no. 1 approach

[0067] Figures 1A-1C is an explanatory diagram illustrating one example of the first embodiment of the production method of the antiglare film, and figure 2 is a schematic diagram illustrating one example of a production apparatus of an antiglare film. In this embodiment, description will be made by using an example of a coating liquid containing two kinds of resins A and B, however the case of two or more resins also has the same basic concept.

[0068] (Coating liquid preparation step)

[0069] The production method of the antiglare film according to the present invention firstly includes preparing a coating solution for forming an antiglare layer in which two mutually incompatible resins A and B are dissolved in a solvent and a low-refractive coating liquid in which the resin and particles are dissolved in a solvent. Coating solution for layer formation.

[0070] As the particle and resin material, those described later can be used. The mixing method is not particular...

no. 2 approach

[0164] Next, a second embodiment according to the present invention will be described.

[0165] Figure 5A and 5B is an explanatory diagram illustrating one example of a method of producing an antiglare film. Explanatory diagram of the preparation equipment for the anti-glare film ( figure 2 ) and the explanatory diagram of the coating device ( image 3 ) are the same as those used in the first embodiment.

[0166] In this embodiment, description is made using an example of a coating liquid comprising a first polymer whose substituent has a molecular structure that lowers the refractive index of the entire polymer and three types of resins A, B and C, the substituents of these three types of resins do not contain a molecular structure that lowers the refractive index of the entire polymer, but the case of three or more resins whose substituents do not contain a molecular structure that lowers the refractive index of the entire polymer is also the case. have the same basi...

[0210] (upper layer, low refractive index layer)

[0211] The surface of the hollow silica particles having an average particle diameter of 20 nm was treated with 3,3,3-trifluoropropylmethyldichlorosilane to hydrophobize the surface of the particle. A coating liquid was prepared by dissolving the composition shown below in 82 parts by mass of methyl ethyl ketone. The critical solid concentration of this system is 71%.

Abstract

A process for antiglare film production which comprises: a step in which a coating fluid for antiglare layer formation and a coating fluid for low-refractive-index layer formation are prepared, the coating fluids each containing an ingredient capable of localizing; a coating step in which the coating fluid for low-refractive-index layer formation and the coating fluid for antiglare layer formation are applied to a support to form an upper coating layer and a lower coating layer, respectively; and a drying step in which the coating layers are dried and caused to undergo phase separation, whereby the ingredients localize and an antiglare layer and a low-refractive-index layer are formed. By the process, an antiglare film which inhibits a display from suffering external-light reflection thereon, glittering, and the whitening caused by irregular reflection can be produced at low cost.

Description

technical field [0001] The present invention relates to a method for producing an antiglare film for various displays, and particularly to a method for producing an antiglare film that can suppress reflection and glare of external light on a display and whitening due to irregular reflection method. Background technique [0002] A common problem with various displays such as cathode ray tube displays, liquid crystal displays, plasma displays, and organic EL displays, etc., is that if indoor fluorescent lights, outside sunlight, etc. are reflected on the display, it is difficult to view the display well due to the reflected light . In order to solve this problem, an anti-glare film is disposed on the surface of the display to scatter reflected light from a light source, thereby improving visibility. [0003] As such an antiglare film, many types have been proposed, but for example, Patent Document 1 shown below discloses a method in which particles such as resin beads are us...
