Abstract
Resin compositions, layers, and interlayers comprising two or more poly(vinyl acetal) resins and at least one blending agent or haze reducing agent are provided. Such compositions, layers, and interlayers exhibit enhanced optical properties while retaining other properties, such as impact resistance and acoustic performance.
Claims7
An interlayer comprising:
- a resin layer comprising—
- a first poly(vinyl acetal) resin;
- a second poly(vinyl acetal) resin, wherein said second poly(vinyl acetal) resin is present in said resin layer in an amount of at least 0.3 weight percent, based on the combined weight of said first and said second poly(vinyl acetal) resins;
- and
- a haze reducing agent,
- wherein said resin layer has an HLD haze value that is at least 5 percent lower than the HLD haze value of an identical resin layer that does not include said haze reducing agent.
