Provided are adhesives containing a phenoxy resin grafted with methyl methacrylate (MMA) and/or methacrylic acid (MAA), and including a uretdione or a silane. The adhesive compositions are completely or substantially absent free isocyanate. The grafted phenoxy resin forms crosslinking which allows the adhesive to chemisorb to a metal surface, diffuse and entangle in a urethane elastomer and/or provide crossbridging and/or crosslinking across an interface of the adhesive and a cast urethane. Methods of adhering a castable urethane to a substrate, using the provided adhesives, are also provided.

The present invention discloses a composite film with clear texture and high quality and a preparation process thereof, relating to the technical field of composite films. The composite film with clear texture and high quality comprising a texture layer, a protective coating layer, a printed coating layer, an adhesive layer and a first substrate layer sequentially laminated from a top layer to a bottom layer, wherein the protective coating layer is provided on a surface of the texture layer facing the first substrate layer, the printed coating layer is provided on a surface of the protective coating layer facing the first substrate layer, and the texture layer is connected to the first substrate layer. The composite film with clear texture and high quality can realize multi-texture alignment printing by combining texture layers with printing, allowing one upper to have a variety of different textures and a variety of different colors.
