Problems solved by technology

[0007] However, as a result of confirmation by the present inventors, it has been found that the following proposals have not yet been obtained for the thin film laminate by focusing on the interface between the light-transmitting base material and the antistatic layer and the interface between the antistatic layer and the hard coat layer. interface, improve its interface state, to achieve a proposal to effectively prevent interface reflection and interference fringes

Embodiment 1

[0141] Prepare a light-transmitting base material (triacetyl cellulose resin film with a thickness of 80 μm (manufactured by Fuji Photo Film Co., Ltd., TF80UL), and apply the composition 1 for the antistatic layer on one side of the film using a coiled wire coating bar. Keep it in a hot oven at 70°C for 30 seconds to evaporate the solvent in the coating film, and then irradiate ultraviolet light so that the accumulated light amount reaches 98mj to cure the coating film and form a 0.7g / cm 2 (dry) transparent antistatic layer, thereby preparing an antistatic laminated body. Afterwards, apply the composition for the hard coat layer, keep it in a hot oven at a temperature of 70° C. for 30 seconds to evaporate the solvent in the coating film, and then irradiate the ultraviolet rays so that the cumulative light amount reaches 46 mj to cure the coating film to form a 15 g / cm 2 (dry) hard coat layer, thereby preparing a thin film laminate.

Abstract

Disclosed is a thin film laminate wherein interface reflection and interference patterns are effectively prevented by substantially eliminating an interface. The thin film laminate comprises a light-transmitting base and an antistatic layer and hard coat layer arranged on the light-transmitting base in this order. This thin film laminate is characterized in that there is substantially no interface between the light-transmitting base and the antistatic layer and / or there is no interface between the antistatic layer and the hard coat layer.

Description

technical field [0001] The present invention relates to a thin film laminate that prevents interface reflection and interference fringes. Background technique [0002] The display surface of an image display device such as a liquid crystal display (LCD) or a cathode tube display device (CRT) is required to reduce reflection caused by light irradiated from an external light source such as a fluorescent lamp and improve visibility. In this regard, by covering the surface of a transparent object with a transparent film with a low refractive index, a film laminate (for example, an anti-reflection laminate) that can reduce reflectivity is equipped, thereby reducing the surface area of ​​the display surface of the image display device. Reflective for improved visibility. [0003] As a method for producing a thin film laminate capable of realizing antireflection, wet coating methods of coating a coating liquid prepared for forming each layer have become mainstream from the viewpoi...
