    Abstract: The present invention provides a pressure-sensitive adhesive (PSA) sheet which is formed using a non-toluene solvent-based acrylic PSA composition, and which minimizes corrosion of metals not in contact with the PSA sheet. PSA sheet 1 has PSA layers 21, 22 formed from a solvent-based PSA composition. The PSA composition includes, within an organic solvent that is substantially free of toluene substances, an acrylic polymer synthesized in presence of a sulfur-containing chain transfer agent. Moreover, in a gas generation test whereby PSA sheet 1 is heated at 85° C. for one hour, the emission of sulfur-containing gas is 0.043 μg or less per 1 cm2 surface area of PSA sheet 1, when converted to SO42−.

    Abstract: The invention relates to a polyacrylate which as a result of a polymerization process has a broad, bimodal molecular weight distribution. These acrylate pressure-sensitive adhesives are preferably processed from the melt. The low molecular weight fraction lowers the flow viscosity, while the high molecular weight fraction results in the achievement of a high shear strength, following appropriate crosslinking, for the acrylate pressure-sensitive adhesive.

    Abstract: A double-sided pressure-sensitive adhesive (PSA) sheet having a plastic film as a substrate is provided, with the property of corroding a metal not in contact therewith being suppressed. This PSA sheet has a PSA layer that uses a water-dispersed acrylic PSA composition on each side of the plastic film substrate. The PSA composition contains a water-dispersed acrylic polymer synthesized using a sulfur-containing chain transfer agent. The PSA sheet has the emission of sulfur-containing gas of 0.043 μg or less per 1 cm2 surface area of the PSA sheet, when converted to SO42−, in a gas generation test under which the PSA sheet is heated at 85° C. for one hour.
