Description
Technical field
The present invention relates to antistatic coating composition, particularly relate to following antistatic coating composition and the manufacture method of utilizing the antistatic films of said composition, described composition has excellent scuff resistance and solvent resistance, can fully suppress simultaneously electrostatic and produce, and have excellent antistatic property and durable reliability is changed.
Background technology
Among information-based industry, for most electronic units, static causes variety of issue.Static adsorbs the pollution substances such as dust of damage product properties when the manufacturing of electronic products.And modern electronics is also very high because of the tendency that static discharge is subjected to temporary transient or permanent damage.Particularly when making liquid crystal indicator, for polaroid attached to after peeling off special-shaped film with binder layer on the liquid crystal cell, produce static, the static of Chan Shenging exerts an influence to the liquid crystal aligning of liquid crystal indicator inside like this, thereby induced defect.
Surface protection film is attached on the surface of base material, protects the surface of base material thus.Representative example as the purposes of such film, dispatch from the factory at polaroid, preserve, when reprocessing, it on purpose is used for the quality inspection of polaroid, at this moment, static resistance when peeling off with light characteristic and film is a fundamental characteristics, requires it that external impact is had scuff resistance (scratch-resistant) and chemical resistant properties (solvent resistance) for the damage that prevents TAC (cellulosetri-acetate) film when the quality of polaroid is checked.
An example as the known technology that obtains antistatic effect, Mitsubishi chemistry polyester film (Polyester Film) society discloses a kind of antistatic polyester film in following patent documentation 1, this film uses diallyl dimethyl ammoniumchloride as static inhibitor, and in this film, use acrylic resin and polyvinyl alcohol as binding agent to improve the cohesive force of itself and base material, use melamine resin as solidifying agent in order to produce solvent resistance.But as the static inhibitor that uses in the above-mentioned patent, the polymer static inhibitor of cationic or anionic property demonstrates enough low resistance characteristic as protective membrane with static inhibitor, but still has problems.
On the other hand, as the static inhibitor that is used for antistatic layer, known have a multiple compound, wherein, discloses the electroconductive polymer body that makes thiophene (thiophene) derivative polymerization reaction take place and obtain in the following patent documentation 2 as static inhibitor.Disclosed electroconductive polymer has following feature: have high conductivity, have the transparency simultaneously, the adjusting of specific conductivity is easy, does not make the change in physical of base material, particularly it has following significant advantage: do not produce impurity, even also never kept through the several years specific conductivity with changing.But such electroconductive polymer has following shortcoming: compare with the low molecule-type or the polymer static inhibitor of general use, its price is higher, and it has the character of the light that absorbs the visible region and transmittance is reduced, and is disadvantageous to being used for blooming therefore.
And, a kind of protective membrane is disclosed in the following patent documentation 3, it is to use quaternary ammonium is that the polymer static inhibitor produces as the static inhibitor that constitutes antistatic layer.The polymer static inhibitor has following advantage: it uprises the weather resistance of antistatic layer, increase less because of static inhibitor moves the mist degree that causes to the top layer, and the less generation of adhesion (blocking), but general polymer static inhibitor has following shortcoming: the stretchiness deficiency, the coating coated film has fine cracking and does not have static resistance when using online coating (inline coating) manufacturing antistatic film.
