Description
Technical field
The present invention relates to the surface protection film that one fits in the surface of the opticses such as Polarizer, polarizer, indicating meter lens coating (, sometimes also claiming " optical film " below).More specifically, the invention provides a kind of surface protection film few to the pollution of adherend so have without through time deterioration excellent antistripping antistatic property surface protection film and be fitted with the optics of this surface protection film.
Background technology
At present; when manufacturing, the optical film of carrying Polarizer, polarizer, indicating meter lens coating, antireflection film, hard coat film, touch panel nesa coating etc. and when employing their optical articles such as indicating meter, prevented the surface contamination in subsequent handling, scratch by the surperficial coating surface protective membrane at this optical film.In order to save the labour and time that to carry out again after effects on surface protective membrane is peeled off fitting thus improve operating efficiency, for the visual inspection of the optical film as product, directly implement under the state of surface protection film of sometimes also fitting on optical film.
Since in the past, in the manufacturing process of optical articles, in order to prevent the attachment of scar, dirt, the one side being generally used in base material film is provided with the surface protection film of adhesive layer.Surface protection film is bonded on optical film by the adhesive layer of micro-cohesive force.Adhesive layer is set as the reason of micro-cohesive force is; in order to can easily peel off when the surface protection film of finishing using is removed from optical film sur-face peeling, and in order to prevent binding agent from adhering to and remain in as the phenomenon (the so-called generation preventing glue residue) on the optical film of the product of adherend.
In recent years; in the production process of display panels; the stripping static voltage produced when removing due to the surface protection film fitted on optical film is peeled off; the circuit blocks such as the drive IC of the display frame for controlling liquid-crystal display can be destroyed; the orientation of liquid crystal molecule is also had to damage, although the number of packages that these phenomenons occur is few also in generation.
In addition, in order to reduce the power consumption of display panels, the driving voltage of liquid crystal material is tending towards reducing, and the voltage breakdown of drive IC is also tending towards reducing thereupon.Recently, require stripping static voltage to control in the scope of+0.7kV ~-0.7kV.
In addition, in recent years, popularizing along with 3D indicating meter (autostereoscopic display), has the situation at the surface of the optical films such as Polarizer laminating FPR (patterned retarder, Film Patterned Retarder) film.After peeling off the surface protection film of fitting on the surface of the optical films such as Polarizer, then FPR film of fitting.But, when the binding agent used during the optical film surface of Polarizer etc. is by surface protection film, static inhibitor pollute time, there is the problem being difficult to paste FPR film.Therefore, for the surface protection film that this purposes uses, require that it is few to the pollution of adherend.
On the other hand; in some liquid crystal panel manufacturers; as the evaluation method of surface protection film to the contaminative of adherend; adopt with the following method: first the surface protection film that the optical film of Polarizer etc. is fitted is peeled off; fit again under the state being mixed into bubble; under prescribed conditions heat treated is carried out to the object after laminating again, then stripper surface protective membrane observe the surface of adherend.In this evaluation method; even if the surface contamination of adherend is micro-; if but between the part contacted at the binder phase of the part with surface protection film that are mixed into bubble, there is the difference of adherend surface contamination, then can remain as bubble impression (sometimes also referred to as " bubble stains ").Therefore, as the evaluation method of the contaminative to adherend surface, the evaluation method that can be strict.In recent years, according to the result of carrying out judging with this strict evaluation method, also need the no problem surface protection film in the surface contamination aspect of adherend.
In order to prevent from as the optical film of adherend during stripper surface protective membrane because peeling off the defect caused by static voltage height, someone proposes a kind of surface protection film, it uses containing for reducing the adhesive layer of static inhibitor peeling off static voltage.
Such as, in patent documentation 1, disclose the surface protection film of the binding agent that a kind of use is made up of the acrylic polymers of alkyl trimethyl ammonium salt, hydroxyl, polymeric polyisocyanate.
In addition, in patent documentation 2, disclose the adhesive composition that a kind of acrylate copolymer that is less than 1.0 by ionic liquid and acid number forms and the bonding sheet class employing said composition.
In addition, in patent documentation 3, disclose a kind of adhesive composition be made up of acrylate copolymer, polyether polyols, an alkali metal salt crossed by Anion-adsorption compound treatment and the surface protection film employing said composition.
In addition, in patent documentation 4, disclose the adhesive composition that a kind of polymkeric substance that is less than 0 DEG C by ionic liquid, an alkali metal salt, second-order transition temperature forms and the surface protection film employing said composition.
In above-mentioned patent documentation 1 ~ 4, be added with static inhibitor in adhesive layer inside.But the thickness of adhesive layer is thicker, and along with fitting in the time lapse after in adherend, the amount of the adherend movement that static inhibitor is fitted from adhesive layer to surface protection film can be more.When static inhibitor increases to the amount of adherend movement, the exterior quality as the optical film of adherend reduces; Or, when fitting FPR film, the possibility that the cementability that there is FPR film reduces.
In order to reduce the rheological parameters' change with time of the static inhibitor now shifting to adherend from adhesive layer, if reduce the thickness of adhesive layer, then other problem can be produced.Such as; when for applying the surperficial irregular optical films such as the Polarizer after anti-dazzle process to prevent from dazzling; adhesive layer cannot cater to the concavo-convex of optical film surface and be mixed into bubble; or; bond area due to optical film and binding agent reduces and reduces cohesive force, in use can there is the problem that protective membrane occurs to be separated or to peel off.
