Provided are a seal tape and a secondary battery. The seal tape for adhering an electrode assembly includes a pressure-sensitive adhesive layer including a cured product of a pressure-sensitive adhesive composition including a polymer including a polar functional group-containing monomer as a polymerization unit, and is expanded in contact with an electrolyte solution to be detached from the electrode assembly, and therefore, isotropic volume expansion and contraction of the electrode assembly may be induced by repeated charging and discharging of a secondary battery and a disconnection phenomenon in which an electrode is disconnected may be prevented.

Pressure-sensitive adhesive composition

Provided are a seal tape and a secondary battery. The seal tape for adhering an electrode assembly includes a pressure-sensitive adhesive layer including a cured product of a pressure-sensitive adhesive composition including a polymer including a polar functional group-containing monomer as a polymerization unit, and is expanded in contact with an electrolyte solution to be detached from the electrode assembly, and therefore, isotropic volume expansion and contraction of the electrode assembly may be induced by repeated charge and discharge of a secondary battery and a disconnection phenomenon in which an electrode is disconnected may be prevented.

Seal tape

Provided are a base film, a laminate, and a method of forming a polarizing film. Particularly, a base film which may effectively form a polarizing film having a thickness of approximately 10, 8, 7, 6, or 5 &#x3bc;m or less and exhibiting excellent functions such as polarizing performance, a laminate, and a method of forming the same are provided. Therefore, a polarizing film may be formed by preventing tearing or curling during an elongation process, and easily elongating a polarizing material such as a polyvinylalcohol-based resin.

Laminate

The present invention relates to swelling tape for filling a gap and its use. The swelling tape is, for example, applied between gaps in which a fluid is present, thereby being deformed into a three-dimensional shape to fill the gap and fix an object separated by gaps as needed.

Swelling tape for filling gap

A swelling tape for filling a gap, a method of manufacturing the swelling tape for filling a gap, a method of filling a gap, an electrode assembly and a secondary battery are provided. For example, the swelling tape can be applied inside a gap in which a fluid exists so as to fill the gap by becoming a 3D form, and can be useful at anchoring a subject in which the gap is formed, as necessary.

The present application relates to a swelling tape and a method of filling a gap. The swelling tape is, for example, applied in gaps in which a fluid is present and deformed into a three-dimensional shape to fill the gaps and fix in place objects separated by gaps as needed.

A swelling tape for filling a gap and a method of filling a gap are provided. The swelling tape can be applied within the gap having a fluid to realize a 3D shape thereby filling the gap, and be used to fix a subject forming the gap as necessary.

There are provided a substrate film, a laminate, and method of manufacturing a polarizing film. The present application provides a substrate film capable of effectively manufacturing a polarizing film having a thickness of about 10 &#x3bc;m or less, about 8 &#x3bc;m or less, about 7 &#x3bc;m or less, about 6 &#x3bc;m or less, or about 5 &#x3bc;m or less and having an excellent function such as polarization performance, a laminate, and a method of manufacturing the same. According to the invention, it is possible to prevent tearing, curling, or the like from occurring in the elongation process and manufacture a polarizing film by easily elongating a polarization material such as a PVA-based resin.

Substrate film

Provided are a pressure-sensitive adhesive composition for a touch panel, a conductive film, a touch panel and a pressure-sensitive adhesive film. The exemplary pressure-sensitive adhesive composition for a touch panel, the conductive film or the pressure-sensitive adhesive film has excellent durability and optical properties such as transparency. In addition, such physical properties are stably maintained under severe conditions. Particularly, a pressure-sensitive adhesive layer is attached to a conductor thin film, and thus resistance change of the conductor thin film is effectively inhibited even when the conductor thin film is exposed to the severe conditions. Therefore, the pressure-sensitive adhesive composition may be effectively used to manufacture a touch panel.
