MULTILAYER STRUCTURE, METHOD FOR PRODUCING THE SAME, PACKAGING MATERIAL AND PRODUCT THAT INCLUDE THE SAME, PROTECTIVE SHEET FOR ELECTRONIC DEVICES, AND COATING LIQUID

摘要

The present invention relates to a multilayer structure including a base (X) and a layer (Y) stacked on the base (X), the layer (Y) containing the following at a specific ratio: a metal oxide (A); a phosphorus compound (B) containing a moiety capable of reacting with the metal oxide (A); and cations (Z) with an ionic charge (FZ) of 1 or more and 3 or less.

主权项

1. A multilayer structure comprising a base (X) and a layer (Y) stacked on the base (X), wherein
the layer (Y) comprises a metal oxide (A), a phosphorus compound (B), and cations (Z) with an ionic charge (FZ) of 1 or more and 3 or less, the phosphorus compound (B) comprises a compound containing a moiety capable of reacting with the metal oxide (A), the number of moles (NM) of metal atoms (M) constituting the metal oxide (A) and the number of moles (NP) of phosphorus atoms derived from the phosphorus compound (B) satisfy a relationship of 0.8≦NM/NP≦4.5 in the layer (Y), and the number of moles (NM), the number of moles (NZ) of the cations (Z), and the ionic charge (FZ) satisfy a relationship of 0.001≦FZ×NZ/NM≦0.60 in the layer (Y).
