Embodiment 1

[0175]

[0176] In a four-necked flask with a stirring blade, a thermometer, a nitrogen inlet tube and a condenser, 90.98% by weight of 2-ethylhexyl acrylate (2EHA), 9.00% by weight of 4-hydroxybutyl acrylate (HBA) and acrylic acid (AA ) 0.02% by weight of 100 parts by weight of monomer components, 0.2 parts by weight of 2,2'-azobisisobutyronitrile as a polymerization initiator, and 205 parts by weight of ethyl acetate. The liquid temperature of the solution was kept at about 63° C. and a polymerization reaction was performed for about 4 hours, thereby preparing an acrylic polymer (A1) solution (about 35% by weight). The acrylic polymer (A1) had a weight average molecular weight of 650,000 and a Tg of -67.6°C.

[0177]

[0178] The above-mentioned acrylic polymer (A1) solution (about 35% by weight) was diluted to 29% by weight with ethyl acetate, and 12 parts by weight of hexamethylene was added to 100 parts by weight (solid content) of the acrylic polymer in the solution....

Embodiment 2～10、 comparative example 1～4

[0182] As shown in Table 1 and Table 2, the monomer components constituting the (meth)acrylic polymer, the crosslinking agent constituting the adhesive composition, the catalyst, and the type or combination of the keto-enol tautomeric compound were changed. amount, except that, the carrier film for transparent conductive films was produced by the method similar to Example 1.

Abstract

The invention relates to a carrier film for a transparent conductive film and a laminated body. The invention provides the carrier film for the transparent conductive film. The carrier film for the transparent conductive film can maintain an appropriate adhesive force in a condition that changes occur to aging environments. According to the carrier film for the transparent conductive film, at least a single surface of a support body has an adhesive layer, wherein the adhesive layer is formed by adhesive composites. The adhesive composites contain (methyl) acrylic polymers (A) and aliphatic polyisocyanic acid ester cross-linking agents (B). A glass transition temperature of the (methyl) acrylic polymers (A) is below minus 50 DEG C. The (methyl) acrylic polymers (A) is obtained through polymerization of 59.5-91 % by weight of (meth) acrylic acid alkyl esters with a carbon atom number being 2-14, 8.5-40 % by weight of hydroxyl-containing monomers, 0.001-0.5 % by weight of carboxylic-containing monomers and 0-10 % by weight of other monomers and other copolymerization monomer composition relative to the amount of monomer composition total quantity.

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 the material of the transparent electrode, ITO thin film (In-Sn composite oxide), metal thin film such as silver or copper, silver nanowire thin film are used at present, and the film base material that comprises said ITO thin film, metal thin film, silver nanowire thin film The thickness tends to become thinner year by year. [0004] In addition, i...
