Problems solved by technology

In this method, since the anti-reflection layer and the protective layer are connected, it is an advantageous laminated structure for high hardness. However, in order to achieve high hardness, the thickness of the protective layer needs to be increased. Therefore, a large deformation occurs due to shrinkage of the film ( warping), it is difficult to obtain a smooth surface

Embodiment 1

[0138] To the anti-reflection transfer film (manufactured by Oike Industry Co., Ltd., trade name: STEP PAR-1, laminated in the order of film (PET film), release layer, anti-reflection layer, cured coating layer, and adhesive layer) The side of the adhesive layer is vertically and linearly coated with a coating formed by an ultraviolet curable mixture, which is composed of 35 parts by mass TAS, 30 parts by mass C6DA, 10 parts by mass M305, 25 parts by mass 1 part M400, 2 parts by mass of DAROCUR TPO, and a planar coating was formed using a bar coater (No. 50). In addition, the anti-reflection transfer film is not directly used as a roll-shaped film, but is cut out from a roll-shaped film and stored as a flat film.

[0139] Then, on a 2mm-thick acrylic resin substrate (ACRYLITE EX001) heated to 60°C, the anti-reflection transfer film with the above-mentioned coating layer was formed so that the coating layer faced the side of the resin substrate and the above-mentioned transfer ...

Embodiment 2

[0145] Except having changed the film thickness of the 2nd cured coating film layer in Example 1 as shown in Table 1, it carried out similarly to Example 1, and produced the resin laminated body. The results are shown in Table 1.

Embodiment 3

[0147] Except having changed the film thickness of the 2nd cured coating film layer in Example 1 as shown in Table 1, it carried out similarly to Example 1, and produced the resin laminated body. The results are shown in Table 1.

Abstract

Disclosed is a method for manufacturing a resin laminated body that is minimally warped and that has excellent adhesiveness and abrasion resistance. The method includes: a first step wherein, to form a coating layer, a solventless activation energy line-hardening mixture is applied to the adhesion layer of a transfer film formed by sequentially forming a release layer, an antireflective layer, a first cured coating layer, and the adhesion layer on one face of a transparent film; a second step wherein the coating layer side is applied to a resin base material; a third step wherein the activation energy line-hardening mixture in the coating layer is hardened to form a second cured coating layer; and a fourth step wherein the transparent film is peeled off, leaving the second cured coating layer, the adhesion layer, the first cured coating layer, and the antireflective layer stacked on the resin base material.

Description

technical field [0001] The present invention relates to a plate-shaped resin laminate having excellent transparency, antireflection performance, and scratch resistance, which is suitable for applications such as display front panels, and a method for producing the same. Background technique [0002] Transparent resins such as acrylic resins and polycarbonate resins are widely used as industrial materials and construction materials. Especially in recent years, due to its transparency and impact resistance, it has been increasingly used in the front panels of various displays such as CTRs, LCD TVs, and plasma displays. [0003] In recent years, one of the important performances required of front panels includes, for example, antireflection performance, which is a function for reducing reflected light from indoor fluorescent lamps irradiating the front panel and displaying images more clearly. As one of the principles of the anti-reflection function, an anti-reflection film ha...
