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 as compared to those formulated with comparable poly(vinyl n-butyral) resins.

Disclosed is a textile-like in-mold sheet that is to be integrated with a resin molded body molded by injection of a molten resin by in-molding. The textile-like in-mold sheet includes at least a fiber sheet layer, a first adhesive layer, and a textile material layer, in this order from a surface that will serve as a side to be integrated with the resin molded body. Alternatively, the textile-like in-mold sheet includes at least a textile material layer and a temporary surface protection layer temporarily bonded to the textile material layer, in this order from the surface to be integrated with the resin molded body.

Disclosed herein is a textile-like in-mold sheet that is to be integrated with a resin molded body molded by injection of a molten resin by in-molding. The textile-like in-mold sheet includes a first surface that is to be integrated with the resin molded body, and a second surface that will serve as a back side of the first surface, such that the textile-like in-mold sheet contains at least a textile material layer and a temporary surface protection layer temporarily bonded to the textile material layer, in this order from the first surface toward the second surface.
