    Abstract: The present invention relates to a pressure sensitive adhesive sheet including a pressure sensitive adhesive layer on at least one surface of a base material, wherein the pressure sensitive adhesive layer is made of a two-layer structure of a first pressure sensitive adhesive layer and a second pressure sensitive adhesive layer in this order from the side of the base material; a first pressure sensitive adhesive constituting the first pressure sensitive adhesive layer has a loss tangent (tan δ) value at 0° C. of 0.25 or more and a storage elastic modulus value at 0° C. of from 0.01 to 0.80 MPa; and a resin component contained in a second pressure sensitive adhesive constituting the second pressure sensitive adhesive layer contains from 10 to 100 t by mass of an acrylic copolymer having a crosslinkable functional group. The pressure sensitive adhesive sheet according to the present invention exhibits an excellent adhesive strength even when the pressure sensitive adhesive layer is reduced in thickness.

    Abstract: The present system is a waterborne coating system comprising a two-part aqueous polyurethane coating which provides for building solvent based equivalent film thickness without foaming or gassing while retaining properties of little or no volatile organic compound (VOC) or hazardous air pollutant (HAPs) emission. A blend of various acrylic copolomers neutralized in water based emulsion and combined with an emulsified polyester polyol provides the resin system allowing adhesion to a various number of substrates. In at least one embodiment, the acrylic polyol is an acrylic copolymer having the hydrophilizing groups and isocyanate-reactive functionality incorporated into the polymer via appropriate monomer selection or subsequent modification.
