<P>PROBLEM TO BE SOLVED: To provide a laminated glass interlayer, which enables sound insulation to be improved in high frequency ranges in laminated glass. <P>SOLUTION: The laminated glass interlayer 1 is provided with a first layer 2 containing a polyvinyl acetal resin and a plasticizer. The plasticizer contained in the first layer 2 contains a first plasticizer. The polyvinyl acetal resin and the first plasticizer contained in the first layer 2 have a clouding point, measured using a liquid in which 8 pts.wt. of the polyvinyl acetal resin have been dissolved in 100 pts.wt. of the first plasticizer, that is not more than 5°C. The laminated glass interlayer 1 has a single layer structure or a laminated structure with 2 or more layers. The laminated glass interlayer is provided with first and second laminated glass component members, and the interlayer 1, which is sandwiched between the first and second laminated glass component members. <P>COPYRIGHT: (C)2013,JPO&INPIT |
