The present invention provides an anti-fouling pressure-sensitive adhesive sheet and anti-fouling treatment method capable of preventing peeling from overlapping portions when adjacent anti-fouling pressure-sensitive adhesive sheets are attached by allowing end portions thereof to overlap each other. The anti-fouling pressure-sensitive adhesive sheet of the present invention includes a base material layer; a pressure-sensitive adhesive layer provided on one side of the base material layer; and an anti-fouling layer provided on another side of the base material layer, wherein the anti-fouling pressure-sensitive adhesive sheet has, at an end portion thereof, a bonding margin including parts of the base material layer and the pressure-sensitive adhesive layer, the parts extending beyond the anti-fouling layer.

Heat de-bondable adhesive articles include a heat-shrinkable optical substrate with optically clear adhesive disposed on the two major surfaces of the heat-shrinkable substrate. Optical articles can be prepared by disposing the heat de-bondable adhesive articles between two optical substrates. Other optical articles can be prepared by disposing an optically clear adhesive layer and a heat-shrinkable optical substrate on an optical substrate.

The shrink film has a multilayer structure including layers A, B, C, B, and A disposed in this sequence without the mediation of another layer. The layers A include 50 percent by weight or more of a polystyrene resin. The layers B include 20 to 80 percent by weight of a polystyrene resin and 20 to 80 percent by weight of a polypropylene resin. The layer C includes 50 percent by weight or more of a polypropylene resin. The polystyrene resin in the layer A includes a styrenic-monomer-derived constitutional unit of 85 to 95 percent by weight and a diene-derived constitutional unit of 5 to 15 percent by weight. The polystyrene resin in the layer B includes a styrenic-monomer-derived constitutional unit of 50 to 80 percent by weight and a diene-derived constitutional unit of 20 percent by weight to less than 50 percent by weight.
摘要:
A device or method to prevent penetration of oil and petroleum products while allowing high water flow rate is provided. Such device or method is beneficial in controlling the contamination of surrounding soil from accidental leak of hydrocarbons such as oil and other petroleum products from equipment or storage vessels containing such materials. The containment systems equipped with these devices will allow the rain water to flow through while providing barrier to oil and petroleum products.

摘要:
The invention described herein is directed towards spin-on carbon materials comprising polyamic acid compositions and a crosslinker in a solvent system. The materials are useful in trilayer photolithography processes. Films made with the inventive compositions are not soluble in solvents commonly used in lithographic materials, such as, but not limited to PGME, PGMEA, and cyclohexanone. However, the films can be dissolved in developers commonly used in photolithography. In one embodiment, the films can be heated at high temperatures to improve the thermal stability for high temperature processing. Regardless of the embodiment, the material can be applied to a flat/planar or patterned surface. Advantageously, the material exhibits a wiggling resistance during pattern transfer to silicon substrate using fluorocarbon etch.
