Embodiment 1

[0168]

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

[0170]

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

Embodiment 2～20、 comparative example 1～2

[0175] As shown in Table 1 and Table 2, the monomer components constituting the acrylic polymer, the crosslinking agent constituting the adhesive composition, the catalyst, and the type or mixing amount of the keto-enol tautomeric compound were changed. Other than that, the carrier film for transparent conductive films was produced by the same method as Example 1.

Abstract

The present invention relates to a carrier film for a transparent conductive film and a laminate. The present invention provides a carrier film for a transparent conductive film capable of suppressing the occurrence of irregularities on the paste surface and the occurrence of the zipper phenomenon. A carrier film for a transparent conductive film, which has an adhesive layer on at least one side of a support, and the adhesive layer is formed from an adhesive composition, and the adhesive composition contains: a glass transition temperature of A (meth)acrylic polymer (A) obtained by polymerizing a monomer component containing an alkyl (meth)acrylate and a hydroxyl group-containing monomer at a temperature below -50°C, an isocyanate crosslinking agent (B), and Catalyst (C) having iron as the active center.

Description

Technical field [0001] The present invention relates to a carrier film for a transparent conductive film having a support 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 electroluminescence (EL) panels, electrochromic panels, electronic paper elements, etc., the demand for elements using film substrates provided with transparent electrodes on plastic films 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 the film substrate including the ITO thin films and silver nanowire thin films tends to become thinner year by year. [0004] In addition, in most cases, an anti-reflection (AR) layer is provided as a functional layer on a film s...
