A tie layer film, comprising an admixture of polyvinyl alcohol and a water dispersible polyester, for bonding a support film to a topcoat layer. The preferred tie layer comprises a sulfopolyester, preferably including terephthalate groups or isophthalate groups. Most preferred are sulfopolyesters produced from ingredients comprising monomers selected from the group consisting of dimethyl 5-sodiosulfoisophthalate, dimethyl terephthalate, dimethyl isophthalate, ethylene glycol, and polycaprolactone diol. Alternatively the support film may be a layered film. In a preferred embodiment, the topcoat layer is formed from the same PVA material as the tie layer and the support film includes at least a portion of the same sulfopolyester as the tie layer. The tie layer is capable of maintaining the bond between the support film and the topcoat layer when heat stretched to a stretch ratio in the range of 2 times to 10 times its original dimension.

Adhesive constructions include a mammalian skin surface and an adhesive article in contact with the mammalian skin. The adhesive article includes a substrate and an adhesive layer. The adhesive layer in contact with the mammalian skin is a microstructured surface with channels. At least one channel extends to at least one boundary of the adhesive layer. The microstructured surface is a permanently microstructured surface, such that the channels in the surface of the adhesive layer permit transport of fluid.

An optical stack includes an optical film () and an optical adhesive () disposed on the optical film. The optical adhesive has a major structured surface facing away from the optical film that includes a plurality of channels formed therein. The channels define a plurality of substantially flat land regions therebetween. The land regions include at least about 50% of a total surface area of the major structured surface. When the optical stack is placed on a support surface with the major structured surface of the optical adhesive contacting the support surface, the optical stack bonds to the support surface and may be removed from, or slidingly repositioned on, the support surface without damage to the optical adhesive or the support surface, and upon application of at least one of heat and pressure, the optical stack substantially permanently bonds to the support surface and the plurality of channels substantially disappear.

This disclosure describes a composition that includes a bulk diffuser that includes a film having a major surface; the film includes a polymer, and a scattering element. The scattering element includes a silicone bead having a mean particle diameter in a range of 2 micrometers (μm) to 9 μm. The linear density of the film is at least 5.1 W*μm, wherein the linear density equals the product of the mass fraction of the silicone bead (W) and film thickness in micrometers (μm). This disclosure further describes methods of making the film and the bulk diffuser and methods of using the film including, for example, as a bulk diffuser in a sign box.
