Additionally, from making scattering of light state homogenize, and come from the viewpoint of making anti-glare stabilisation, preferably make resin Being shaped as of microgranule is spherical.
(ii) volume average particle size
It addition, inventive feature is that to make the volume average particle size of resin particle be the value in the range of 1~2.5 μm.
Reason is, is the value in the range of this by the volume average particle size making resin particle, it is possible to maintain excellent preventing Dizzy property, and also can effectively suppress the generation of dazzle.
That is, if the volume average particle size of resin particle is less than 1 μm, then the situation being difficult to maintain sufficient anti-glare is had. On the other hand, if the volume average particle size of resin particle is more than 2.5 μm, the most especially it is being applicable to the situation of High Resolution Display Under, have the situation being difficult to effectively suppress dazzle to occur.
It is therefore preferable that be the value in the range of 1.2~2.3 μm for making the volume average particle size of resin particle, more preferably Value in the range of 1.3~2 μm.
Additionally, the volume average particle size of resin particle can use laser diffraction and scattering formula particle size distribution device to survey Fixed.
Then, use Fig. 2 illustrate the volume average particle size of resin particle and the dazzle of anti-dazzle hardness film coating and anti-glare it Between relation.
That is, Fig. 2 represents the volume average particle size (μm) that transverse axis is resin particle, and the left longitudinal axis is the dazzle of anti-dazzle hardness film coating (ppi) characteristic curve A and the characteristic curve B of 60 ° of mirror surface lusters (%) that the right longitudinal axis is anti-dazzle hardness film coating.

Confirm, in the case of being applicable to the actual High Resolution Display of more than 280ppi, in order to stable herein The generation of ground suppression dazzle, as long as making the value of the dazzle in characteristic curve A is the value more than 80ppi.
It will therefore be appreciated that be the value more than 80ppi to make the value of dazzle, effectively suppress dazzle, it should make resin micro- The volume average particle size of grain is 2.5 μm value below.
Secondly, from characteristic curve B, 60 ° of mirror surface lusters also have along with the volume average particle size of resin particle becomes The tendency reduced greatly.
Herein, in the case of the display being applicable to reality, in order to stably obtain the anti-glare of regulation, need to make 60 ° of mirror surface lusters are 120% value below.
It will therefore be appreciated that be 120% value below to make 60 ° of mirror surface lusters, stably obtain the anti-dazzle of regulation Property, it should make the value that volume average particle size is more than 1 μm of resin particle.
As previously discussed, from characteristic curve A and B, in order to effectively suppress the generation of dazzle and anti-in order to obtain regulation Dizzy property, it should the volume average particle size making resin particle is the value in the range of 1~2.5 μm.
Additionally, it is preferred that be 50% value below for making the Cv value of resin particle.
Reason is, if this Cv value is the value more than 50%, then particle diameter is more than or less than the granule of volume average particle size Amount increases, and in the case of the amount of big particle diameter increases, has the situation being difficult to suppress the generation of dazzle, in small particle Amount increase in the case of, have the situation being difficult to obtain desired anti-glare.
Therefore, the Cv value more preferably making resin particle is 40% value below, more preferably 30% value below.
Additionally, Cv value refers to the coefficient of variation of the particle diameter distribution shown in following formula (1).
Cv value (%)=(standard deviation particle diameter/volume average particle size) × 100 (1)
It addition, this Cv value can use laser diffraction and scattering formula particle size distribution device to measure.
(iii) addition
It addition, feature of present invention is, the addition making resin particle is relative to the active energy beam as (A) composition Gel-type resin 100 weight portion is the value in the range of 0.1~20 weight portions.
Reason is, in order to make the surface of antiglare hardcoat form micro concavo-convex, and obtains the anti-glare of excellence.
Be i.e. due to, if the addition of resin particle is the value less than 0.1 weight portion, then cannot be at antiglare hardcoat Surface is sufficiently formed micro concavo-convex, has the situation being difficult to obtain desired anti-glare.On the other hand be due to, if resin particle Addition be the value more than 20 weight portions, then have haze value excessive, display display image identification reduce feelings Condition.
Therefore, the addition more preferably making resin particle is relative to the active energy ray-curable as (A) composition Type resin 100 weight portion is the value in the range of 1~15 weight portions, more preferably the value in the range of 3~12 weight portions.
(1)-3 (C) composition: dispersant
