<p>In the present invention, provided is an acrylic resin particle which forms optical materials with uniform light diffusion properties. The acrylic resin particle of the present invention hasαvalue,γvalue andηvalue which are satisfied with a certain relationship wherein theαvalue means 10% of the diameter of accumulated particles with respect to volume is divided by 10% of the diameter of accumulated particles with respect to numbers;γvalue means 50% of the diameter of accumulated particles with respect to volume is divided by 50% of the diameter of accumulated particles with respect to numbers; andηvalue means 90% of the diameter of accumulated particles with respect to volume is divided by 90% of the diameter of accumulated particles with respect to numbers. In addition, the acrylic resin particle of the present invention has a CV value, an A value and a B value wherein the CV value of the diameter of particles with respect to volume is 30 to 40%; the A value is not less than 0.75 obtained by dividing 10% of the diameter of accumulated particles with respect to volume by 50% of the diameter of accumulated particles with respect to volume; and the B value is 1.1 to 1.6 obtained by dividing 90% of the diameter of accumulated particles with respect to volume by 50% of diameter of accumulated particles with respect to volume.</p> |
