Description
Technical field
The present invention relates to a kind of polymerisable compound and a kind of blooming that comprises by the formed coating of described polymerisable compound, this blooming can be used in the backlight module (BLU) of indicating meter as brightness enhancement film.
Background technology
Liquid-crystal display (Liquid Crystal Display, LCD), have light, thin, short, little, low thermal losses, low power consumption and advantage such as radiationless injury almost, replaced conventional cathode ray tube (Cathode Ray Tube at present, CRT) indicating meter becomes the market mainstream.
In backlight module, utilize blooming miscellaneous to improve panel briliancy (luminance), become most economical and easy product development scheme, mode not only must not changed any component design according to this, must not consume additional energy source yet, and can improve LCD panel briliancy and make light source do the performance of full blast.
Brightness enhancement film is called for short BEF (Brightness Enhancement Film) usually or claims condensing film, and it can be coated with special acryl resin coating by on polyester substrate, utilizes high-energy ultraviolet ray (UV) that it is hardened into prism microstructure and makes.The major function of brightness enhancement film is by the effect of refraction with inner full-reflection, will collect and be concentrated to positive visual angle (On-Axis) direction of degree approximately ± 35 by the ghost line that light guiding plate (Light Guide) is issued to from all directions, to improve the briliancy of LCD.
General brightness enhancement film commonly used is to utilize the ultraviolet curing polymeric composition, generally speaking selects the polymeric composition coating of high index for use, and the brightening effect of brightness enhancement film is good more.
At present known to adding halogen-containing monomer or oligopolymer in polymerisable compound, obtaining to have the polymeric composition coating of high index, yet the existence of halogen can cause environmental pollution.
In addition, can utilize 4,4 '-two (methacrylic vinegar sulfenyl) diphenyl sulfide (4,4 '-bis (methacroylthio) diphenyl sulfide, MPSMA) monomer, structural formula is as follows:
For example United States Patent (USP) discloses this monomer synthetic method for No. 5183917 and contains its composition, and the MPSMA monomer is a crystalline solid, has high refractive index, but shortcoming is to be insoluble in other monomer, is unfavorable for coating; No. 5969867 announcement of United States Patent (USP) utilizes two (methacrylic vinegar oxygen ethoxyl phenenyls), third hydrocarbon (bis (methacryloxyethoxyphenyl) propane) monomer to dissolve MPSMA, but the specific refractory power of two (methacrylic vinegar oxygen ethoxyl phenenyls), third hydrocarbon monomer is low, so need to use a large amount of MPSMA monomers, could promote the specific refractory power of polymeric composition; In addition, No. the 6541591st, United States Patent (USP), No. the 6953623rd, United States Patent (USP) etc. all utilizes the MPSMA monomer improving specific refractory power, but the MPSMA monomer costs an arm and a leg, and is unfavorable in industrial a large amount of uses.
Moreover, utilize interpolation nano inorganic particulate to improve specific refractory power, for example No. the 7282272nd, United States Patent (USP) discloses a kind of brightness enhancement film that improves its specific refractory power via adding the nano inorganic particulate, but the shortcoming of this method is a nanoparticle to be difficult for being dispersed in and to influence operation ease in the coating.
This shows that above-mentioned existing brightness enhancement film obviously still has inconvenience and defective, and demands urgently further being improved in structure and use.In order to solve the problem of above-mentioned existence, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but do not see always that for a long time suitable design finished by development, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of polymerisable compound and comprise the blooming of this polymerisable compound, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
In sum, the invention provides a kind of do not have above-mentioned shortcoming and easy to operate and comparatively economic high refractive index polymer coating, further improved the luminance gain value of brightness enhancement film.
