摘要：Provided is an interlayer for laminated glass which increases sound-insulatingproperties in a high frequency area in a laminate glass over a wide temperature range. An
interlayer film for laminated glass of the present invention includes first, second, andthird layers, wherein when a cloud point C1 is measured by using a first liquid containing100 parts by weight of a first plasticizer and 8 parts by weight of a first polyvinyl acetalresin contained in the first layer, a cloud point C2 is measured by using a second liquidcontaining 100 parts by weight of a second plasticizer and 8 parts by weight of a secondpolyvinyl acetal resin contained in the second layer, and a cloud point C3 is measured byusing a third liquid containing 100 parts by weight of a third plasticizer and 8 parts byweight of a third polyvinyl acetal resin contained in the third layer, the cloud point C1 is10° C. or lower; the cloud point C2 is higher than the cloud point C1 by at least 5° C.; andthe cloud point C3 is higher than the cloud point C1 by at least 50° C. and higher than thecloud point C2.
