Description
Technical field
The present invention relates to anti-dazzle hardness film coating.More particularly; relate to a kind of anti-dazzle hardness film coating; it can not reduce high-accuracy demonstration image quality; can give good anti-dazzle property; be used for various indicating meters for example liquid-crystal display (LCD), plasma display (PDP), cathode ray tube (CRT) and when using visual good (expression sharpness height) as touch panel etc.; can increase surface hardness, be suitable as surface protection film.
Background technology
In the display screen of CRT and liquid crystal display etc., light is injected from the picture outside, this luminous reflectance (being called as dazzle or thorn sight (ギ ラ Star キ) etc.), the situation that appearance is difficult to see display image, particularly in recent years, along with the maximization of display screen, addressing the above problem becomes more and more important problem.
In order to address this is that, so far various display screens various non-glare treated have been carried out.As one of them, for example in liquid crystal display, the hard coat film that uses in the polaroid and the protection of various display screen are carried out the non-glare treated of surface roughening with hard coat film etc.The anti-dazzle processing method of this hard coat film can be divided into (1) usually and adopt physical method to carry out the method two big classes that the method for surface roughening and (2) are forming mixed fillers in the hard paint that hard coat uses when the curing that forms hard coat.
In these two kinds of methods, the method for latter's mixed fillers in hard paint is a main stream approach, and, as filler, mainly use silica granule.As the reason of using silica granule, can enumerate the whiteness that can suppress the gained hard coat film and descend, and favorable dispersity etc. can not reduce hardness, and sneak into paint the time.
But,,,,, also can produce the unavoidable problem that descends of its image quality even then the liquid crystal display knuckle is high-accuracy if use in the past non-high-accuracy hard coat film (feeling coarse) as above-mentioned anti-dazzle hardness film coating for example when liquid crystal display when being high-accuracy.Therefore, in order to obtain the high image quality that high-accuracy liquid crystal display possesses, high-accuracy anti-dazzle hardness film coating must be arranged.
In the former anti-dazzle hardness film coating, using median size usually is silica granule about 1～2.5 μ m.The anti-dazzle property of this silica granule is good, but can not adapt in recent years high-accuracyization liquid crystal display etc., and makes it show image quality reduction.
Practical situation are, in the anti-dazzle hardness film coating of silica granule that this independent use median size is 1～2.5 μ m, also do not find can not make the image quality reduction of high-accuracyization liquid crystal display in recent years and can give the hard coat film of good anti-dazzle property as filler.
Therefore, attempted making the method (referring to for example patent documentation 1) that contains colloided silica particle aggregation thing in the hard coat, made combination in the hard coat contain atomic method (referring to for example patent documentation 2) that silica granule that median size is 0.5～5 μ m and median size be 1～60nm etc., but need further promote clearness.
In addition, disclose also on transparency carrier that to form by specific refractory power be the scuff resistance anti-dazzle film (referring to for example patent documentation 3) that antiglare layer that 1.40～1.60 resin beads and ionizing ray curable resin composition constitute forms.In this anti-dazzle film, as preferred resin beads, using particle diameter is polymethylmethacrylate bead, polycarbonate pellets, polystyrene sphere, polypropylene vinylbenzene bead, the polyvinyl chloride bead of 3～8 mu m ranges, and, in order to prevent the sedimentation in paint of these resin balls, in per 100 weight part ionizing ray curable resins, the particle diameter that adds about less than 0.1 weight part is 0.5 μ m or following silica bead.
Like this, in above-mentioned communique,, in antiglare layer, disperseed the relatively large typical resin beads of particle diameter, but the not necessarily enough good problem of scuff resistance of antiglare layer occurred in order to give anti-dazzle property.

Table 2
From table 1 and table 2, as can be seen, when the hard coat film among the embodiment is all keeping anti-dazzle property and have higher expression boldness, and has higher hardness.Though and the hard coat film in the comparative example all has higher hardness, represent that boldness is obviously lower, all light transmittance is also lower.
Anti-dazzle property film of the present invention is the surface hardness height not only, and is being used for various indicating meters, and during such as liquid-crystal display, plasma display, cathode tube even touch panel etc., visuality is also good when having anti-dazzle property.
