Disclosed herein are various embodiments of a protective packaging system suitable for use with a prefinished building article. The protective packaging system generally is designed to reduce shrink back of the flexible substrate after tension is applied. The protective packaging system generally comprises at least one outer layer, at least one core layer and at least one adhesive layer. One or more layers of the protective packaging system may include a roughening agent such that the flexible substrate will not “gloss” or burnish a coating on a prefinished building article. The protective packaging system may also include one or more biocides.

Adhesive compositions comprising an aqueous dispersion of an acrylic polymer are disclosed, with such compositions having particular applicability in additive manufacturing processes, such as three-dimensional (3D) printing, including Fused Filament Fabrication (FFF). In particular, the compositions address drawbacks associated with an improper degree of adhesion between a thermoplastic build material and build plate, which decrease the quality of printed objects. In representative aqueous dispersions, the solids content of at least about 5 wt. % and also most about 95 wt. % of the acrylic polymer is solubilized, with the balance of this polymer comprising dispersed solid particles.

Provided is a PSA sheet capable of suitably preventing bubble formation caused by outgassing. This invention provides a PSA sheet comprising a PSA layer that forms an adhesive face. In an aging test where the adhesive face is press-bonded to a glass plate and stored at 50° C. for 24 hours, the PSA sheet has at least 5% post-aging non-bonding area Sa, with Sa defined as the ratio of all areas non-bonding to the glass plate relative to the total area of the adhesive face. The non-bonding areas have parts linearly extending along the adhesive face.

Provided are buffered adhesive compositions comprising a high molecular weight non-neutralized polymeric acid and a high molecular weight partially neutralized polymeric acid and products such as wound dressings and ostomy skin barriers incorporating the compositions.

The present invention pertains to a one-side-protected polarizing film having a protective film or films on only one surface of a polarizer, wherein: the polarizer contains a polyvinyl alcohol-based resin, and is designed to have a single-body transmittance T and a polarization degree P representing optical properties satisfying the condition of the following formula: P>−(10.sup.0.929T−42.4−1)×100 (provided that T<42.3) or P≥99.9 (provided that T≥42.3), and the polarizer and a transparent resin layer have a thickness X (μm) and a thickness Y (μm), respectively, satisfying X≤12, Y≤15, and 0.15≤(Y/X)≤3. Even when the thin-type polarizer has prescribed optical properties, this one-side-protected polarizing film is capable of suppressing the occurrence of through cracks, nano-slit-induced defects and curling.
