Embodiment 1
[0184] Drop into the four-necked flask: 2.857 parts by mass of silver nanowire dispersion (1) of 17.5 mass %; 26.25 parts by mass of adhesive (A-4) as adhesive (A); adhesive (B-5) 0.75 parts by mass as binder (B); 0.01 parts by mass of polyoxyethylene alkyl ether (manufactured by Nippon Emulsifier Co., Ltd., product name Newcol 2308) as surfactant; and 70.133 parts by mass of pure water as solvent. Then, it was stirred to form a uniform dispersion liquid to prepare a composition containing silver nanowires. Table 5 shows the concentration and mass ratio of each component in the silver-containing nanowire composition of Example 1. For the coating on the substrate, what was diluted 2.5 times with pure water and had a silver nanowire content of 0.2% by mass was used. Furthermore, Table 8 shows the results of the sedimentation test ("storage stability"), coating processability test results, and evaluation results of various physical properties of the silver-containing nanowire co...
Embodiment 2～35
[0186] Except that the ingredients in Example 1 were changed as shown in Tables 2-4, everything else was the same as in Example 1 to obtain a silver-containing nanowire composition. As other components, a silane coupling agent was added in Example 29, a polyisocyanate compound was added in Example 30, a basic tackifier was added in Example 31, and a polyurethane tackifier was added in Example 32. In Example 34, a photopolymerization initiator and a polymerizable macromonomer were added. Tables 5-7 show the concentration and mass ratio of each component in the silver-containing nanowire compositions of Examples 2-35. Regarding the coating to the substrate, in Examples 33 and 34, the silver nanowire composition was diluted with ethanol so that the silver nanowire content was 0.2% by mass, while the other examples were diluted with pure water. The silver nanowire content was 0.2 mass %. For the silver-containing nanowire composition of Example 34, after drying the PET substrate...
