A polarizing plate includes a polarizer and a protective film stacked on at least one surface of the polarizer, and the polarizer includes a hydrophobic polyvinyl alcohol resin, the polarizer has a surface roughness (Ra) of about 10 nm or less on a surface thereof facing the protective film, and the polarizing plate has a maximum metal ion-infiltration length of about 400 μm or less between the polarizer and the protective film when metal powder-containing pastes are deposited on a surface of the polarizing plate in a thickness direction thereof and left at 60° C. and 95% relative humidity (RH) for 240 hours.

The present invention contemplates a method for forming a composite structure including a plurality of rigid layers and one or more reformable epoxy resin layers. The resulting composite is molded to form a non-planar composite structure.

A paper based overlay is provided. The overlay has a paper impregnated with a resin composition having an acrylic resin having a glass transition temperature in a range of from about −20° C. to about 40° C. and a resin content from about 15 to about 35 wt. % based on the weight of the overlay. The acrylic composition may include wax in the amount of about 0.005 to about 3.5 wt. % based on the weight of the resin composition. A method of producing the overlay is also provided. The overlay is highly water and abrasion resistant with low volatile content.

A method is described for debonding a bonded article. The bonded article comprises at least two components which are bonded to one another by means of a polyurethane adhesive selected from aqueous polyurethane dispersion adhesives and polyurethane hotmelt adhesives. At least one of the components is a thermoplastic polyurethane. The components are debonded by treatment with an aqueous surfactant composition at elevated temperatures.

A method for manufacturing a polyester film for embossing that is made from a recycled polyester material. A part of the recycled polyester material is physically reproduced to obtain physically regenerated polyester chips. The physically regenerated polyester chips include physically regenerated regular polyester chips. Another part of the recycled polyester material is chemically reproduced to obtain chemically regenerated polyester chips. The chemically regenerated polyester chips include chemically regenerated regular polyester chips and chemically regenerated electrostatic pinning polyester chips. The physically regenerated polyester chips and the chemically regenerated polyester chips are mixed to form a base material. The base material is used to form a base layer that having a main component of regenerated polyethylene terephthalate. A surface coating layer is formed onto the base layer. A material of the surface coating layer includes a main resin, fillers, and melamine.

Systems and methods are disclosed for a multi-layered sound absorption structure. The multi-layered sound absorption structure may include a form material, an acoustic material disposed on a surface of the form material, and a construction material disposed on the acoustic material. The acoustic material may couple to the construction material during curing of the construction material. After the construction material is cured, the form material may be removed exposing a least a portion of the acoustic material.

Disclosed embodiments generally relate to a transaction card with a fabric inlay. The transaction card may include a housing component having a first housing surface opposite a second housing surface and an inlay component having a first inlay surface opposite a second inlay surface. The inlay and housing may be joined along the second inlay surface and the first housing surface. In addition, the first inlay surface may include a fabric material and a backer layer configured to support the fabric material of the first inlay surface.

For the purpose of providing a skin material that is easily bonded to a base material, an interior material including the skin material, and a method for manufacturing the interior material, a skin material includes a base cloth layer and a design layer. The base cloth layer includes a surface fabric and a back fabric, and a binding yarn that binds the surface fabric and the back fabric. The binding yarn is erected between the surface fabric and the back fabric to form a void inside the base cloth layer. An embossed pattern is formed in a concave shape on the skin material from the design layer side. A thin portion is formed in a band shape in a peripheral edge portion of the skin material. The skin material is bonded to the base material to obtain an interior material.

Provided are a two-component curable adhesive which can be aged at room temperature and has favorable adhesiveness to various base materials, a laminate in which the adhesiveness between a base material and an adhesive is excellent even when aged at room temperature, and a packaging material including the laminate. The two-component curable adhesive includes a polyisocyanate composition (X) including a polyisocyanate compound (A) and a polyol composition (Y) including a polyol (B), in which a viscosity of the polyol composition at 50° C. is 20 mPa.Math.s or more and 180 mPa.Math.s or less.
