Description
Technical field
The present invention relates to be used for to protect the adhesive film of the liquid crystal Polarizer that liquid crystal indicator uses, promptly directly be attached on the liquid crystal Polarizer, the transparent adhesive film of liquid crystal Polarizer protection that can fluoroscopic examination.
Background technology
For the liquid crystal Polarizer that uses in the liquid crystal indicator, damaging, pollute, adhere to foreign matter is fatal defective.Therefore, in manufacturing process, circulation operation and the assembling procedure of liquid crystal Polarizer, do not damage, do not pollute or non-cohesive foreign matter, take to attach the measure of protection adhesive film usually on the surface of liquid crystal Polarizer in order to make the liquid crystal Polarizer.The liquid crystal Polarizer that attaches the protection adhesive film will carry out defect inspection before being installed on the liquid crystal indicator.This inspection is carried out owing to attaching diaphragm, and therefore, claimed adhesive film has the high transparency.
And, in nearest checked operation and since on the protection adhesive film in spite of wound or the goods that pollute all handle as loss, therefore, also claimed adhesive film itself has anti-wound property and antistatic behaviour.For the wound of confirming the surface with pollute and whether to protect adhesive film itself, to wash with warm water or ethanol wiping sometimes, therefore, also must have water tolerance and resistance to chemical reagents.
When forming antistatic layer, for example, use and to contain anionic property antistatic agent or with the mix moisture prose style free from parallelism of the antistatic behaviour resin of its producing high-molecular, still with sulphonate-base etc., heatproof water-based and resistance to chemical reagents deficiency (for example, with reference to patent documentation 1 and patent documentation 2).The somebody has proposed for example adding non-response type silicone in the wearing layer, to improve the method for sliding etc. in order to improve the anti-wound property on stickability film surface, still, improves not enough.In patent documentation 1 and patent documentation 2, the method with ultraviolet isoreactivity energy line curing wearing layer is also disclosed.In the method, owing to when reaction, produce ozone gas etc., therefore, need exhaust equipment.
As the sticker that constitutes above-mentioned protection adhesive film, pay attention to the difficulty or ease of the transparency, clinging power control and non-polluting etc., therefore, using solvent-type acrylic usually is sticker (for example, referring to patent documentation 3).Because this protection adhesive film is peeled off in the way of LCD manufacturing process, therefore, the protection adhesive film must have the character of little stickability and releasable two aspects.But; under the situation of general little stickability sticker; exist in the circulation way of protection adhesive film under reeling condition and tunnel effect takes place (promptly; producing part between adhesion diaphragm and the stripping film peels off); perhaps on another face of the liquid crystal Polarizer that is pasted with this protection adhesive film, apply sticker again, the problem of tunnel effect or expansion takes place when drying easily.
Above-mentioned tunnel effect and expansion form the marking and manifest on adhering agent layer, have to cause to judge by accident in checking operation to be the problems such as reason of liquid crystal Polarizer defective.And, owing to have little stickability, therefore for example with the adherence deficiency of film base material such as Biaxially stretched clear polymer film and sticker, when peeling off, it is residual that pasty state takes place on liquid crystal Polarizer surface easily again.
As the stripping film used of protection adhesive film, use usually with face that sticker contacts on be coated with the film of remover.As this remover, use silicone-based remover and non-silicone-based remover.For example; for the silicone-based remover; though can design peeling force very light with the protection adhesive film; but exist owing to the mobile problem that causes that the liquid crystal Polarizer floats when pasting of silicone to the sticker aspect; and, also exist in order fully to carry out the high temperature that is solidified to form of silicone, film generation thermal shrinkage; cause the problem (for example, referring to patent documentation 4) of surface treatment obstacle by the pollution on liquid crystal Polarizer surface.
