Embodiment

[0067] The present invention can be better understood by the following examples, which are provided for illustration and should not be construed as limiting the invention.

[0068]

[0069] Measurement of electrostatic voltage at peeling: Measured using a 718A static sensor available from 3M when an adhesive-coated protective tape is attached to the surface of a polarizing film for LCD and then peeled off at a rate of 300mm / minute The electrostatic voltage generated at this time.

[0070] Measurement of Surface Resistance and Decay Time: The surface resistance of the outermost layer of the protective tape and its adhesive-coated surface was measured using SRM110. In addition, the upper and lower parts of the film were connected to each other using a ground clamp, and then the decay time required for the voltage to drop from an initial applied amount of 1000 V to 100 V was measured using a Monroe CPM 288.

[0071] Measurement of contact angle: 10 points on a surface with a s...

Embodiment 1

[0093] A thermosetting antistatic solution with waterproof effect and antifouling effect was prepared, coated on one surface of a 36 m thick PET film to a thickness of 0.1 μm, and then dried at 80° C. for 2 minutes. Also, on the other surface of the film, an acrylic adhesive was coated to a thickness of 15 μm.

[0094] The surface resistance of the film was determined to be 10 7 Ω / μm. The film was cut into a size of 25 mm×100 mm, attached to the polarizing film, and then peeled off at a rate of 300 mm / minute. As a result, the electrostatic voltage generated was 100V, and the decay time after application of 1000V was 1.8 seconds, so fast decay was not achieved.

[0095] The contact angle was measured to be about 92 using a surface tensiometer. When the film was pressed with a finger, no fingerprints were observed on the surface.

[0096] Therefore, the thus-produced thin film is advantageous because it has excellent properties and the manufacturing process is simplified by ...

Embodiment 2

[0098] A UV curable antistatic solution with waterproof and antifouling effects was prepared, coated on one surface of a 36 μm thick PET film to a thickness of 0.1 μm, dried at 60° C. for 2 minutes, and then cured with 800 mJ of light. Also, on the other surface of the film, an acrylic adhesive was coated to a thickness of 15 μm.

[0099] The surface resistance of the film was determined to be 10 7 Ω / μm. The film was cut into a size of 25 mm×100 mm, attached to the polarizing film, and then peeled off at a rate of 300 mm / minute. As a result, the electrostatic voltage generated was 100V, and the decay time after application of 1000V was 1.8 seconds, so fast decay was not achieved.

[0100] The contact angle was measured to be about 93 using a surface tensiometer. When the film was pressed with a finger, no fingerprints were observed on the surface.

[0101] The hardness of the surface treated with antistatic treatment and waterproof and antifouling treatment was observed to...

Abstract

Disclosed is an antistatic pressure-sensitive or adhesive tape for protection. More particularly, this invention relates to an antistatic protective tape, in which, upon antistatic treatment using a conductive polymer on the exposed surface of the tape opposite the surface having an adhesive, water repellency able to increase the contact angle with respect to water so as to easily remove water drops in a water-using process and antismudge performance able to prevent the generation of smudges due to oil or to easily remove generated smudges may be imparted together, unlike conventional protective films. Further, the invention provides an antistatic composition, in which antistatic treatment using the conductive polymer and water repellent and antismudge treatment are not separately performed but are performed at the same time, so that these properties may be simultaneously exhibited in a single layer, thus decreasing the complexity of the process by one or more steps, and also providesa protective tape using the same.

Description

technical field [0001] The present invention generally relates to antistatic pressure sensitive or adhesive films, cloths or tapes (hereinafter "tapes") for use in protecting liquid crystal displays (LCDs) and electronic components. More specifically, the present invention relates to an antistatic composition for protective films and a protective tape using said composition, said composition being suitable for imparting all of the following properties: antistatic treatment to prevent the adhesion of impurities and minimize the generation of static voltage when removing the protective film; water repellency to minimize the contact of the surface with water to facilitate removal of water; Generation of stains and easy removal of generated stains, wherein antistatic treatment and water and stain repellent treatment are not performed separately as in conventional techniques, but are performed simultaneously, thereby simplifying the manufacturing process by eliminating one or more ...
