Abstract

Disclosed are an anti-scattering film with excellent optical and scratch-resistant properties and a method for manufacturing the same. The anti-scattering film according to the present invention comprises: a transparent film; and a hard coating layer formed on the top of the transparent film, wherein the hard coating layer comprises 1-30 parts by weight of inorganic nanoparticles, 1-70 parts by weight of a UV-curable acrylate resin, 1-15 parts by weight of a photo-initiator, and 0.2-5 parts by weight of azo-based dyes, with respect to 100 parts by weight of solids.

First claim

1 . An anti-scattering film, comprising:
a transparent film, and a hard coating layer formed on an upper surface of the transparent film, wherein the hard coating layer comprises 1-30 parts by weight of inorganic nanoparticles, 1-70 parts by weight of a UV-curable acrylate resin, 1-15 parts by weight of a photo-initiator, and 0.2-5 parts by weight of azo-based dyes, with respect to 100 parts by weight of solids.

2 . The anti-scattering film according to claim 1 , wherein the hard coating layer has a pencil hardness of 2H to 9H.

3 . The anti-scattering film according to claim 1 , wherein the hard coating layer has a contact angle of 70° or less.

4 . The anti-scattering film according to claim 1 , wherein the hard coating layer has a transmittance of 90% to 100%.

5 . The anti-scattering film according to claim 1 , wherein the hard coating layer has a thickness of 1 μm to 10 μm.

6 . The anti-scattering film according to claim 1 , wherein the transparent film comprises at least one selected from polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyethersulfone (PES), polycarbonate (PC), polyethylene (PE), and poly propylene (PP).

7 . The anti-scattering film according to claim 1 , further comprising an adhesive layer formed on an opposite surface of the transparent film.

8 . The anti-scattering film according to claim 7 , wherein the adhesive layer comprises at least one selected from an acrylic adhesive, a silicone adhesive, and an acid-free type of hydroxyl containing adhesive.

9 . A method for manufacturing an anti-scattering film, comprising: applying, drying and curing a hard coating solution onto a surface of a transparent film to form a hard coating layer, wherein the hard coating layer comprises 1-30 parts by weight of inorganic nanoparticles, 1-70 parts by weight of a UV-curable acrylate resin, 1-15 parts by weight of a photo-initiator, and 0.2-5 parts by weight of azo-based dyes, with respect to 100 parts by weight of solids.

10 . The method according to claim 9 , wherein the hard coating solution is applied onto a surface of the transparent film by roll-to-roll process.

11 . The method according to claim 9 , further comprising forming an adhesive layer onto an opposite surface of the transparent film.
