of a manufacturing process is high because a possibility of aggregation or precipitation of the dye in a molding process is low. The naphthalimide-based compound is represented by chemical formula 2.COPYRIGHT KIPO 2018
