Resin compositions, layers, and interlayers comprising a poly(vinyl acetal) resin that includes residues of an aldehyde other than n-butyraldehyde are provided. Such compositions, layers, and interlayers can exhibit enhanced or optimized properties and lower VOC levels as compared to those formulated with comparable poly(vinyl n-butyral) resins.
