Abstract
To provide a polyester film to be used as a base film of a brightness enhancement sheet (prism lens sheet) which has heat-resistant adhesiveness sufficient for enabling it to be preferably used for an in-car material or a high-luminance large screen display, and has a high transparency and shows a high adherence to a prism lens layer, a polyester film for a brightness enhancement sheet characterized by comprising a polyester film and a coating layer provided thereon, wherein the coating layer comprises an acrylic resin, a crosslinking agent and a polyoxyalkylenephenyl ether is used.
Description
Technical field
The present invention relates to be used for the polyester film of the blast sheet (being also referred to as " prismatic lens (prismlens sheet) " usually) of liquid-crystal display.
Background technology
The in recent years optical films that are used for of polyester film more, for example, be used for the blast sheet that liquid crystal indicator uses, touch panel, the basement membrane of backlight etc. or the antireflection basement membrane of film, the electromagnetic shielding film of plasma display, the basement membrane of OLED display, indicating meter explosion-proof with in the purposes such as basement membrane.
For the basement membrane that is used for this purposes, require the excellent transparency, and then require for the cementability and the adaptation that are arranged on layers of prisms on the basement membrane, hard coat, bonding coat, anti-reflection layer, sputtering layer etc.
But, polyester film, particularly biaxially oriented polyester film, cementability general and other material is poor, and is for example poor with the cementability that with the acrylic resin is the layers of prisms of main component or hard coat etc.
Wherein, as the method for the cementability that improves polyester film and layers of prisms, proposed much on the surface of polyester film, to be provided with the technical scheme (Japanese kokai publication hei 11-271503 communique, TOHKEMY 2000-141574 communique, TOHKEMY 2005-89622 communique, TOHKEMY 2006-137046 communique) that tackifier coating (ア Application カ one コ one ト Layer) improves cementability.
Summary of the invention
But in the existing technology, the thermotolerance of tackifier coating is not enough, if it is significantly impaired to be exposed to the next adaptation of hot environment, promptly heat-resistant fine adhesive function is not enough.Therefore, can not be as the equipment of vehicle mounteds such as auto-navigation system for example, or the parts of the big view display material of the high brightness that easily raises of temperature.
The objective of the invention is to, provide and have the enough heat-resistant fine adhesive functions that go for vehicle mounted equipment or the big view display of high brightness, and have the high transparency, show polyester film with the basement membrane that is used as blast sheet (prismatic lens) of the high adaptation of layers of prisms.
That is, polyester film for brightness enhancement sheet of the present invention is characterized in that, contains polyester film and the coating layer that is arranged on this polyester film, and coating layer contains acrylic resin, linking agent and polyoxy alkylidene phenyl ether.
Embodiment
Below the present invention will be described in detail.
Polyester film
The polyester that constitutes polyester film among the present invention is by aromatic diacid or its ester formation property derivative and glycol or its ester formation property derivative synthetic wire saturated polyester.As the concrete example of above-mentioned polyester, can enumerate polyethylene terephthalate, PEN, polybutylene terephthalate, poly-(terephthalic acid 1,4-hexamethylene two methylene esters).
The polyester that uses in the polyester film can be the multipolymer of these polyester, also can for the mixture of other resin.Under any one situation, all preferably based on the ratio little (for example 20 moles of compositions that % is following) of above-mentioned polyester (for example above compositions of 80 moles of %), multipolymer composition or mixing element.As polyester, polyethylene terephthalate is owing to the balance of mechanics rerum natura, optics rerum natura etc. is well and especially preferred.
Polyester film can contain tinting material, static inhibitor, antioxidant, lubricant, catalyzer, but adds particulate in the consideration of transparent aspect does not preferably contain.
The thickness of polyester film, necessary intensity in order to obtain using as the blast sheet is preferably 25～350 μ m, more preferably 50～250 μ m.
Coating layer
Polyester film for brightness enhancement sheet of the present invention also has coating layer except above-mentioned polyester film.Can preferably on the two sides, have coating layer having coating layer on the face or on two faces, having coating layer.
The thickness of the coating layer among the present invention is preferably 20～150nm, and more preferably 30～120nm is preferably 40～90nm especially.It is not preferred, on the other hand,, then not preferred if the thickness of coating layer above 150nm, then easily produces adhesion with the easy variation of adaptation of uv curing resin if less than 20nm.
Coating layer contains acrylic resin, linking agent and polyoxy alkylidene phenyl ether.Wherein, the effect of acrylic resin performance tackiness agent, the effect of heat-resisting adaptation is given in the linking agent performance.
When making the blast sheet,, so must have good cementability for acrylic resin because the layers of prisms that is arranged on the polyester film for brightness enhancement sheet is used the acrylic resin of energy-curable type, particularly ultraviolet hardening usually.Therefore, the binder constituents as coating layer uses acrylic resin.
Acrylic resin
The acrylic resin of the coating layer among the present invention is that the second-order transition temperature (following sometimes second-order transition temperature is called " Tg ") of polymkeric substance is preferably 30～80 ℃, 35～70 ℃ acrylic resin more preferably.The acrylic resin of Tg by using this scope can obtain having the film of the good adhesive and the excellent transparency.
