The present invention provides a pressure-sensitive adhesive composition, including: an acrylic copolymer and a crosslinking agent. The acrylic copolymer is a reaction product of a mixture of the following monomers: a first alkyl (meth)acrylate, an alkyl group in the first alkyl (meth)acrylate having at least 6 carbon atoms; a second alkyl (meth)acrylate, an alkyl group in the second alkyl (meth)acrylate having 1 to 5 carbon atoms; and a vinyl carboxylic acid, the weight ratio of the vinyl carboxylic acid to the mixture being 4% to 5%. The crosslinking agent is an organometallic chelating agent. The weight ratio of the organometallic chelating agent to the mixture is 0.05% to 0.25%. The pressure-sensitive adhesive composition does not contain an effective amount of a tackifier. The present invention further provides a pressure-sensitive adhesive solution, a pressure-sensitive adhesive tape, and a method for preparing the same. The pressure-sensitive adhesive of the present invention is a removable pressure-sensitive adhesive, and is applicable in hot weather and cold weather, and the adhesiveness of the pressure-sensitive adhesive does not decrease over time.

A pressure-sensitive adhesive sheet includes a resin film as a substrate and a pressure-sensitive adhesive layer provided on a first face of the substrate. In the pressure-sensitive adhesive sheet, a second face of the substrate is a release face, and the second face has a slip resistance value of 3.5 N or more. The pressure-sensitive adhesive sheet has a high-speed peel strength of 4.5 N/20 mm or higher, which is measured under conditions of a tensile speed of 30 m/min after 30 minutes of application to a stainless steel plate, and it has a difference between the maximum and minimum values of a self-backside adhesive strength of 1.5 N/20 mm or lower, which is measured under a condition of a tensile speed of 30 m/min.

A device includes a flexible substrate having a length and width greater than a depth of the substrate. A photocatalytic titanium dioxide or silver photocatalytic titanium dioxide coating is supported by the substrate on a first surface defined by the length and width of the substrate. An adhesive is disposed on a second surface of the substrate opposite the first surface of the substrate.

The present disclosure relates to ornamental indicia carrier and method of producing the same. In some embodiments, the ornamental indicia carrier comprises an ultraviolet light (“UV”) cured ink printed on a thin flexible film and combined with an adhesive layer. The ornamental indicia carrier is capable of enduring the conditions inside the mouth for an extended period of time and can be used in conjunction with a dental appliance.
