Description
Technical field
The invention provides a kind of binder composition with antistatic property, and use this binder composition, form the bonding film of the binder layer with antistatic property and surface protection film at least one face of resin molding.Has excellent especially antistatic property according to bonding film of the present invention and surface protection film.Therefore, surface protection film of the present invention can be used in the purpose on the blooming surface of Polarizer that protection uses as building block with the plastic film that is easy to generate static, polarizer, antireflection film etc.
Background technology
All the time, in the manufacturing process of the blooming that constitutes the Polarizer of liquid-crystal display, polarizer, antireflection film etc., at the temporary transient coating surface protective membrane in the surface of blooming.When blooming is assembled into liquid-crystal display, surface protection film is peeled off and removed from blooming.For the surface protection film of protecting the blooming surface only uses, therefore, be also referred to as the operation film in manufacturing process.
The surface protection film that uses in the operation of making blooming forms binder layer in the one side with the polyethylene terephthalate of optical transparence (PET) resin molding.In addition, before fitting in blooming, will fit in for the stripping film of being stripped from processing of protecting this binder layer binder layer above.
And; because the blooming of Polarizer, polarizer, antireflection film etc.; be fitted with under the state of surface protection film; carry out the examination and test of products of the optical assessment that display capabilities, colourity, contrast gradient, impurity with LCD panel sneaks into etc.; therefore; for the surface protection film necessary performance be non-cohesive bubble or impurity in binder layer.
And, in recent years, need be at the antistatic property that surface protection film is prevented the excellence of static when the blooming of Polarizer, polarizer, antireflection film etc. is peeled off.This is because during from adherend release adhesive layer, and the charged electric control circuit of liquid-crystal display that might make when being accompanied by the peeling off of the generation of static electricity that produces breaks down.
And, even require blooming with Polarizer, polarizer, antireflection film etc. to fit in for example binder composition that also do not corrode, that have erosion resistance on the bezel (ベ ゼ Le) of metallic adherend.
And, require not pollute adherend from as the blooming stripper surface protective membrane of the Polarizer of adherend, polarizer, antireflection film etc. the time, namely do not produce adhesive residue.
Like this, in recent years, from being suitable for using the easy-to-use viewpoint of surface protection film, the performance that requires as for the binder layer that constitutes surface protection film requires: (1) has excellent antistatic property; (2) has erosion resistance; (3) prevent the generation etc. of adhesive residue.
Yet; though can satisfy as the independent performance that requires respectively for these (1)～(3) that require performance of the binder layer that constitutes surface protection film, all that are very difficult to satisfy simultaneously desired in the binder layer of surface protection film (1)～(3) require performance.
For example, about having excellent antistatic property, as the method for giving the surface protection film antistatic property, show and mediate into the method for static inhibitor to base material film etc.As static inhibitor, for example disclose (a) and had quaternary ammonium salt, pyridinium salt, uncle to the various cationic antistatic agents of the cation radical of uncle amino etc.; (b) has the anionic antistatic agents of the anion-radicals of sulphonate-base, sulfuric ester alkali, phosphoric acid ester alkali, phosphonic acids alkali etc.; (c) non-ionic antistatic agent of the both sexes static inhibitor of amino acids, amidosulphuric acid ester class etc., (d) alkamine, glycerols, polyethylene glycols etc.; (e) (patent documentations 1) such as polymer static inhibitor that aforesaid static inhibitor polymer quantification is obtained.
And, in recent years, not only propose to be included in such static inhibitor in the base material film or to coat the base material film surface, also propose directly to make binder layer contain such static inhibitor.
And, as static inhibitor use an alkali metal salt in the past, for example, disclose in the patent documentation 2 as the ionic species in (methyl) acrylic polymers, use a kind in the alkaline earth salt of an alkali metal salt that is selected from an alkali metal salt of perchloric acid, the alkaline earth salt of perchloric acid, organic boron complex and organic boron complex.But, contain the binder composition of the static inhibitor that is formed by an alkali metal salt, owing to have metal protection, therefore, be under the situation of metal at adherend, corrode.Therefore, the binder composition that need when having excellent antistatic property, have erosion resistance.
And, about preventing the generation of adhesive residue, for example proposed to mix the stiffening agent of isocyanate ester compound and specific silicate oligopolymer in the acrylic resin with 0.0001 ~ 10 weight part and the binder composition (patent documentation 3) that obtains for acrylic resin 100 weight parts.
In the patent documentation 3, be that the carbonatoms of about 2 ~ 12 alkyl acrylate, alkyl is that alkyl methacrylate of about 4 ~ 12 etc. is the principal monomer composition with the carbonatoms of alkyl, for example, can comprise monomer component monomer of containing carboxyl etc., that contain other functional group.Usually, preferably contain the above above-mentioned principal monomer of 50 weight %, and the content that hope contains the monomer component of functional group is 0.001 ~ 50 weight %, preferred 0.001 ~ 25 weight %, more preferably 0.01 ~ 25 weight %.Even since in the patent documentation 3 binder composition of record at high temperature or hot and humid down, cohesive force and bounding force through the time to change also be little, and, to also showing outstanding effect in the bounding force of curved surface, in addition, the foaming of tackiness agent or peel off does not take place.
Usually, if binder layer is made flexible proterties, then adhesive residue becomes and takes place easily.That is, become easily and peel off difficulty, the difficulty of fitting again when fitting mistakenly.Therefore, need to have functional group monomer crosslinked on host of carboxyl etc., binder layer is made certain rigidity, prevent the generation of adhesive residue.
In addition, about preventing the generation of adhesive residue, known have a following motion.Be that (methyl) alkyl acrylate and the multipolymer of copolymerization that contains carboxyl of the alkyl below 7 is as main component to have carbonatoms, with linking agent it is carried out crosslinking Treatment and obtain the acrylic adhesives layer, after fitting with this binder layer through for a long time, then tackiness agent to the transfer of adherend one side and for the bounding force of adherend through the time rise.In order to address this problem known following tackiness agent (pressure sensitive adhesive): it is that (methyl) alkyl acrylate of 8 ~ 10 alkyl is with the multipolymer with copolymerization compound of alcohol hydroxyl group, obtain (patent documentation 4) with linking agent to its crosslinking Treatment that described tackiness agent has carbonatoms by use.
Following tackiness agent etc. is also proposed: described tackiness agent by mixed with little amount (methyl) alkyl acrylate in above-mentioned same multipolymer with the multipolymer that contains the copolymerization compound of carboxyl, with linking agent its crosslinking Treatment is obtained.But surface tension is low when these tackiness agents are used for, during the surface protection of ganoid plastic plate etc., has owing to add man-hour or add the phenomenon of peeling off that thermogenesis floats etc. when preserving.
