Problems solved by technology

[0004] However, as the colorization of CRT and flat-panel displays has progressed, as a result of the progress in the finer color of various displays, if the conventional anti-Newton ring film is used as a touch panel, the particles contained in the anti-Newton ring layer will change. As a result, a dazzling phenomenon called flicker occurs, resulting in the problem that high-definition color images look dazzling

Embodiment 1

[0108] As a transparent body, on one side of a polyester film (Cosmosiyain A4300: Toyobo Co., Ltd.) with a thickness of 188 μm, the coating liquid for the Newton ring prevention layer of the following formulation was coated, dried, and subjected to ultraviolet light under a high-pressure mercury lamp. Irradiated to form an anti-Newton ring layer with a thickness of 1.5 μm, thereby producing the anti-Newton ring film of Example 1.

[0109]

[0110] ・Ionizing radiation curable organic-inorganic composite resin 100 parts

[0111] (solid content 50%) (inorganic content 38%)

[0112] (デソライト7503: JSR Corporation)

[0113] · Microparticles (acrylic resin particles) 0.2 parts

[0114] (average particle size 2μm) (coefficient of variation 50%)

[0115] 150 parts of isopropyl alcohol

Embodiment 2

[0117] Except that the microparticles of the coating solution for the Newton ring prevention layer in Example 1 are replaced by propylene-based resin particles with an average particle diameter of 2 μm and a coefficient of variation of 33%, other all adopt the same method as in Example 1 to make and implement Example 2 of the Newton ring prevention film.

Embodiment 3

[0119] Except that the particles of the coating solution for the Newton-ring prevention layer in Example 1 were replaced with propylene-based resin particles with an average particle diameter of 9 μm and a coefficient of variation of 22%, to make a Newton-ring prevention layer with a thickness of 7 μm, the other In the same manner as in Example 1, the anti-Newton ring film of Example 3 was produced.

Abstract

A sheet (1) for preventing a Newton's ring which comprises a transparent support (2) and, formed on one surface thereof, a layer (3) for preventing a Newton's ring comprising an organic-inorganic hybrid resin (a binder component (32)) of ionizing radiation curing type and fine particles (31), wherein, preferably, the fine particles (31) have an average particle diameter of 0.5 to 3.0 mum and a coefficient of variation for a particle diameter of 20 to 80 %, and the layer (3) for preventing a Newton's ring has a thickness of 0.2 to 3.5 mum; and a touch panel using the sheet for preventing a Newton's ring. The above sheet for preventing a Newton's ring is excellent in the property of preventing a Newton's ring and provides a touch panel which is less susceptible to sparkling even when used in a panel having a highly fine and precise color display.

Description

technical field [0001] The present invention relates to an anti-Newton ring film, and particularly relates to an anti-Newton ring film used for a touch panel used on a display screen such as a CRT or a flat panel display. Background technique [0002] For a long time, in the fields of photo-engraving and optical equipment, there has been a problem of Newton's rings when plastic films or glass plates are bonded together. By maintaining the gap between the two members at a certain level or more during bonding, the occurrence of Newton's rings can be prevented. Therefore, it has been proposed to obtain an anti-Newton ring film with one or both sides of the member subjected to roughening treatment by sandblasting the surface of the member or by forming an anti-Newton ring layer composed of a binder component and fine particles on the member. . (Refer to Patent Document 1). [0003] On the other hand, on members such as film and glass used in touch panels used on display scree...
