The neon yellow light absorbing filter film consisting of the triphenyl methane dye has excellent high-temperature and humidity resistance and low cost, and can improve the image resolution and color purity when being used for the plasma display panel.
Description
Technical field:
The present invention relates to shielding electromagnetic wave, near infrared ray and improve the purity of color technical field, more particularly relate to a kind of neon yellow light absorbing dye that absorbs the neon gold-tinted that stops, also relate to the purposes of this neon yellow light absorbing dye.
Technical background:
In recent years, along with the growth of requirement to big and thin indicating meter, plasma display panel (PDP) becomes more and more universal.Yet the PDP assembly is launched a large amount of hertzian wave, near infrared ray in working order the time, also produces the orange-colored light of being sent by helium (He) and xenon (Xe).In order to overcome above-mentioned shortcoming, using plasma display panel spectral filter shielding electromagnetic wave, near infrared ray and improve purity of color etc. at present.Plasma display panel filter is made up of electromagnetic wave proof cover, near infrared ray barrier filter and neon gold-tinted absorption filter etc.
Neon yellow light absorbing dye absorbs the neon orange-colored light of the 590nm that sends when returning ground state that is stimulated, thereby improves the resolving power and the purity of color of PDP screen.Existing document has proposed with porphyrin class, polymethine class and anthraquinone dyes as neon yellow light absorbing dye.Spectral filter, color compensation film and PDP spectral filter with the cyanine class dyestuff preparation of different structure are disclosed respectively as Chinese invention patent CN 1969205A and CN 1860578A.U.S. Pat 7506977 discloses the spectral filter with the preparation of tetraazatetradecane porphyrin class dyestuff.

Described triphenylmethane dye is to have maximum absorption wavelength at visible region 570nm-610nm.
Two of purpose of the present invention can realize by following technical measures:
Described neon yellow light absorbing dye is used for the neon gold-tinted and absorbs filter coating, plasma display panel filter or plasma display panel.
The preparation process that the neon gold-tinted that the present invention relates to absorbs filter coating is that neon yellow light absorbing dye of the present invention is dissolved in the organic solvent, mixes with macromolecule resin or tackiness agent then, is coated on separability base material or the transparent carrier film, and drying forms.
Described organic solvent is a solvent commonly used in this area, can be fragrant families such as toluene, dimethylbenzene, chlorinated hydrocarbon such as chloroform, methylene dichloride, alcohols such as methyl alcohol, ethanol, acid amides such as dimethyl formamide, N,N-DIMETHYLACETAMIDE, methyl-2-pyrrolidone system, ketone such as acetone, butanone system, tetrahydrofuran (THF) etc.These organic solvents can use separately, also can mix use as required.
The kind of described macromolecule resin or tackiness agent is not particularly limited, and visible region is transparent, and has excellent thermostability and the polymer of ageing-resistant performance all can use.Macromolecule resin can be thermoset or thermoplastic resin, comprises silicone resin, urethane resin, acrylic based resin, fluorocarbon resin, Synolac, Resins, epoxy etc.; Tackiness agent can be pressure sensitive adhesive, heat sensitive adhesive or photosensitive adhesive, comprises acrylic adhesives, polyurethane binding etc.
Neon gold-tinted of the present invention absorbs filter coating can comprise the color correction dyestuff that can regulate neon gold-tinted absorption filter coating color.The color correction dyestuff generally is the organic dye that has maximum absorption wavelength at visible region 400nm to 700nm, as anthraquinone class, cyanine class, phthalocyanines, azo class etc.The color correction dyestuff can mix with neon yellow light absorbing dye and be dissolved in the organic solvent, mixes with macromolecule resin or tackiness agent again, applies into the thin film that existing neon gold-tinted absorbs color adjustment again; Also can be dissolved in solvent separately, mix with macromolecule resin or tackiness agent again, apply the thin film that color adjustment is only arranged.
Neon gold-tinted of the present invention absorbs filter coating and further is included in the hear-infrared absorption dye that near infrared region 800nm to 1200nm has maximum absorption wavelength.Hear-infrared absorption dye can be the conventional dyestuff that uses, as organic dye such as diimine class, thio diene nickel class, cyanine classes.As required, above-mentioned hear-infrared absorption dye can use individually or simultaneously.Hear-infrared absorption dye can mix with neon yellow light absorbing dye, color correction dyestuff and film or film separately.
The invention further relates to and comprise that above-mentioned neon gold-tinted absorbs the plasma display panel filter and the plasma display of filter coating.
As neon yellow light absorbing dye, this dyestuff has excellent thermotolerance, wet fastness and lower cost with triphenylmethane dye.The neon gold-tinted of being made up of above-mentioned triphenylmethane dye absorbs the high temperature resistant moisture resistance properties that filter coating has excellence, and cost is lower, is used for plasma display panel and can improves image resolution ratio and purity of color.
