摘要： The present invention aims to provide 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, is excellent in followability to steps, and enables production of a touch panel laminate that is less likely to suffer cracks or breakage in a surface protection panel or a glass substrate. The present invention also aims to provide a touch panel laminate produced using the interlayer filling material for a touch panel. The present invention relates to an interlayer filling material for a touch panel used for filling an interlayer space between a touch panel and another component, or at least one of interlayer spaces included in the touch panel between transparent conductive films, between a glass sheet and one of the transparent conductive films, between a glass sheet and another glass sheet, between a glass sheet and a polarizing film, between a substrate and a glass sheet, between a substrate and one of the transparent conductive films, and between a substrate and a polarizing film, the interlayer filling material containing: a polyvinyl acetal; and a plasticizer, the interlayer filling material having a storage modulus G′ (20° C.) at 20° C. of 1×107 Pa or higher and a storage modulus G′ (70° C.) at 70° C. of 3×106 Pa or lower.

摘要： The present invention aims to provide a polyvinyl acetal resin composition that is moldable by an extrusion method and capable of exhibiting excellent heat resistance after molding, an adhesive sheet containing the polyvinyl acetal resin composition, and a method for producing the adhesive sheet. The present invention relates to a polyvinyl acetal resin composition including: a polyvinyl acetal; a reactive diluent; and a photopolymerization initiator, the polyvinyl acetal resin composition having a storage modulus G′ at 200° C. before irradiation with light of 8×104 Pa or lower and a storage modulus G′ at 200° C. after irradiation with light of 8×103 Pa or higher, with the storage modulus G′ at 200° C. after irradiation with light being higher than the storage modulus G′ at 200° C. before irradiation with light.
