[0207] (5) Production method of film for transparent conductive film lamination
[0208] The film for transparent conductive film lamination of this embodiment can be obtained by the manufacturing method containing the following process (a)-(b), for example.
[0209] (a) Step of forming a hard coat layer on both surfaces of the film substrate for laminating a transparent conductive film
[0210] (b) Step of forming an optical adjustment layer on one hard coat layer
[0211] (5)-1 Step (a): Step of forming a hard coat layer
[0212] On both sides of the film for laminating a transparent conductive film, the above-mentioned composition for forming a hard coat layer is coated by a conventionally known method, and after forming a coating film, it is dried, and the coating film is cured by irradiating it with active energy rays. Forms a hard coat.
[0213] Moreover, as a coating method of the composition for hard-coat layer formation, a bar coater, a knife coater, a roll coater,...
Embodiment 1
[0313] 1. Preparation of film for transparent conductive film lamination
[0314] (1) Preparation of a composition for forming a hard coat layer
[0315] Active energy ray-curable resin as component (A), silica microparticles as component (B), leveling agent as component (C), and photopolymerization initiator as component (D) are contained in the following composition After being put in the container, a solvent was added and uniformly mixed to prepare a composition for forming a hard coat layer having a solid content concentration of 16% by weight.
[0316] In addition, the following composition and the addition amount of the composition shown in Table 1 represent the purity except the diluent solvent.
[0317] (A) Component: 100 parts by weight of dipentaerythritol hexaacrylate
[0318] (B) Component: 20 parts by weight of reactive solid silica particles
[0319] (Volume average particle diameter (D50) 15nm)
[0320] (C) Component: 0.05 parts by weight of fluorine levelin...
Embodiment 2
[0394] In Example 2, a laminate was prepared and evaluated in the same manner as in Example 1 except that the adhesive composition of the adhesive layer was changed when preparing the protective film. The details of the acrylic pressure-sensitive adhesive composition are as follows. In addition, the obtained results are shown in Table 1.
[0395]
[0396] A (meth)acrylate copolymer having a weight average molecular weight of 500,000 was obtained by normal solution polymerization at butyl acrylate / acrylic acid=100 / 5 (weight ratio). An acrylic pressure-sensitive adhesive composition was obtained by adding 5 parts by weight of N,N,N',N'-tetraglycidyl-m-xylylenediamine as an epoxy-based crosslinking agent to 100 parts by weight of the copolymer.
