Title (EN) NANO-SILVER WIRE INK
(FR) ENCRE À BASE DE NANOFIL D’ARGENT
(JA) 銀ナノワイヤインク
Abstract:
(EN) [Problem] To provide nano-silver wire ink capable of stably suppressing degradation of the conductivity of a nano-silver wire conductive layer caused by the application of a coating solution for forming a transparent protective layer. [Solution] This nano-silver wire ink has, in an aqueous solvent, a water-soluble cellulose ether having a methoxy group and a nano-silver wire, wherein the mass percentage of the methoxy group in the water-soluble cellulose ether is 16.0-25.0%. HPMC, in which the mass percentage of a hydroxypropoxy group is 10.0% or less, or HEMC, in which the mass percentage of a hydroxyethoxy group is 12.0% or less, may be a particularly appropriate example of the water-soluble cellulose ether.
(FR) Le problème décrit par la présente invention est de préparer une encre à base de nanofil d’argent capable de supprimer de manière stable la dégradation de la conductivité d’une couche conductrice de nanofil d’argent provoquée par l’application d’une solution de revêtement afin de former une couche protectrice transparente. La solution selon l’invention porte sur cette encre à nanofil d’argent présentant, dans un solvant aqueux, un éther de cellulose soluble dans l’eau présentant un groupe méthoxy et un nanofil d’argent, le pourcentage en masse du groupe méthoxy dans l’éther de cellulose soluble dans l’eau étant de 16,0 à 25,0 %. Le HPMC, dans lequel le pourcentage en masse d’un groupe hydroxypropoxy est de 10,0 % ou moins, ou le HEMC, dans lequel le pourcentage en masse d’un groupe hydroxyéthoxy est de 12,0 % ou moins, peut être un exemple particulièrement approprié d’éther de cellulose soluble dans l’eau.
(JA) 【課題】透明保護層形成用の塗工液塗布に起因する銀ナノワイヤ導電層の導電性低下を安定して抑止することができる銀ナノワイヤインクを提供する。 【解決手段】水系溶媒中に、メトキシ基を持つ水溶性セルロースエーテル、および銀ナノワイヤを有し、前記水溶性セルロースエーテルに占めるメトキシ基の質量割合が16.0~25.0%である銀ナノワイヤインク。上記水溶性セルロースエーテルとして、ヒドロキシプロポキシ基の質量割合が10.0%以下であるHPMCや、ヒドロキシエトキシ基の質量割合が12.0%以下であるHEMCが、特に好適な例として挙げられる。
