摘要：
Multilayered interlayers having good acoustic properties comprising a stiff skin layer(s) and a soft core layer(s) are disclosed. The multilayered interlayers comprise: a first polymer layer (skin layer) comprising plasticized poly(vinyl acetal) resin; a second polymer layer (core layer) comprising plasticized poly(vinyl acetal) resin; wherein at least one plasticizer is a high refractive index plasticizer. The multilayered interlayers have low mottle and resist mottle formation.
