Description
The application to be application number be 200910178872.6 name be called the divisional application of the application for a patent for invention of " polymerisable compound and comprise the blooming of this polymerisable compound ", the applying date of original application is on October 09th, 2009.
Technical field
The present invention relates to a kind of polymerisable compound and a kind of blooming comprising the coating formed by 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 (LiquidCrystalDisplay, LCD), there is light, thin, short, little, low thermal losses, low power consumption and the almost advantage such as radiationless injury, replaced conventional cathode ray tube (CathodeRayTube at present, CRT) indicating meter, becomes the market mainstream.
In backlight module, utilize blooming miscellaneous to improve panel briliancy (luminance), become most economical with easy Product development plan, mode not only must not change any component design according to this, also must not consume additional energy source, and LCD briliancy can be improved make light source do the performance of full blast.
Brightness enhancement film is called for short BEF(BrightnessEnhancementFilm usually) or claim condensing film, it is by polyester substrate, is coated with special acryl resin coating, utilizes high energy UV (UV) hardened into prism microstructure and obtain.The major function of brightness enhancement film is by the effect of refraction with inner full-reflection, will be collected and be concentrated to positive visual angle (On-Axis) direction of about ± 35 degree, to improve the briliancy of LCD by light guiding plate (LightGuide) ghost line be issued to from all directions.
General conventional brightness enhancement film utilizes ultraviolet curing polymeric composition, and generally speaking select the polymeric composition coating of high index, the brightening effect of brightness enhancement film is better.
Known to adding halogen-containing monomer or oligopolymer in polymerisable compound at present, to obtain the polymeric composition coating with high index, but the existence of halogen can cause environmental pollution.
In addition, two (methacrylic vinegar sulfenyl) diphenyl sulfide (4,4'-bis(methacroylthio) diphenylsulfide, the MPSMA of 4,4'-can be utilized) monomer, structural formula is as follows:
Such as No. 5183917th, United States Patent (USP) discloses this monomer synthesis and the composition containing it, and MPSMA monomer is crystalline solid, has high refractive index, but shortcoming is insoluble in other monomer, is unfavorable for coating; United States Patent (USP) No. 5969867 announcement utilizes two (methacrylic vinegar oxygen ethoxyl phenenyl) the third hydrocarbon (bis (methacryloxyethoxyphenyl) propane) monomer to dissolve MPSMA; but the specific refractory power of two (methacrylic vinegar oxygen ethoxyl phenenyl) third hydrocarbon monomer is low; therefore need to use a large amount of MPSMA monomer, the specific refractory power of polymeric composition could be promoted; In addition, No. 6541591st, United States Patent (USP), No. 6953623rd, United States Patent (USP) etc. utilize MPSMA monomer to improve specific refractory power, but MPSMA monomer is expensive, is unfavorable for industrially using in a large number.
Moreover, interpolation nano inorganic particulate is utilized to improve specific refractory power, such as No. 7282272nd, United States Patent (USP) discloses and a kind ofly improves the brightness enhancement film of its specific refractory power via adding nano inorganic particulate, but the shortcoming of this method is nanoparticle to be not easily dispersed in coating and to affect operation ease.
As can be seen here, above-mentioned existing brightness enhancement film with in use in structure, obviously still has inconvenience and defect, and is urgently further improved.In order to solve above-mentioned Problems existing, relevant manufactures there's no one who doesn't or isn't seeks solution painstakingly, but have no applicable design for a long time to be completed by development, and common product does not have appropriate structure to solve the problem, this is obviously the anxious problem for solving of relevant dealer always.Therefore how to found a kind of polymerisable compound and comprise the blooming of this polymerisable compound, belong to one of current important research and development problem in fact, also become the target that current industry pole need be improved.
In sum, the invention provides a kind of without above-mentioned shortcoming and easy to operate and comparatively economic high refractive index polymer coating, further increase the luminance gain value of brightness enhancement film.
