An ethylene-vinyl alcohol copolymer composition contains: (A) an ethylene-vinyl alcohol copolymer including two or more types of ethylene-vinyl alcohol copolymers having different ethylene structural unit contents; and (B) an iron compound; wherein the iron compound (B) is present in an amount of 0.01 to 5 ppm on a metal basis based on the weight of the ethylene-vinyl alcohol copolymer composition. The ethylene-vinyl alcohol copolymer composition is substantially free from coloration and excellent in heat stability.

A multi-layer packaging film structure is disclosed. This packaging film structure includes a barrier web made up of a barrier web core layer, a barrier web skin layer, and a packaging sealant layer. Each of the aforementioned film layers is biodegradable and/or compostable. At least one of the film layers is made up of at least 1 weight percent of poly(3-hydroxypropionate). The packaging film structure may also include a print web or a paperboard substrate.

A film for laminating glass includes a polyvinyl acetal, a plasticizer, inorganic particles, and a trioxane-based compound.

Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. Polyurethane primer coatings and polyurethane top-coatings are applied to the thermoplastic polyurethane cover. Different coating methods can be used. Isocyanate-rich and polyol-rich polyurethane coatings can be applied. In one embodiment, the golf ball can be treated with a multi-functional isocyanate prior to applying the coatings. The polyurethane cover composition and surface coatings can further include catalysts, ultraviolet (UV)—light stabilizers, and other additives. Heat is used to cure the coatings. The coating methods have many benefits and the finished balls have good physical properties.

Provided is an interlayer film for laminated glass, having a dark color part with uniform parallel light transmittance in a shading region, and capable of suppressing color unevenness in the shading region. An interlayer film for laminated glass according to the present invention has one end, and the other on an opposite side of the one end, the other end has a thickness larger than a thickness of the one end, and when the interlayer film is arranged between two sheets of clear glass conforming to JIS R3202:1996 to obtain a laminated glass X, and a specific measurement of parallel light transmittance is conducted for the laminated glass X obtained, the interlayer film has a gradation part in which a parallel light transmittance continuously reduces from the one end side to the other end side, and an absolute value of a variation rate in the parallel light transmittance is more than 0.3%/mm; a transparent part located closer to the one end side than the gradation part and having a parallel light transmittance of 60% or more; and a dark color part located closer to the other end side than the gradation part and including one or more points A having an absolute value of a variation rate in the parallel light transmittance of 0.3%/mm or less.

An interlayer film for laminated glass of the present invention is an interlayer film for laminated glass, comprising one or two or more resin layers, and comprising a first resin layer comprising a resin and a light diffusion particle, in which any resin layer in the interlayer film for laminated glass comprises a colorant.
