Description
Technical field
The present invention relates to be suitable as the scratch resistant resin board of display window protective panel of carrying type information terminal and the display window protective panel that has used the carrying type information terminal of this scratch resistant resin board.
Background technology
In recent years, along with popularizing of internet, portable phone and PHS (personal handyphone system, Personal handy-phone System) etc. the portable telephone type is popularized on a large scale as carrying type information terminal, and this carrying type information terminal not only has the function that the voice delivery function also has display text information and/or graphic information merely.In addition, except this portable telephone type, PDA (personal digital assistant, Persona Digital Assistant) also is widely used, and it also has internet function or e-mail function simultaneously except having functions such as address book.In this specification sheets, this portable phone, PHS, PDA etc. are referred to as " carrying type information terminal ".That is to say that alleged " carrying type information terminal " is to have the size of people's portability degree and have the general name of the product of the window (indicating meter) that is used for display text information, graphic information etc. in this specification sheets.
In these carrying type information terminals; come display text information, graphic information by liquid crystal, EL modes such as (electroluminescent), and usually use transparent resin system protecting sheet in its display window (open 2002-6764 communique, spy are opened the 2004-143365 communique, the spy opens the 2004-299199 communique) referring to for example spy.In order to prevent galled spots, proposed on this protecting sheet, to be provided with the scheme of the curing overlay film of scuff resistance by curable coating, also proposed by making curable coating contain the scheme that electrically conductive microparticle is given the curing overlay film static electricity resistance.
Summary of the invention
Above-mentioned curing overlay film is set on the one side at least of protecting sheet; when only being arranged on single face; only need this face get final product towards face side (side of the direct finding of user, contact), but the protecting sheet that only at single face curing overlay film is set exists and exposes to the open air for a long time in the hot and humid problem of generation warpage easily down.Therefore; it is better that curing overlay film is arranged on the protecting sheet two sides; but; in this case if when carrying out forming of two curing overlay films by the curable coating that does not contain electrically conductive microparticle; there is the crackly problem of protecting sheet when pushing; on the other hand, when carrying out the formation of two curing overlay films, there is the problem that is difficult to obtain sufficient scuff resistance by the curable coating that contains electrically conductive microparticle.
So; the artificial exploitation setting of invention is pushed and also is difficult for breaking and the display window protective panel of the carrying type information terminal of the curing overlay film that scuff resistance is high and specializing in; found that; by using the curable coating that does not contain electrically conductive microparticle to form the curing overlay film of a side; form the opposite side curing overlay film with the curable coating that contains electrically conductive microparticle; can obtain a kind of scratch resistant resin board; it is suitable as the display window protective panel of the carrying type information terminal with above-mentioned desired properties, thereby has finished the present invention.
Specifically, the invention provides a kind of scratch resistant resin board, it is characterized in that, form curing overlay film by the curable coating that does not contain electrically conductive microparticle on the one side of resin substrate, on its another side, form curing overlay film by the curable coating that contains electrically conductive microparticle.In addition, also provide a kind of display window protective panel that comprises the carrying type information terminal of this scratch resistant resin board by the present invention.
Scratch resistant resin board of the present invention has to push and is difficult for breaking and curing overlay film that scuff resistance is high, by with the display window protective panel of this scratch resistant resin board as carrying type information terminal, can effectively protect this display window.
Embodiment
As the resin of the substrate that constitutes scratch resistant resin board of the present invention, can enumerate for example methacrylic class acid resin, polycarbonate resin, polystyrene resin, styrene-acrylonitrile copolymer, tri acetyl cellulose resin etc.Wherein, the methacrylic resin transparency is high, rigidity is also high, so be suitable as the resin that constitutes substrate.
Methacrylic resin is the polymkeric substance based on methacrylic ester, can be the homopolymer of methacrylic ester for example, also can be other following monomeric multipolymers of above methacrylic ester of 50 weight % and 50 weight %.Under the situation for multipolymer, methacrylic ester shared ratio in whole monomers is preferably more than the 70 weight %, more preferably more than the 90 weight %.As methacrylic ester, preferably use alkyl methacrylate, especially preferably use methyl methacrylate.In addition, as the monomer beyond the methacrylic ester, can enumerate for example acrylate such as methyl acrylate, ethyl propenoate; Aromatic series such as vinylbenzene, vinyl toluene alkenyl compound; Unsaturated carboxylic acid such as vinylformic acid, methacrylic acid; Thiazolinyl such as vinyl cyanide, methacrylonitrile nitrile compound etc.
