Provided is an adhesive layer-equipped transparent surface material that can easily be bonded to another surface material (a display panel, etc.) and that, when bonded to another surface material, is less likely to have voids left at the interface between the adhesive layer and another surface material. An adhesive layer-equipped transparent surface material 1 comprises an adhesive layer 14 formed on at least one surface of a protective plate 10 (a transparent surface material), wherein the adhesive layer 14 has a layer portion 18 spreading over the surface of the protective plate 10 and a barrier portion 20 surrounding the periphery of the layer portion 18; and the layer portion 18 has a shear modulus at 35 C. of from 0.5 to 100 kPa.

A method is presented for producing an optically transmissive layered structure for use as a display protector for electronic devices. The method comprises printing an ink pattern on a base layer, where said base layer is substantially optically transparent, and the base layer and ink are configured so that the ink reflects light with high incidence angle and transmits light with low incidence angle, when in use, thus displaying the pattern in the absence of light with high intensity and low incidence angle, the pattern becoming substantially undetectable otherwise.

Provided are a pressure-sensitive adhesive composition, a protective film, an optical device, and a display device. The pressure-sensitive adhesive composition may exhibit excellent storage stability, suitable low speed and high speed peel-off strengths after a crosslinking structure is formed, and have an excellent balance between them. Accordingly, the pressure-sensitive adhesive composition may exhibit an excellent protective effect when applied to a protective film, may be easily peeled in high speed peel-off and thus advantageous for a high speed process, and may exhibit an excellent antistatic property in the process.

A connector or adhesive assembly for joining adjacent ends of insulation tubing, comprising a layer of pressure-sensitive transfer adhesive material, said layer of pressure-sensitive transfer adhesive material capable of bonding to insulation tubing, whereby when said layer of pressure-sensitive transfer adhesive material is positioned between a first section of insulation tubing and a second section of insulation tubing, said layer of pressure-sensitive transfer adhesive material bonds to both the first section of insulation tubing and the second section of insulation tubing; and a disposable release liner member adapted to hold said layer of pressure-sensitive transfer adhesive material prior to positioning said layer of pressure-sensitive transfer adhesive material between the first section of insulation tubing and the second section of insulation tubing. Generally, the seam created when the first section of insulation tubing and the second section of insulation tubing are joined is covered with tape.

A repairing or reinforcement method includes applying, to concrete, a pressure-sensitive or bonding adhesive sheet containing a first pressure-sensitive or bonding adhesive layer; and curing the first adhesive layer such that a first surface of the first adhesive layer is bonded to the concrete. The first adhesive layer contains an acrylic resin having a glass transition temperature of 15 C. or below, a liquid epoxy resin, a solid epoxy resin, and a curing agent.

A pressure-sensitive adhesive composition, a protective film, an optical element and a display device are provided. The pressure-sensitive adhesive composition has excellent storage stability, exhibits proper low-speed and high-speed peel strengths after formation of a cross-linked structure, and also has an excellent balance between the low-speed and high-speed peel strengths. Therefore, when the pressure-sensitive adhesive composition is applied to a protective film, the pressure-sensitive adhesive composition can have an excellent protective effect, and can also be advantageous to perform a high-speed process since the pressure-sensitive adhesive composition is easily peeled during a high-speed peeling process. In the high-speed peeling process, the pressure-sensitive adhesive composition can exhibit excellent antistatic characteristics.

A label assembly and method of using the same to label articles durably, yet removably. In one embodiment, the method includes providing an image removing laminate. The image removing laminate includes (i) a remover support, and (ii) a remover layer secured to the remover support, the remover layer, upon being activated by at least one of heat and light, being bondable to an ink image on a garment in such a way that the bonding between the remover layer and the ink image is stronger than the bonding between the ink image and the garment. The method then includes bonding the remover layer of the image removing laminate to the ink image on the garment and, then, detaching the ink image from the garment by separating the image removing laminate away from the garment.

A polymer sheet includes a polyurethane core. The polyurethane core has a first major surface and a second major surface opposite the first major surface. The polymer sheet can have at least one functional layer overlying a major surface. The polymer sheet has a thickness t.sub.PS. The polyurethane core has a thickness t.sub.PC. In embodiments t.sub.PC can be at least 0.3 t.sub.PS. The polyurethane core can have at least one of the following property: (i) a Scratch Resistance Rating, as further described herein, of not greater than about 10 wt %, (ii) an elongation at break of at least 200%, (iii) a tensile strength at break of at least 0.3 MPa, (iv) a loss of tensile strength of not greater than about 30% when exposed to UV light according to standard SAE J1960 (Rev. August 2003).
The polymer sheet can be used for gaskets or bonding tapes.
