Method for producing anti-glare film, anti-glare film, coating solution, polarizing plate, and image display

摘要

A method for producing an anti-glare film, capable of controlling a flocculation state of particles without depending on flocculation characteristics of the particles and thus capable of forming an anti-glare layer having desired surface asperities. In the method, a coating solution containing a resin, particles, thixotropy-imparting agents, and a solvent and satisfying at least one of the following conditions (I) and (II) is coated on a translucent base and then is sheared and cured,
(I) a contribution ratio R 2 is 0.95 or more in a linear approximate equation of the amount of the thixotropy-imparting agents to be added and the Ti value which is defined by the following equation (A) and in the range from 1.2 to 3.5,
(II) a quadratic coefficient a is a negative value in a quadratic polynomial approximate equation, y = ax 2 + bx + c of the amount x of the thixotropy-imparting agents to be added and the Ti value y which is defined by the following equation (A) and in the range from 1.2 to 3.5, Ti value = ß �¢ 1 / ß �¢ 2
where in the equation (A),
ß1: viscosity at shear rate of 20 (1/s)
ß2: viscosity at shear rate of 200 (1/s).
