【Table 1】
To being carried out with the observation result of the relevant a part of polymer particle of alcohols solvent distributed test evaluation result in table 1
Explanation.Fig. 1 and Fig. 2 is the image for indicating the dispersity of the polymer particle of embodiment 1 in alcohols solvent distributed test.Figure
3 and Fig. 4 is the image for indicating the dispersity of the polymer particle of comparative example 2 in alcohols solvent distributed test.Fig. 1 shows poly-
Dispersities of the polymer particle A in isopropanol, Fig. 2 indicate the dispersities of polymer particle A in methyl alcohol.In addition, Fig. 3 tables
Show that dispersities of the polymer particle H in isopropanol, Fig. 4 indicate the dispersities of polymer particle H in methyl alcohol.Compare figure
1~Fig. 4 is it is found that in Fig. 1 and Fig. 2, the substantially uniform dispersions of polymer particle A, and in Fig. 3 and Fig. 4, polymer particle has part
Cohesion, does not obtain uniform dispersity.As shown in Figure 3 and Figure 4, polymer particle H either isopropanol solvent still
Methanol solvate has localized agglomeration, and the evaluation result of alcohols solvent distributed test as shown in table 1 is bad "×".
Result shown in table 1 can confirm, the volume average particle size of polymer particle is 5 μm hereinafter, and hydroxyl value is 5.0mgKOH/
G or more and when 15mgKOH/g or less, the evaluation result and anti-glare evaluation result of alcohols solvent distributed test can obtain well
Result.
In addition, when any one in polymer grain size and hydroxyl value exceeds above range, it is bad to may result in anti-glare
Result.Especially hydroxyl value is less than polymer particle H the thinking poorly of in alcohols solvent distributed test of 5.0mgKOH/g, and
It can not also be coated with.Think evenly dispersed in a dispersion medium when hydroxyl value is 5.0mgKOH/g or more, but hydroxyl value is more than
When 15mgKOH/g or when grain size is more than 5 μm, the evaluation result of anti-glare is relatively low.The reason is that when hydroxyl value is excessively high, recognize
During to form film after being coated on base material film, coherency is relatively low and not sufficiently forms and has an impact to anti-glare
Protrusion.In addition, when the volume average particle size of polymer particle is more than 5 μm, it is believed that since the protrusion formed on base material film becomes
Must be precipitous, excessively scatter exterior light.
In turn, in comparative example 2 of the Component units from hydroxyl monomer less than 3 weight %, dispersibility is insufficient, coating
It is difficult.In comparative example 3 of the Component units more than 15%, the dispersibility after being coated and dried is superfluous, cannot obtain desirable solidifying
Poly- property, is as a result unable to get the anti-glare of target.
The present invention can be implemented under the premise of not being detached from its spirit or essential characteristics with other various forms.Therefore
Above-described embodiment is all only example on all points, is explained with cannot limiting.The scope of the invention such as claims
Shown in, not by any constraint of specification text.And belong to the modifications and changes in the equivalency range of claims, all belong to
In in the scope of the present invention.

For the optics such as the optical films such as optical diffusion film, antiglare film, light diffusing sheet component, in addition also in other field using to various
In purposes.
