The purpose of the present invention is to provide a transfer sheet capable of providing hard coat properties and excellent weather resistance to a resin molded article such as organic glass. The transfer sheet has, in order, a base material film for mold release, a hard coat layer, a primer layer, and an adhesive layer. The weather resistance and adhesiveness of the hard coat layer and the primer layer are improved and hard coat properties and excellent weather resistance can be provided to a resin molded article being the transfer object, as a result of: the hard coat layer being formed from a cured product of a resin composition including a curable resin; and the primer layer being formed from a binder resin including a polyurethane having a mass-average molecular weight of 40,000-100,000 and including 1-30% by mass of an acrylic component.

Described herein is a protection film comprising a polyolefin carrier material, a precoating of the polyolefin carrier material with a primer selected from polyurethane dispersions and a pressure-sensitive adhesive layer of a radiation-crosslinked hotmelt adhesive. A process for producing such protection films is also described.

Articles and laminates include a substrate with a first polyester surface and a second polyester surface, a crosslinked polyurethane-based primer coated on at least the first polyester surface, and an optically clear heat activated adhesive adjacent to the crosslinked polyurethane-based primer. The articles and laminates are prepared by applying a polyurethane-based dispersion and a crosslinker on at least one polyester surface, drying the applied coating, heating while stretching the substrate and the coating to form a crosslinked primer layer on the stretched polyester surface, and applying an optically clear heat activated adhesive onto the crosslinked primer layer.

A method for surface preparation of composite substrates prior to adhesive bonding. A curable surface treatment layer containing blocked isocyanate compounds is applied onto a curable composite substrate, followed by co-curing. The surface treatment layer may be a resin layer without fibers or a removal peel ply composed of resin-impregnated fabric. After surface preparation, the composite substrate is provided with a chemically-active, bondable surface that can be adhesively bonded to another composite substrate to form a covalently-bonded structure.

A polyurethane based adhesive containing one polyol compound derived from caprolactone monomer having a number average molecular weight between 200 and 1000 combined with a polyisocyanate compound. The functionality of the polycaprolactone polyol is between 1 and 4. Other aspects include a polarizing layered structure, a polarized lens and a method for manufacturing same all of which include the polyurethane based adhesive. The adhesive avoids delamination and is useful in optical applications where it will be in contact with water, for example during surfacing or edging process.

The present invention relates to a flexible film, more specifically, to a flexible film that not only exhibits high hardness, but also has excellent flexibility. According to the flexible film of the present invention, flexibility, bendability, high hardness, scratch resistance, and high transparency are exhibited, and there is no concern for damage of the film even when bended repeatedly or folded for a long time, and thus, it may be usefully applied for the front panels, display parts of bendable, flexible, rollable, or foldable mobile devices, display devices, various instrument panels, and the like.

[Object] An object of the present invention is to provide an easily peelable adhesive tape that has a good peel adhesive strength when attached to an adherend and that can be easily peeled after being irradiated with active energy rays. [Solution] The present invention is directed to an easily peelable adhesive tape that has, on at least one surface of a base material, an active energy ray-curable layer having a storage modulus (G.sub.a25) of less than 1.010.sup.6 Pa as measured at a temperature of 25 C. and a frequency of 1.0 Hz and has an adhesive layer on the surface side of the active energy ray-curable layer.

Two part sole structures are provided having a first foam component containing a polyolefin resin with a polyurethane resin component adhered to a surface of the first foam component. For example, in some aspects, a sole structure or a portion thereof is provided having a first sole component containing a foam composition and a second sole component adhered to a surface of the first sole component, where the second sole component includes a polyurethane resin. The second sole component is in some aspects printed or extruded onto the surface of the foam. In particular, midsoles including the foams and having an outsole component on the ground facing portion are provided for use in an article of footwear. Methods of making the sole structures are provided, as well as methods of making an article of footwear including one of the sole structures.

Provided are: a surface-treated metal sheet that is useful when integrating a molded plastic (resin) article and a metal sheet during injection molding; and a metal sheet-resin composite molded article in which the metal sheet and a resin molded article are integrated. The surface-treated metal sheet consists of a laminate having a metal substrate, a chemical conversion coating film and an adhesive layer in order, and is characterized in that the chemical conversion coating film contains colloidal silica and a thermosetting resin.
