MULTILAYER MATERIAL, SEALING MATERIAL FOR SOLAR CELL, INTERLAYER FOR SAFETY (LAMINATED) GLASS, SOLAR CELL MODULE, AND SAFETY (LAMINATED) GLASS

摘要

Disclosed is a multilayer material which comprises an (A) layer that contains a silane coupling agent and an ethylene-based zinc ionomer and a (B) layer that contains an ethylene-based magnesium ionomer and/or an ethylene-based sodium ionomer. The multilayer material is suitable for use as a sealing material for a solar cell or an interlayer for safety (laminated) glass. It is preferable that the multilayer material contains at least two (A) layers and at least one (B) layer and has a multilevel structure wherein a (B) layer is interposed between two (A) layers.
