The invention belongs to the field of new materials, and discloses a polymer hard coating and a preparation method thereof. Specifically, the present invention discloses a dispersion comprising at least 49% by weight of additive particles, polymerizable monomer, dispersant and solvent. After polymerization, the dispersion forms a hard coat having a haze of at most 0.5% and a light transmission of at least 90%. The present invention also discloses a hardcoat comprising at least 49% by weight of additive particles dispersed in a polymer. In addition, the present invention discloses a method of making a hard coat layer comprising forming a dispersion, applying the dispersion to at least one side of a substrate, and polymerizing the dispersion. The hard coat layer has a haze of at most 0.5% and a light transmittance of at least 90%. |
