Patent number: 11981835Abstract: An interlayer filling material for a touch panel which is used for filling an interlayer space between a touch panel and another component or an interlayer space between transparent conductive films included in the touch panel in production of a personal digital assistant, which is excellent in followability to steps of a decorative printing portion or wiring upon filling of an interlayer space (lamination) and also excellent in defoaming properties to release air bubbles entrapped during filling of an interlayer space (lamination) or air bubbles left near the steps, which is less likely to be whitened and less likely to deteriorate an ITO film even under a high-temperature and high-humidity environment. The present invention also aims to provide a laminate produced using the interlayer filling material for a touch panel. The interlayer filling material includes: a polyvinyl acetal; a plasticizer; and an organic acid.Type: GrantFiled: March 2, 2022Date of Patent: May 14, 2024Assignee: SEKISUI CHEMICAL CO., LTD.Inventors: Juichi Fukatani, Ryousuke Ebina, Takazumi Okabayashi
