Embodiment 1

[0168]

[0169] In a four-necked flask with a stirring blade, a thermometer, a nitrogen inlet tube and a condenser, 100 parts by weight of 2-ethylhexyl acrylate (2EHA), 10 parts by weight of 4-hydroxybutyl acrylate (HBA), 0.2 parts by weight 2,2'-Azobisisobutyronitrile and 205 parts by weight of ethyl acetate as a polymerization initiator, nitrogen gas was introduced while stirring slowly, and the liquid temperature in the flask was kept at about 63°C for about 4 hours. Polymerization reaction, Thus, an acrylic polymer (A1) solution (about 35% by weight) was prepared. The acrylic polymer (A1) had a weight average molecular weight of 600,000 and a Tg of -67°C.

[0170]

[0171] The above-mentioned acrylic polymer (A1) solution (about 35% by weight) was diluted to 29% by weight with ethyl acetate, and 4 parts by weight of trimethylol was added to 100 parts by weight (solid content) of the acrylic polymer in the solution. Propane / toluene diisocyanate trimer adduct (manufactu...

Embodiment 2～20、 comparative example 1～2

[0175] As shown in Table 1 and Table 2, the types or compounding amounts of the monomer components constituting the acrylic polymer, the crosslinking agent constituting the adhesive composition, the catalyst, and the keto-enol tautomeric compound were changed. Except that, the carrier film for transparent conductive films was produced by the method similar to Example 1.

Abstract

A carrier film for transparent conductive films of the invention includes a support and a pressure-sensitive adhesive layer provided on at least one side of the support, wherein the pressure-sensitive adhesive layer is made from a pressure-sensitive adhesive composition including: a (meth)acryl-based polymer (A) having a glass transition temperature of −50° C. or lower and obtained by polymerization of a monomer component containing an alkyl(meth)acrylate and a hydroxyl group-containing monomer; an isocyanate crosslinking agent (B); and a catalyst (C) having an iron active center. The carrier film for transparent conductive films, with which the formation of irregularities on an adherend surface and zipping can be prevented.

Description

technical field [0001] The present invention relates to a carrier film for a transparent conductive film having a support body and an adhesive layer. Moreover, this invention relates to the laminated body which has this carrier film for transparent conductive films, and a transparent conductive film. Background technique [0002] In recent years, in touch panels, liquid crystal display panels, organic electroluminescent (EL) panels, electrochromic panels, electronic paper components, etc., the demand for components using a film substrate in which a transparent electrode is provided on a plastic film is increasing . [0003] As materials for transparent electrodes, ITO thin films (In-Sn composite oxides) and silver nanowire thin films are currently used, and the thickness of film substrates including the ITO thin films and silver nanowire thin films tends to decrease year by year. [0004] In addition, in many cases, an anti-reflection (AR) layer is provided as a functional...
