Abstract

An antiglare film with various inner and outer haze includes a transparent substrate, and an antiglare coating layer formed by coating an antiglare coating solution on the transparent substrate. The antiglare coating solution further includes a resin, resin-philic light-scattering particles and resin-phobic light-scattering particles. The resin-philic light-scattering particles and the resin-phobic light-scattering particles respectively have different functional groups on the surfaces thereof. The resin-philic light-scattering particles do not repel the resin and thus are distributed inside the antiglare coating layer. The resin-phobic light-scattering particles repel the resin and thus are distributed on the surface of the antiglare coating layer, so that the inner and outer haze of an antiglare film can be effectively controlled via adjusting the proportion of the resin-phobic to resin-philic light-scattering particles.

Claims (9)

1. An antiglare film with resin-philic light-scattering particles and resin-phobic light-scattering particles, comprising:

a transparent substrate; and

an antiglare coating layer formed via coating an antiglare coating solution on the transparent substrate,

wherein the antiglare coating solution further comprises a resin, a solvent, an initiator, resin-philic light-scattering particles and resin-phobic light-scattering particles, wherein each resin-phobic light-scattering particle includes the resin-philic light-scattering particle and a segregating layer covered on a surface of the resin-philic light-scattering particle, and wherein the resin-philic light-scattering particles are distributed inside the antiglare coating layer, and the resin-phobic light-scattering particles are distributed on a surface of the antiglare coating layer.

2. The antiglare film with various inner and outer haze according to claim 1 , wherein the resin-philic light-scattering particles and the resin-phobic light-scattering particles respectively have different functional groups on surfaces thereof.

3. The antiglare film with various inner and outer haze according to claim 1 , wherein the resin-phobic light-scattering particles is formed via modifying a surface of the resin-philic light-scattering particles.

4. The antiglare film with various inner and outer haze according to claim 1 , wherein the resin is an ultraviolet-curable resin or a thermal-curable resin.

5. The antiglare film with various inner and outer haze according to claim 1 , wherein each of the resin-philic light-scattering particle and the resin-phobic light-scattering particle is an organic particle or an inorganic particle, and wherein the inorganic particle is made of a material selected from a group consisting of silicon oxide, aluminum oxide, antimony-doped tin oxide, tin oxide, zinc antimonite, antimony pentoxide, indium tin oxide, aluminum-doped zinc oxide, and zinc antimonate, and wherein the organic particle is made of a material selected from a group consisting of PMMA (poly(methyl methacrylate)), polystyrene, and benzoguanamine.

6. The antiglare film with various inner and outer haze according to claim 1 , wherein the resin-philic light-scattering particles and the resin-phobic light-scattering particles have a diameter of between 0.5 and 10 μm.
