Optical film having adhesive agent, and optical laminated body in which same is used
An adhesive layer and optical film technology, applied in the field of optical films, can solve the problem of adhesive layer foaming, excellent durability, between the adhesive layer and the adhesive layer, or between the adhesive layer and the liquid crystal cell glass. Problems such as floating and peeling occur between them, and the effect of suppressing electrification, excellent durability, and excellent reworkability is achieved.

[0288] [Examples 1 to 13 and Comparative Examples 1 to 2]
[0289] (a) Manufacture of adhesive
[0290] Using 20% ethyl acetate solutions of acrylic copolymers prepared in Polymerization Examples 1-13, the ionic compound and crosslinking agent "CORONATE L" were adjusted to the amounts shown in Table 2 with respect to 100 parts of each solid content. And the silane-based compound "KBM-403" was mixed in an amount of 0.5 parts, and ethyl acetate was further added so that the solid content concentration was 13% to prepare an adhesive composition. In addition, as described above, the crosslinking agent "CORONATE L" is an ethyl acetate solution with a solid content of 75%, and the addition amount shown in Table 2 is the amount of the solid content (active ingredient).
[0291] (b) Production of optical film with adhesive
[0292] Using an applicator, each of the above adhesive compositions was applied to a release-treated polyethylene terephthalate film (trade name "PLR-382050", made fro...
Example
[0331] [Examples 14-17 and Comparative Examples 3-6]
[0332] (a) Manufacture of adhesive
[0333] Using the 40% ethyl acetate solution of the acrylic copolymer prepared in Polymerization Examples 14-17, the ionic compound and the crosslinking agent "CORONATE L" were adjusted to the amounts shown in Table 4 with respect to 100 parts of each solid content. (The crosslinking agent "CORONATE L" is the amount of solid content) and the silane compound "KBM-403" is mixed in an amount of 0.5 parts, and ethyl acetate is added so that the solid content concentration is 29% to prepare an adhesive combination Things.
[0334] (b) Production of optical film with adhesive
[0335] Using an applicator, each adhesive composition was applied to a release-treated polyethylene terephthalate film (trade name "PLR-382050", made of The mold-releasing treatment surface obtained by Lintec Co., Ltd.; called a spacer) was dried at 100°C for 1 minute to obtain a sheet-shaped adhesive. Next, a protective fil...
