＜anti-dazzle property layered product 〉
Anti-dazzle property layered product of the present invention is to press aftermentioned antiglare hardcoat (B) to form on the upper strata of one side at least of aftermentioned base material (A).
Among the present invention, the half breadth W that the projection frequency projection that mapping obtains to rising height on the surface of antiglare hardcoat (B) is distributed is necessary for 500nm～1500nm.The height H that half breadth W that above-mentioned projection distributes and projection distribute is by by non-contact optical roughmeter (ZYGO corporate system: the surface profile that trade name NewView5022) obtains (profile), by Histogram Plot, making transverse axis is rising height (unit: nm), the longitudinal axis is frequency (unit: counting (the Counts)) projection that obtains half breadth and the height in distributing of mapping.
If the half breadth W that projection distributes is in above-mentioned number range, the then transparency, glossiness, anti-dazzle property excellence, and their balance excellence.In addition, can reduce bright spot.When half breadth W is too small, there is the trend of glossiness increase, has the trend of anti-dazzle property difference.In addition, the trend that exists bright spot to increase.On the other hand, when half breadth W was excessive, there was the poor trend of the transparency in the trend that exists mist degree to increase.Consider that from this viewpoint half breadth W is 550nm～1200nm more preferably, is preferably 700nm～1000nm especially.
In addition, in the present invention, be preferably the half breadth W that the projection frequency projection that mapping obtains to rising height with the surface of antiglare hardcoat (B) distributes (unit: nm) and the height H (unit: counting) satisfy the mode of following formula (1) that distributes of projection.
H≤23×W …(1)
If the height H that half breadth W that projection distributes and projection distribute then can further reduce bright spot in the number range that satisfies following formula (1).In following formula (1), compare the left side with the right when excessive, the trend that exists bright spot to increase.
The height H that projection distributes is preferably 5000 (counting)～29500 (counting).If the height H that projection distributes is in above-mentioned number range, then the balance of the transparency, glossiness and anti-dazzle property is more excellent.In addition, can further reduce bright spot.When the height H that projection distributes is too high, the trend that exists bright spot to increase.On the other hand, cross when hanging down, the trend that exists glossiness to increase, the raising effect of anti-dazzle property reduces.Consider that from this viewpoint the height H that projection distributes is 8000 (counting)～25000 (counting) more preferably, are preferably 10000 (counting)～20000 (counting) especially.
The height H that half breadth W that the projection on the surface that makes antiglare hardcoat (B) is distributed and projection distribute does not limit especially in the method for above-mentioned number range.Can realize by in antiglare hardcoat (B), adding specific particle, also can realize by making antiglare hardcoat (B) be separated, utilize this to be separated, can also be by chemistry being carried out on the surface of antiglare hardcoat (B) or physical treatment realizes.Wherein, add the method for specific particle owing to can stablize and carry out with comparalive ease and preferred.
Among the present invention, as being used to form the particularly preferred method that height H that half breadth W that projection distributes and projection distribute satisfies the mode of afore mentioned rules, can enumerate the method for the average grain diameter of the average grain diameter of suitable adjustment organic filler described later (C) and content, inorganic particulate (D) and content, the cohesion mode of inorganic particulate (D), the thickness of antiglare hardcoat (B) etc.Wherein, the part of inorganic particulate (D) mode of condensing in antiglare hardcoat (B) is important.When average grain diameter by organic filler (C), inorganic particulate (D) or content are adjusted, if increase the average grain diameter of organic filler (C), the trend that the half breadth W that then exists projection to distribute reduces, the trend that the height H that exists projection to distribute simultaneously increases.If increase the content of organic filler (C), the trend that the height H that then exists projection to distribute increases.If increase the average grain diameter or the content of inorganic particulate (D), the trend that the half breadth W that then exists projection to distribute increases.In addition, in order to satisfy following formula (1), making the content of organic filler (C) fewer is that effectively for example this content is to be effective below the 3.5 quality %.Further, making the ratio T/d (C) of average grain diameter d (C) of the thickness T of antiglare hardcoat (B) and organic filler (C) smaller also is effectively, should be to be effective below 2.4 than T/d (C) for example.They are made up to adjust be effective especially.
Above-mentioned anti-dazzle property layered product be preferably and have the surface undulation composition on the surface of this antiglare hardcoat (B) (
) form.By forming this form, the half breadth W that projection is distributed is above-mentioned number range, easily forms preferred surface configuration among the present invention.The surface undulation composition is different with sharp-pointed projection, and expression is present in the protuberance of mitigation on the surface of antiglare hardcoat (B).According to the inventor's cross-section, infer that this surface undulation composition is to form by the condensation product of inorganic particulate described later (D) or the further aggregate that forms of gathering of condensation product of inorganic particulate (D).Above-mentioned surface undulation composition is preferably dimensioned to be 10 μ m～90 μ m, and more preferably 20 μ m～85 μ m are preferably 30 μ m～50 μ m especially.Size by making the surface undulation composition is in above-mentioned number range, makes half breadth W that projection distributes in above-mentioned number range easilier, easily forms further preferred surface configuration.The size of above-mentioned surface undulation composition can reach by suitably adjusting the condensation product of inorganic particulate (D) or the size of aggregate.
The 60 degree glossiness on the surface of the anti-dazzle preferred antiglare hardcoat of property layered product of the present invention (B) are 100～150.If 60 degree glossiness are in above-mentioned number range, then the balance of the transparency, glossiness and anti-dazzle property is more excellent.60 degree glossiness are crossed when hanging down, the trend that exists the transparency to reduce, and the raising effect of visuognosis degree reduces.On the other hand, when 60 degree glossiness are too high, there is the trend of anti-dazzle property difference.Consider that from this viewpoint 60 degree glossiness more preferably 112～140 are preferably 117～133 especially.Above-mentioned 60 degree glossiness can be by suitably adjusting average grain diameter, the content of organic filler described later (C) and inorganic particulate (D), or the thickness of suitably adjusting antiglare hardcoat (B) reaches.
In addition, the preferred mist degree of anti-dazzle property layered product of the present invention is 0.5%～3.5%.When mist degree is too high, the trend that exists the transparency to reduce, the raising effect of visuognosis degree reduces.Though preferred mist degree is low, in order to reduce mist degree, is necessary to reduce the addition that adds the particle in base material, the antiglare hardcoat to usually, or reduces particle diameter, produce problems such as easy damaged base material thus, so lower limit is preferably more than 0.5%.Consider from this viewpoint, mist degree more preferably 0.7%～2.7%, more preferably 0.9%～1.9%, be preferably 1.1%～1.6% especially.Above-mentioned mist degree can adjust the refractive index of organic filler (C), or the transparency of adjustment base material reach by suitably adjusting average grain diameter, the content of organic filler described later (C) and inorganic particulate (D).
