Problems solved by technology

[0004] In recent years, in the production process of liquid crystal display panels, although the number of occurrences is small, the following phenomenon has occurred: due to the peeling static voltage generated when the surface protective film bonded to the optical film is peeled off Phenomenon in which circuit components such as driver ICs that control the display screen of a liquid crystal display panel are damaged, or the alignment of liquid crystal molecules is damaged

Embodiment 1

[0163] Nitrogen gas was introduced into a reaction device equipped with a stirrer, a thermometer, a reflux cooler, and a nitrogen introduction pipe, and the air in the reaction device was replaced with nitrogen gas. Afterwards, in reaction unit with the methyl acrylate of 10 weight parts, the 2-ethylhexyl acrylate of 90 weight parts, the acrylate-8-hydroxyoctyl ester of 5.0 weight parts, the polypropylene glycol monoacrylate (n =12) Add 60 parts by weight of solvent (ethyl acetate) together. After that, 0.1 parts by weight of azobisisobutyronitrile as a polymerization initiator was added dropwise over 2 hours, and reacted at 65°C for 6 hours to obtain the acrylic polymer solution of Example 1 with a weight average molecular weight of 500,000. . After adding 8.5 parts by weight of acetylacetone to this acrylic polymer solution and stirring, 2.0 parts by weight of CORONATE HX (isocyanurate body of hexamethylene diisocyanate compound) and 0.1 part by weight of titanium triacetyl...

Embodiment 2～6 and comparative example 1～3

[0165] Except that the composition of the adhesive composition of Example 1 was set as described in Table 1 and Table 2, the adhesive agent combinations of Examples 2 to 6 and Comparative Examples 1 to 3 were obtained in the same manner as in Example 1. things. In Table 1 and Table 2, the monomers (to be copolymerized) contained in the acrylic polymer are (A), (B), (F), and "carboxyl group-containing monomers".

Abstract

The present invention provides an antistatic surface-protective film having excellent peeling and electrostatic resistance properties without polluting an adherent and without being deteriorated over time. An adhesive layer (2) formed from an adhesive composition is formed on one surface of a base film (1), and a release film (5) on which a release agent layer (4) is laminated, wherein an antistatic agent of the release agent layer (4 ) is transferred onto the surface of the adhesive layer (2), and the adhesive composition contains acrylic polymer, and further comprises: (C) an isocyanate compound having two or more degrees of functionality, (D) a crosslinking accelerator and (E) a ketone-enol tautomer. The acrylic polymer is made from 1-30 by weight part of (a1), 70-99 by weight part of (a2), and 0.1-12 by weight part of (B) through copolymerization, wherein (a1) is a (methyl) acrylate monomer having alkyl group with a C1 to C4 carbon number, (a2) is a (methyl) acrylate monomer having alkyl group with a C5 to C18 carbon number, and (B) is a hydroxyl group-containing copolymerizable monomer.

Description

technical field [0001] The present invention relates to an antistatic surface protection film, and in more detail, relates to a preparation method of an antistatic surface protection film with antistatic performance, and an antistatic surface protection film; providing an antistatic surface protection film with less pollution to adherends, And the preparation method of the antistatic surface protection film which does not deteriorate with time and has excellent anti-static stripping performance, and the antistatic surface protection film. Background technique [0002] Production and transportation of optical films such as polarizers, retardation plates, lens films for displays, antireflection films, hard coat films, transparent conductive films for touch panels, and displays using these films At the time of production, a surface protection film is attached to the surface of the optical film to prevent dirt and scratches on the surface in the subsequent process. Regarding th...
