Interlayer films for laminated glazing containing silica with specific refractive index |
摘要 |
Interlayer films useful for laminated glass contain a polyvinyl acetal (A), at least on plasticizer (B), fumed silica (C) and at least one basic compound (D), wherein the difference of refractive index between fumed silica (C) and plasticized polyvinyl acetal (A+B) is 0.015 or less, and the weight ratio of C/(A+B) is 2.7-60/100.
