COMPOSITE STRUCTURE, PACKAGING MATERIAL AND MOLDED ARTICLE EACH PRODUCED USING SAME, PROCESS FOR PRODUCTION OF COMPOSITE STRUCTURE, AND COATING SOLUTION

摘要

The composite structural material of the present invention includes a base (X) and a layer (Y) stacked on the base (X). The layer (Y) includes a reaction product (R) of a metal oxide (A) and a phosphorus compound (B). In the infrared absorption spectrum of the layer (Y) in the range of 800 to 1400 cm -1 , the wave number (n 1 ) at which the infrared absorption reaches maximum is in the range of 1080 to 1130 cm -1 .
