Embodiment
Transparent hardened film of the present invention can solidify the hardened layer of realizing by coating one UV-light (UV) on one or two face of PET or TAC film, and said hard coat comprises (A) UV vinyl resin oligopolymer; (B) polyfunctionality UV Acrylic Acid Monomer; (C) PFPE of modification.
Being used to form the UV vinyl resin oligopolymer of the hard coat of transparent hardened film of the present invention, can be that functionality is 2～6 polyester acrylate, urethane acrylate or their mixture.Specifically comprise radical-initiated polymerisation type prepolymer and cationic polymerization type prepolymer.The example of radical-initiated polymerisation type prepolymer comprises the polyester acrylate prepolymer, epoxy acrylate prepolymer, vinylformic acid aminomethyl acid fat prepolymer and acrylic acid multielement alcohol ester prepolymer.Preferred 10～55 weight parts of the content of oligopolymer when being lower than 10 weight parts, can not guarantee the toughness of hard coat; And when being higher than 55 weight parts, because the relative minimizing of Acrylic Acid Monomer, the hard coat cross-linking set tails off; Make hardness to reduce, more preferably 15～50 weight parts.
The polyfunctionality UV Acrylic Acid Monomer that is used to form the hard coat in the transparent hardened film of the present invention can be that functionality is 3～6 low molecule UV monomers; Example comprises: three (methyl) vinylformic acid trihydroxymethylpropanyl ester; Three (methyl) vinylformic acid dipentaerythritol ester is with three (methyl) vinylformic acid dipentaerythritol ester of propionic acid modification, three (methyl) vinylformic acid pentaerythritol ester; Three (methyl) vinylformic acid trihydroxymethylpropanyl ester with the propionic acid oxide modifying; Isocyanuric acid three (acrylyl oxy-ethyl) ester is with five (methyl) vinylformic acid dipentaerythritol ester of propionic acid modification, six (methyl) vinylformic acid dipentaerythritol ester.Above-mentioned photopolymerizable monomer can use separately or use with two or more combinations.Preferred 5～45 weight parts of the add-on of Acrylic Acid Monomer, when being lower than 5 weight parts, the cross-linking set of hard coat tails off; Can not guarantee higher surface hardness; When surpassing 45 weight parts, cross-linking set is too much, causes effective molecule segment to shorten; Make hard coat crisp partially and toughness variation, more preferably 10～35 weight parts.
Hard coat of the present invention preferably contains the modification PFPE of unsaturated link(age) such as two keys as component (C) modification PFPE.This modification PFPE, the perfluor primary surface that can rely on it is active and move to the surface of filming, and reduces addition greatly.Simultaneously, this pair key modification PFPEs that contain can be through the crosslinking reaction of its two keys participation UV vinylformic acid film forming material, and like this, this stain control agent just is permanently secured to the surface of filming.Specific surface property by fluorine provides also can be kept for a long time, make film coated surface can be hydrophobic again can oleophobic, present low contamination property and easy cleaning performance.Its consumption is 0.2～2.0 part of modification PFPE.When the modification PFPE was lower than 0.2 weight part, the effect of adding the modification PFPE was with not obvious.When said consumption surpassed 2.0 weight parts, the performance of hard coat was with variation in the transparent hardened film of the present invention.Therefore, exceeding the consumption of above-mentioned scope, is inappropriate as being used for stain control agent consumption of the present invention.Preferably, the consumption of modification PFPE is in the scope of 0.5-1.0 weight part.
Flow agent according to the invention is not special to be limited, and is fit to flow agent of the present invention and can is: organo-siloxane or organic-silicon-modified vinylformic acid levelling agent are like BYK-307, BYK-377, BYK-354, BYK-306, BYK-333, Levaslip 407, Levaslip 410, Levaslip 411, Levaslip 432, Levaslip 466 etc.Consider the low haze requirement of transparent hardened film, the consumption of flow agent: calculate with 100 weight part applying materials, the flow agent consumption is 0.05～0.5 weight part, preferred 0.1～0.3 weight part.During less than 0.05 weight part; The levelling DeGrain; Consumption surpasses at 0.5 o'clock, can influence the levelling effect equally, and too much low molecule flow agent can influence the anti-fingerprint effect of PFPE aspect the cured film remained on surface; Can cause the mist degree of transparent hardened film to rise rapidly on the other hand, reduce the quality of transparent hardened film.
As long as do not have special demands can realize that various types of light triggers of coating curing all can as the light trigger that uses among the present invention.The light trigger of giving an example has: cracking type initiator: as: 2-hydroxyl-aminomethyl phenyl propane-1-ketone (1173), 1-hydroxy-cyclohexyl phenyl ketone (184), 2-methyl isophthalic acid-(4-methylthio group phenyl)-2-morpholinyl-1-acetone (907), benzoin dimethylether (651), 2; 4,6 (trimethylbenzoyl) diphenyl phosphine oxide (TPO) etc.; Photoinitiator (hydrogen-abstraction): like diformazan benzophenone (BP), 2-isopropyl thioxanthone (ITX) etc.Preferably: 2-hydroxyl-aminomethyl phenyl propane-1-ketone (1173) and 1-hydroxy-cyclohexyl phenyl ketone (184).Preferred 1～15 weight part of the consumption of initiator; During less than 1 weight part, influence the curing speed of applying material, be unfavorable for the raising of surface covered; When the consumption of initiator surpasses 15 weight parts; The top layer curing speed of applying material is too fast, is unfavorable for that the material below the top layer fully solidifies, and also can reduce the wear resisting property on surface.
If desired, after the component that forms hard coat is with organic solvent diluting and dissolving, can be coated with the coating fluid that comprises the component that is used to form hard coat of the present invention.As long as can on substrate film, form hard coat of the present invention, can use conventional organic solvent and have no restriction.Representative examples of organic comprises: aliphatic hydrocarbon such as hexane, heptane and hexanaphthene; Aromatic hydrocarbons such as toluene and YLENE; Halohydrocarbon such as methylene dichloride and ethylene dichloride; Alcohols such as methyl alcohol, ethanol, propyl alcohol and butanols; Ketone such as acetone, butanone, methyl ethyl ketone, 2 pentanone, and isophorone; Ester such as ETHYLE ACETATE and N-BUTYL ACETATE; And cellosolve based solvent such as ethyl cellosolve.Organic solvent can use separately or use with two or more combinations.Preferred 15～80 weight parts of the add-on of solvent, when solvent adding amount surpassed 80 weight parts, the consumption that too much solvent can be made the energy increased, and also is unfavorable for adjusting suitable thin hardened layer.When solvent was lower than 15 weight parts, the viscosity of system was too big, caused the leveling characteristics of hard coat not good enough; The thin layer coating is difficult to realize; In view of the optics requirement higher, be not suitable for again adding too many flow agent, so adopt the solvent of 15～80 weight parts that applying material is adjusted to cured film.More preferably add 20～50 weight parts.
As long as can form the hard coat among the present invention, the coating process that forms hard coat among the present invention is had no particular limits, and can use conventional method; Be coated with method like rod; The scraper coating method, the Mayer rod is coated with method, rolling method; The scraper plate coating method, mouthful mould coating method and intaglio plate coating method form coating.
Can merge H lamp or xenon lamp and obtain from high voltage mercury lamp as the ultraviolet ray that is used for hard coat medium ultraviolet light-cured type resin solidification of the present invention.Usually, the light quantity that is used to shine is in the scope of 100～500mj/cm2.
With regard to the hardness of hard coat in the transparent hardened film of the present invention,, can enough anti-scraping property be provided to transparent hardened film when pencil hardness is H or when higher.Preferably, the pencil hardness of hard coat is 2H or higher, so that demonstrate scrath resistance more fully.Within 2～20 micrometer ranges, select the thickness of hard coat.When thickness during less than 2 microns, the scrath resistance of transparent hardened film can not fully demonstrate.When thickness surpassed 20 microns, sometimes will form crackle and this thickness also was disadvantageous for producing.Preferably, hard coat thickness is in 2～15 microns scope.
The substrate film that is used for transparent hardened film can suitably be selected from the plastics film of routine.
The example of plastics film comprises: polyester film, and like polyethyleneterephthalate, polybutylene terephthalate and poly (ethylene naphthalate) film, polyvinylidene film, PP SHEET FOR OPP TAPE; Zellglas, diacetyl cellulose film, tri acetyl cellulose film, butyric acid ethanoyl cellulosefilm, polyvinyl chloride film; The polyvinylidene chloride film, PVA (PVOH) FILM, ethylene-vinyl acetate copolymer film, polystyrene film, polycarbonate film; Poly-methyl pentene film, polysulphone film, poly (ether ether ketone) film, polyethersulfone film; The polyetherimide film, fluorine resin film, polyamide layer, vinyl resin film; Urethane resin film, norbornylene-based polymer film, cycloolefin-based polymer film, cyclic conjugated diene-based polymer film and vinyl ester ring family hydrocarbon polymer film.
Polyethylene terephthalate thin film more preferably, tri acetyl cellulose film, polycarbonate film and norbornylene-based polymer film.
Thickness to substrate film has no particular limits.Usually, said thickness is at 20～300 microns, preferably in 50～250 microns scope.When this thickness during less than 20 microns, physical strength will be not enough, and such possibility will be arranged, and promptly when transparent hardened film is used for touch panel, the distortion through the pen input will be too greatly and durability not insufficient.When thickness surpasses 300 microns, when transparent hardened film is used for touch panel, the required pressure of deformation of thin membrane will be increased.Therefore, the thickness outside the appeal scope is worthless.
Like needs, one or two surface of substrate film can be handled or carries out surface treatment with undercoat, like oxidation or form uneven surface, so that the sticking power of each of arranging on the enhanced surface layer.Carrying out the surface-treated example through oxidation comprises: Corona discharge Treatment, utilize the processing (wet method) of chromic acid, and utilize the processing of flame, utilize to add the processing of warm air, or in the presence of ozone, utilize ultraviolet irradiation to handle.Forming the example that uneven surface handles comprises: sandblasting and utilize the processing of solvent.Surface treatment is suitably selected according to the kind of stromal surface.Usually, consider that from effect and operability Corona discharge Treatment makes preferably.
For characterizing anti-fingerprint pollutant performance, can characterize through surface energy usually, and fingerprint be human sweat's staple is water and various grease, characterizes surface energy with this according to the pure water of measuring the cured film surface and the contact angle of n-hexadecane.Preferably, the static contact angle of film top layer and water described herein is at least 90 °, and with at least 50 ° of the contact angles of n-hexadecane.More preferably, the static contact angle of itself and water is at least 100 °, and with at least 60 ° of the contact angles of n-hexadecane.
