Description
The present invention relates to a kind of antireflection filter that is used on the display, this filter has good stain resistance, marresistance and anti-processability.This filter can also be used in the front surface of CRT.
When an object sees through a kind of transparent material when observed, can produce tedious strong reflection light or reflected image clearly.The reflected image that is called ghost image (ghost) or flare that for example appears on the eyeglass makes our eyes very uncomfortable.The reverberation of glass surface also can cause such problem, promptly because catoptrical existence thickens the reflection on the sight glass.
By vacuum moulding machine or similar approach a kind of material different with substrate reflectivity covered and to prevent reflection in the substrate.In said method, for obtaining best anti-reflection effect, the thickness of selecting to cover suprabasil material is considered to crucial.For example in individual layer, when the blooming of material that is lower than the refractive index of substrate when refractive index is selected as 1/4th or odd-multiple of target light source wavelength, can obtain minimum reflectance, i.e. maximum transmission.
Here used blooming one speech is meant the refractive index of filmogen and the product that described thickness multiplies each other and obtains.Also can form the multilayer anti-reflection layer, this proposed the method (referring to " optical technology communication ", the 9th the 8th phase of volume the 17th page (1977)) of several selection thickness.On the other hand, the clear 58-46301 of Japanese Patent Application Publication JP, the clear 59-49501 of JP, the clear 59-50401 of JP have described the method that forms multi anti reflection coating, and by using a kind of fluid composition, the blooming that obtains can satisfy above-mentioned situation.In recent years, advantage such as weighing fail safe by utilizing them and be easy to processing, be designed and put in the commercial Application with the antireflection optical articles of glass as substrate, all contain a kind of film in the structure of many this optical articles, the outermost layer of this film is a silicon dioxide.
Mainly form with the selected filmogen of antireflection film that sedimentation forms by inorganic oxide or inorganic halides.In the time of on being used in substrate of glass, antireflection film contains a kind of like this inorganic substances, and it has very high case hardness in fact, but also is accompanied by such problem simultaneously, promptly can be known and see, can not easily remove by the stain of hand, fingerprint, lotion or hair spray contamination.Also having a problem is that film surface sliding is poor, makes vestige become big.Simultaneously the other problem of Chu Xianing be with water be subjected to moist very greatly will extend thereon so that raindrop or water splash on the film, make that for example being reflected in object on the eyeglass appears to large-area distortion has taken place.
The clear 58-46301 of Japanese Patent Application Publication JP, the clear 59-49501 of JP, the clear 59-50401 of JP has described a kind of antireflection film, for obtaining high case hardness, need be typically thin silica granule at a kind of inorganic matter of outermost layer fusion of film, consumption is no less than 30% weight.There is such problem in the antireflection film that obtains with this film composition, and promptly because surperficial sliding is poor, film is easy to be scratched by cloth or analog.
For overcoming the problems referred to above, proposed various surface conditioning agents, and put in the market.Since in any all water solubles or solvent in them, all be temporary transient in case be used for its effect of surface, can not be lasting.Japanese Patent Application Publication JP flat-3266801 has described a kind of fluoro resin layer, and it makes film have drainage.The formation of fluoro resin layer has strengthened the drainage of film, but does not bring satisfied abrasionproof or anti-behaviour's result.
The surface treatment that has been found that the perfluoro-polyether compound is for improving abrasionproof or antiscuffing properety or anti-contamination characteristic is very effective, but chemical stability significantly reduces, as when handling with solvent.This is considered to and lip-deep SiO
