The present invention relates to a PDP filter, and more particularly, a film for a plasma display panel filter (hereinafter referred to as a PDP filter) having almost no change in transmittance due to excellent thermal stability, a PDP filter including the same, and the PDP filter. It relates to a manufactured plasma display panel.

Recently, in implementing a large screen among flat panel displays, plasma display panels have been in the spotlight. FIG. 1 is a diagram illustrating a structure of a plasma display panel, and a schematic view of the panel assembly 13 in the plasma display panel is shown in detail in FIG. 27. The plasma display panel assembly may form partition walls partitioned on the lower plate, and then form red, green, and blue phosphor layers in the grooves of the partition wall, and may be disposed in parallel with the electrodes of the lower plate and the electrodes of the upper plate facing each other. It is formed by overlapping the upper plate and encapsulating discharge gas such as Ne, Ar, and Xe, and is generated when the ultraviolet rays emitted from the plasma generated when the gas is discharged by applying voltage to the electrodes of the anode and the cathode strike the phosphor. It is a next-generation display that combines light to provide images.

As shown in FIG. 27, the plasma display panel has electrodes for supplying signals and power to the entire front surface of the plasma display panel, so that a large amount of electromagnetic waves are generated and near-infrared rays are generated in comparison with other displays, so that light of the near-infrared region is generated. A malfunction of the remote control or infrared communication port specified for the communication will occur. In addition, after filling the discharge gas of Ne, Ar, Xe, etc., three primary colors are emitted by emitting light of red, blue, and green phosphors by vacuum ultraviolet rays. When the neon atoms return to the ground state after excitation of the neon atoms, they are around 590 nm. There is a problem that the bright red of the neon orange light can not be obtained.

In order to solve such a problem of the plasma display panel, a plasma display panel filter (hereinafter referred to as a PDP filter) 14 is provided on the front surface of the panel assembly 13. 2 and 3 are views showing the ultimate purpose of installation of the PDP filter. 2 and 3, when the PDP filter is installed, visible light of R, G, and B passes through the filter as it is, and an orange wavelength of 590 nm wavelength and 800 to 1000 nm that decrease the resolution of the screen. Near-infrared rays of the wavelength band are blocked.

PDP filters generally have a structure in which several films (anti-reflective film (AR film), near-infrared shielding layer (NIR film), neon cut layer (neon cut film or color correction layer), electromagnetic shielding film (EMI film), etc. are laminated. The near-infrared absorbing film and the neon-cut film have a structure in which a near-infrared absorbing dye, a neon cut dye, and a color control dye are added to the polymer resin and coated on a transparent substrate, respectively.

The near-infrared shielding layer (near-infrared absorbing film, NIR film) should all have good durability even under high temperature or high temperature and high humidity conditions, and should have a high absorption rate of near infrared rays having a wavelength of 800 to 1200 nm, especially 850 to 1000 nm. The transmittance for visible light having a wavelength of 700 nm must be at least 60% to be preferably used in a PDP filter. In addition, the neon cut dye should have a maximum absorption wavelength in the vicinity of 570 ~ 600nm, the half width band (half width band) of these is better the narrower, preferably 40nm or less.

As a binder resin used in the manufacture of a near infrared absorbing film or a near infrared absorption / color correction composite film, a resin capable of forming a transparent film may be generally used. Specifically, polyester, acrylic, melamine, urethane, and polycarbonate may be used. Systems, polyolefins, polyvinyls, polyvinyl alcohols, polystyrenes, copolymers of these resins and the like are used.

Meanwhile, as dyes for producing near-infrared absorbing films, which are widely used, diimmonium salts, quinones, phthalocyanine, and naphthalocyanine metal complexes, which absorb near infrared rays and transmit visible light, are used. complex) dyes, or cyanine dyes (polymethine dyes). Meanwhile, as neon cut dyes, polymethine dyes or porphyrine dyes are widely used.

Such near-infrared absorbing dyes or neon cut dyes should have a high wavelength absorption in a predetermined range, have excellent transmittance of visible light, and are particularly important for heat generation from PDP. In this case, durability should be excellent. Among the near-infrared dyes listed above, phthalocyanine, naphthalocyanine, and dithiol-based metal complex dyes are known to be excellent in thermal stability. However, the dyes do not absorb light in a wide range of near infrared rays because the near infrared absorption peak is sharp, and the manufacturing cost of the near infrared absorbing film is high because the price is high. In addition, in the case of cyanine dyes, there is a problem that storage stability is not good, such as durability deteriorates when stored for a long time under high temperature and high humidity conditions.

In contrast, when the dimonium salt dye is used, the near-infrared absorption peak is broad, and the visible light transmittance is excellent, and in terms of price, it is cheaper than the phthalocyanine, naphthalocyanine, and dithiol-based metal complex dyes. It can be lowered. However, even in the case of dimonium salt dyes, there is a problem in that the physical properties of the dye are deteriorated due to a decrease in the ability to absorb near infrared rays and a change in transmittance in the visible region when stored for a long time under high temperature or high temperature and high humidity conditions. The durability of such a near-infrared absorbing film varies greatly depending on not only the dye itself but also the type of binder resin used to form the film. Various binder resins have been developed to improve the durability of the dimonium salt dye.

U.S. Patent Publication No. US6117370 discloses a near-infrared absorption filter prepared using polycarbonate resin as a binder resin and dimonium dye as a near-infrared absorbing dye. However, chloroform is used as a solvent during film formation. Since the recovery system of the entire amount of the remaining chloroform used as the solvent must be provided separately, and the thermal stability of the dimonium dye is not improved so much, there is a problem that the change in the transmittance after a long time at a high temperature and high humidity condition is still large. .

In addition, US Patent Publication No. US6522463 discloses a near infrared absorption filter prepared using a polyester copolymer resin as a binder resin and a dimonium dye as a near infrared absorbing dye. Due to thermal stability, there was a problem that the change in transmittance is still large.

Accordingly, the first technical problem to be achieved by the present invention is a PDP filter film which has excellent durability due to a small change in transmittance under high temperature or high temperature and high humidity conditions, and a general organic solvent can be used when manufacturing a film. To provide.

The second technical problem to be achieved by the present invention is to provide a PDP filter comprising the film.

The third technical problem to be achieved by the present invention is to provide a PDP manufactured using the PDP filter.

The present invention to achieve the first technical problem,

Binder resin consisting of a SAN copolymer; And

Provided are a film for a PDP filter comprising any one dye selected from the group consisting of near-infrared absorbing dyes, neon cut dyes, color correction dyes, and mixtures thereof.

In addition, the content of acrylonitrile units in the SAN copolymer may be 10 to 50 wt%.

In addition, the weight average molecular weight of the SAN binder resin may be 10,000 ~ 1,000,000 and the glass transition temperature may be 100 ~ 120 ℃.

According to another embodiment of the present invention, the near-infrared absorbing dye may be any one selected from the group consisting of dimonium salt, quinone, metal complex, phthalocyanine, naphthalocyanine, polymethine (cyanine), and mixtures thereof. .

According to another embodiment of the present invention, when the near infrared absorbing dye is a dimonium dye, it is preferable that the weight ratio of the binder resin and the near infrared absorbing dye is 5: 1 to 200: 1.

In addition, the neon cut dye has a maximum absorption wavelength of 570 ~ 600nm, it may be a polymethine dye or porphyrin dye.

The present invention provides a PDP filter comprising the film in order to achieve the second technical problem.

The present invention provides a PDP manufactured using the PDP filter in order to achieve the third technical problem.

Hereinafter, the present invention will be described in more detail.

The film for PDP filter according to the present invention is characterized in that the thermal stability of conventional near-infrared absorbing dyes, such as dimonium salt dyes, can be improved by using a SAN copolymer as the binder resin, so that there is almost no change in transmittance. In the case of the copolymer, since a general organic solvent can be used as a solvent, it is easy to manufacture a film and has an advantage of reducing environmental pollution problems.

SAN copolymer refers to a copolymer of styrene-acrylonitrile and has excellent optical transparency, heat resistance, chemical resistance, dimensional stability, etc., and particularly excellent durability and thermal stability due to small change in transmittance under high temperature and high temperature and high humidity conditions. It has the advantage of excellent stability.

The weight average molecular weight of the SAN copolymer used in the present invention is preferably 10,000 ~ 1,000,000, the glass transition temperature (Tg) is preferably 100 ~ 120 ℃, when the weight average molecular weight is less than 10,000, heat resistance, chemical resistance, etc. If the amount is not sufficient, and exceeds 1,000,000, there is a problem in that polymerization is difficult due to high viscosity, polymerization temperature, heat of reaction, and the like during polymerization production. Moreover, when Tg is less than 100 degreeC, since heat resistance is not enough, durability of a film will worsen after manufacture of a film, and when Tg exceeds 120 degreeC, it is not preferable because there exists a problem that solubility and handling become difficult. On the other hand, the content of the acrylonitrile unit of the SAN copolymer is preferably 10 to 50 wt%, when the content of the acrylonitrile unit is less than 10 wt%, the heat resistance and chemical resistance of the resin is poor, durability after film production This sharply worsens, when the content exceeds 50 wt% there is a problem in that black spots (black spot) occurs during the manufacturing of the resin can not be used as a transparent optical material.

The near-infrared absorbing dye that may be used in the present invention may be any one selected from the group consisting of dimonium salts, quinones, phthalocyanines, naphthalocyanines, metal complexes, cyanines and mixtures thereof.

When the near-infrared absorbing dye is a dimonium dye in the PDP filter film according to the present invention, the weight ratio of the binder resin and the near-infrared absorbing dye may be 5: 1 to 200: 1, but the binder resin may be included in less than 5 parts by weight. In this case, the durability improvement effect of the produced film cannot be expected, and when the binder resin is more than 200 parts by weight based on 1 part by weight of dye, the amount of the dye is relatively decreased compared to the content of the binder, which tends to reduce the near infrared absorption rate.
