Abstract
Official abstract text for this publication.
The present invention aims to provide an interlayer film for laminated glass capable of displaying images with a high luminous intensity when irradiated with a light beam and having excellent durability, and a laminated glass including the interlayer film for laminated glass. The present invention relates to an interlayer film for laminated glass, including a light-emitting layer that contains a polyvinyl acetal resin and a lanthanoid complex as light-emitting particles, the light-emitting layer containing not more than 100 ppm in total of a nitric acid-derived component and a carbonate component.
First claim
