Problems solved by technology

[0006] It is known that the addition of halogens can obtain polymer coatings with higher refractive index, however, the presence of halogens will cause environmental pollution
[0007] U.S. Patent No. 6,541,591 discloses a high refractive index polymerizable composition by adding 4,4'-bis(methacrylthio)diphenyl sulfide (4,4'-bis(methacroyl thio)diphenyl sulfide) Monomer to increase the refractive index, but the disadvantage is that the price of this monomer is too expensive

Embodiment Construction

[0073] The materials used in the following examples of the invention are:

[0074] (a): Compound of formula (I) (produced by Xinzhongcun Company, A-BPEF)

[0075] (b): Photoinitiator (produced by Ciba,

[0076] (c): crosslinking agent (produced by Changxing Company, 624-

[0077] (d): Formula (II) monomer (produced by Xinzhongcun Company, A-LEN10)

[0078] (d-1): acrylate monomer (produced by Changxing Company,

[0079] Prepare raw materials according to the first embodiment in table 1: component (a) 2.5g, component (b) 3g, component (c) 30g, component (d) 7.5g. The above raw materials were mixed, then placed at a temperature of 50°C and stirred at a speed of 1000 rpm to form a colloidal polymerizable composition.

[0080] The above prepared colloidal polymerizable composition is coated on a polyethylene phthalate (PET) substrate (model produced by TORAY Company), a coating is formed on the surface of the substrate, and then a prism pattern is formed on the coating...

Abstract

The present invention relates to a polymerizable composite, comprising (a) at least one compound shown in formula (I), wherein X1 and X2 are respectively H or C1-C4 alkyl. Y1, Y2, Y3 and Y4 are respectively H, C1-C4 alkyl or OH; and a and b are respectively an integer from 0 to 5 and (b) a photoinitiator. The weight percentage of the compound represented by formula (I) is at least 1% of the polymerizable composite. The present invention also relates to an optical film containing the coating formed by the polymerizable composite. The optical film can be used as a brightness enhancement film in the backlight module of a display.

Description

technical field [0001] The present invention relates to a polymerizable composition and its use in the preparation of optical films. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has the advantages of thinness, shortness, low heat generation, low power consumption, and almost no radiation, etc., and has gradually replaced traditional cathode ray tube (CathodeRay Tube, CRT) display. [0003] At present, using various optical films in the backlight module to increase panel brightness has become the most economical and convenient product development solution. In this way, not only does not need to change any component design, but also does not need to consume additional energy , and can improve the brightness of the LCD panel to make the most efficient use of the light source. [0004] The brightness enhancement film is usually referred to as BEF (Brightness Enhancement Film) or light-concentrating film. It is coated with a special acrylic ...
