<P>PROBLEM TO BE SOLVED: To provide an interlayer for laminated glass capable of giving a laminated glass having excellent heat-shielding property and suppressing generation of bubbles and growth of bubbles. <P>SOLUTION: When the interlayer 21A for laminated glass has a single-layer structure, the interlayer is provided with a first layer 21 containing a thermoplastic resin, a plasticizer and an infrared absorber. When the interlayer 1 has a laminated structure having two or more layers, the interlayer is provided with first and second layers 2, 3 containing a thermoplastic resin and a plasticizer, and the first layer 2 or the second layer 3 contains the infrared absorber. The ratio of a high-molecular weight component having an absolute molecular weight of ≥1,000,000 in the thermoplastic resin of the first layer 2, 21 is ≥7.4% or the ratio of the high-molecular weight component having a polystyrene-reduced molecular weight of ≥1,000,000 in the thermoplastic resin of the first layer 2, 21 is ≥9%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
