Intermediate film for laminated glass, and laminated glass

Abstract

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.

1 - 6 . (canceled) 
     
     
         7 . An interlayer film for laminated glass, comprising:
 a light-emitting layer containing 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.   
     
     
         8 . The interlayer film for laminated glass according to  claim 7 ,
 wherein the lanthanoid complex is in the form of particles.   
     
     
         9 . The interlayer film for laminated glass according to  claim 8 ,
 wherein the upper limit of the average particle size of particle is 1 μm.   
     
     
         10 . The interlayer film for laminated glass according to  claim 7 ,
 wherein the lanthanoid complex is terbium.   
     
     
         11 . A laminated glass comprising:
 two transparent plates; and   the interlayer film for laminated glass according to  claim 7  interposed between the transparent plates.
