摘要： The present invention has it for its object to provide an interlayer film for laminated glass and a laminated glass which shows a much decreased extent of blushing of the peripheral region thereof even when placed in a high-humidity atmosphere, without compromise in those fundamental performance characteristics which are required of laminated glass, such as transparency, weather resistance, adhesion and penetration resistance. The present invention is related to an interlayer film for laminated glass comprising a plasticized poly(vinyl acetal) resin and having the haze after 24 hours of immersion is not more than 50% when said interlayer film with a thickness of 0.3 to 0.8 mm is immersed in water at 23° C.
