Description

Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 406126: D / V. Description of the invention (彳) Scope of the invention The invention relates to a phosphorescent substance that can be applied to a display (such as a cathode ray tube). It can emit light efficiently after being excited by electron beam and ultraviolet rays. The phosphorescence properties of the present invention can improve the density of phosphorescence in a phosphorescence film coated by a method such as a slurry coating method and a paste coating method, improve the dispersibility of the phosphorescence, and form a dense body. The phosphorescent film can increase the luminous intensity of the phosphorescent film and cause an image with excellent color purity and contrast. Prior art phosphorescent display screens (eg, cathode ray tubes) have a black matrix (hereinafter referred to as "BM") containing a black non-luminescent substance on the inner surface of its panel (glass panel) to improve its contrast And, a coating containing polyvinyl alcohol (PVA) is formed on the black matrix (BM) to make the panel compatible with the phosphorescent slurry. Thereafter, three kinds of G (green) 'Β (blue) and R (red) phosphorescent slurries were sequentially applied thereon, and then the photoluminescent printing method (exposure and development) was used to form a phosphorescent thin film. The appearance of "fogging" during the formation of such a phosphorescent film will reduce the color purity and contrast quality of the phosphorescent screen. The above-mentioned atomization phenomenon can be summarized into the following points: (1) "Atomization on BM": This phenomenon is caused by the reduction of the contrast quality due to the phosphorescent residue and deposition on the black matrix (BM); Applicable to China National Standard (CNS) Α4 specification (210 × 297 mm) ~ -4- (Please read the notes on the back before filling this page) Printed by the Staff Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 406126 A7 B7 V. Description of the invention (2 ) (2) "Atomization on glass": This phenomenon is caused by the decrease in the color purity and quality of the phosphorescent film formed by the phosphorescent residue and deposition on the surface; and (3) "cross pollution": This phenomenon is due to the appearance of particles of the phosphorescent coating applied later, which reduces the color purity quality of the coated phosphorescent film. For example, "B / G" cross-contamination means that B contaminates the G phosphorescent film, and "R / G" cross-contamination means that R contaminates the G phosphorescent film. Therefore, it is necessary to improve the phosphorescent particles in order to reduce the "haze", to improve the color purity and contrast, and to improve the filling density of the phosphorescent to improve the luminous intensity of the phosphorescent film. In order to solve the above-mentioned problems caused by the fogging phenomenon and the phosphorescent filling density of the phosphorescent film, the present inventors have chemically treated the phosphorescent surface with various surface-treatment substances, and found that the phosphorescent filling density and atomization The phenomenon is related to the surface zeta potential isoelectric point of the surface treated phosphor and the blow-out charge generated when it contacts the red glass beads coated with PVA. The above problems can be treated with a special surface on the phosphor Solve by substance coating. Therefore, the present invention is to provide a phosphorescent material, which can improve the filling density of the phosphorescent film formed by the phosphorescent material, and the phosphorescent surface can be treated with a special substance to avoid fogging. In order to solve the above-mentioned problems, it has been suggested in the past that special organic compounds and / or inorganic compounds be added to change the phosphorescent surface (see P-B-63 — 66876, JP-A — 63 — This paper standard applies to Chinese national standards ( CNS) A4 size (210X297mm) (Please read the notes on the back before filling out this page) -Order-5- Printed by the Consumers' Cooperative of the Central Standards Bureau of the Ministry of Economy 406126 V.

For example, when the phosphorescent surface is uniformly treated with an anionic compound (that is, a negatively charged substance) (for example, silicon dioxide and acrylic resin in J PB — 6 3 -6 6 8 7 6) or a non-ionic When a compound (for example: polystyrene resin in JP — B — 64-5 737) is uniformly treated, the isoelectric point of the zeta potential of the phosphorescent substance is about 7 or less after this treatment, but its blown charge is still Low, so there is still fogging. In addition, according to JP — B — 63 — 66876 and JP — A 1 3 2 7 3 0 8 8, the phosphorescent surface is oxidized with a cationic substance (ie, a positively charged substance), such as an alkali metal or alkaline earth metal. Improved treatment of materials, bases or similar coupling agents. After this treatment, the blowing charge of the phosphorescent light can be about 5 # C / g or higher, thereby reducing the fogging phenomenon and improving the phosphorescent phosphor screen. Color purity and contrast, but its zeta potential isoelectric point has been raised to about 7 or more, thereby reducing the charge density of phosphorescent films when forming phosphorescent films, and reducing the luminous intensity. In the present invention, "blow-out charge" means a blow-out charge generated when contacted with a glass bead having a particle size between 200 and 800 em and having a PVA coating on its surface.

According to the detailed description of the present invention, the above problems can be solved with a surface Zeta potential isoelectric point up to 7 and a negative 5 μ C / g blow. The electrical charge (when it comes in contact with glass beads with a particle size of 2000 to 800 'on the surface coated with polyvinyl alcohol) is resolved by phosphorescence. Printed by the Consumer Cooperatives of the Central Government Bureau of the Ministry of Economic Affairs (please read the back first) Note: Please fill in this page again.) The first type of phosphorescence defined in the above (1) of the present invention, the basic phosphorescence used includes phosphorescence which can be used as a phosphorescent film for a display, for example: ZnS: Ag, A1 Blue-emitting phosphorescence; ZnS: Ag, C1 blue-emitting phosphorescence and ZnS: Zn blue-emitting phosphorescence; or Y203; Eu red-emitting phosphorescence; and Y2〇2S: Eu red-emitting phosphorescence; or ZnS: Cu, A1 emits green phosphorescence and Zn S: Cu, Au, A1 emits green phosphorescence, etc., for use as cathode ray tubes. In addition to the above examples, any phosphorescent material suitable for general display can be used as the basic phosphorescent material for the first phosphorescent material of the present invention.

Description of the invention (6) The particle size of the phosphor is usually between about 1 and 10 microns, and it can be selected depending on the situation of the phosphor film of the display. Silane compounds used in the treatment of phosphorescence may include: Hydrophobic compounds disclosed by Ip B-53-17555 and JP-B-62-4778, and one of the compounds disclosed in JP-B-6-3-6 6 8 7 6 The amine groups of silane compounds, however, the disadvantages of such compounds are that the blown charge of the coated surface layer on the phosphorescent surface is not easy to increase, and the amine group is easily hydrolyzed in the coating slurry, so that p Η in the slurry値 increases, which in turn reduces its exposure sensitivity. The quaternary ammonium salt alkoxy metal compound (hereinafter referred to as "alkoxy compound") contained in the phosphorescent substance of the present invention is preferably one having an alkyl group or an allyl group on the ammonium salt side chain of the alkoxy compound. Examples of the alkoxy compound include compounds having the above-mentioned general formula, and alkoxy compounds having _OCH3, -〇C2H5, _0 (: 3 ^ 18 or -0 (: 4119) are particularly suitable as the alkoxy group. When it is deposited on the phosphorescent surface, the hydrophilicity and hydrolyzability of the phosphorescent surface can be stabilized. In addition, the alkyl or allyl group bonded to the side chain of the ammonium salt has 1 to 2 4 carbon atoms, preferably 3 To 18, and if the carbon number is increased, it is difficult to disperse the ammonium salt in the preparation of the slurry, so it is appropriate to add non-ionic surfactants and the like to help its dispersibility. In addition, the η 値 should be from 1 to 8, preferably from 2 to 4. Examples of the metal element M include: Si, Ti, and Zr, and the silane compound in which M is Si is particularly suitable for the purpose of the present invention. For the first phosphorescent material, the surface of the phosphorescent material may be coated with a surface treatment agent, for example, special ^^-1.

Description of the Invention (7) Anionic organic compounds and / or inorganic compounds, as disclosed in [P-A-6 3 -284299]. Examples of such anionic organic compounds that can be pre-coated on the phosphorescent surface include: a binding agent to adhere the pigment to the phosphorescent agent; and a dispersant to improve the dispersibility of the phosphorescent agent in the phosphorescent slurry, such as polypropylene Sodium phthalate, sodium citrate, gum arabic, or cellulose formulated with carboxyl groups, etc. At the same time, examples of anionic inorganic compounds that can be pre-coated on the phosphorescent surface include S i, P containing a hydroxyl group in the molecule , Ge, T i or Z η hydroxides, and substances which can be coupled with "alkoxy compounds" and deposited are particularly suitable. In addition, such compounds are added to the phosphorescent slurry to adjust its P Η 値 to It is better to use a uniform and small amount of the surface. At the same time, the amount of the compound for surface treatment containing the above organic and / or inorganic compound can be applied in an amount depending on the type of compound used and the application.

When the phosphorescent film processed by this method is used to prepare a phosphorescent film, the phosphorescent charge density in the phosphorescent film is deteriorated, and the luminous intensity of the formed phosphorescent film is easily weakened. At the same time, when the coating amount is higher than 2 'OOOppm (such as silica sol), it will be difficult to adhere to the phosphorescent substance and easy to peel off from the phosphorescent substance.

However, since the "alkoxy compound" as the first phosphorescent treatment agent of the present invention is water-insoluble, once adsorbed on the phosphorescent surface, it can adhere to the phosphorescent surface fairly and can control the phosphorescence robustly. Surface charge without dissolving the phosphor-coated slurry. In addition to the coating method described above, the "alkoxy compound" can be coupled to the surface of the silica particles, and the product can be deposited on the phosphorescent surface in the gas phase, and the "alkoxy compound" can be coated on the phosphorescent surface. Hereinafter, the preparation method of the second phosphorescent substance defined in the foregoing (5) of the present invention will be described in detail. The type and particle size of the basic phosphor used in the second phosphor as defined in the foregoing (5) of the present invention may be the same as the first phosphor as defined in the (1) of the present invention. Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the notes on the back before filling this page) The non-anionic or anionic compound used to prepare the second phosphorescent substance of the present invention is an inorganic or organic substance, which The zeta potential isoelectric point 表面 of the particle surface is at most 7 ′, which can appropriately react with a compound containing a cationic quaternary ammonium salt to control the charge on the phosphorescent surface. Examples of this non-anionic or anionic compound include: organic silicon Compound particles, such as: sand sol, powdered sand or hydrolyzed sand, or organic anionic carboxyl modified propylene-based emulsion, SBR particles, latex emulsion-anionic polymerization surfactant, or Non-anionic polystyrene granules This paper is sized for the Chinese National Standard (CNS) A4 (210X297 mm). -12- Printed by the Bayer Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 406126 B7__V. Description of the invention (10) For organic particles, MF T (the minimum temperature necessary to form a continuous film) can be controlled to at least 10 ° C to prevent deformation Atomization caused by thermal softening during the drying process when forming a phosphorescent film. The particle size of non-anionic or anionic compound particles should preferably be between 80 and 300 nanometers (my). When the compound and particle size containing a quaternary ammonium salt When particles with a size of less than 8 Om / z are used, the phosphorescence is easy to aggregate, which deteriorates the phosphorescence of the phosphorescent film. On the other hand, when particles with a particle size greater than 30 Om / z are used, the particles are not easy to adhere. On the phosphorescent surface, after the compound containing a quaternary ammonium salt is deposited, its zeta potential isoelectric point is easily higher than 7, so that the charging of the phosphorescent film in the phosphorescent film becomes worse. A more suitable particle size range is between 100 and 100. ~ 200m / z. The particles in this size range can be properly adhered to the phosphorescent surface, and the surface charge is easily controlled in a system coexisting with a cation-containing quaternary ammonium salt compound. The second phosphorescent substance of the present invention The compound containing a quaternary ammonium salt may include, in addition to the "alkoxy compound", polyvinyl alcohol, polydiallyl-quaternary ammonium salt adduct, and interfacial activity with the addition of a quaternary ammonium salt Quaternary ammonium Silane coupling agents, etc. Since compounds containing quaternary ammonium salts are more cationic than other cation-containing compounds and can easily increase their blow-out charge, such compounds are more suitable. When the second phosphorescent substance is used When the cation containing a quaternary ammonium compound (other than an "alkoxy compound") is used alone, the objective effect of the present invention is not often achieved, but if it is used in combination with the above-mentioned non-anionic or anionic compound, The two compounds can react appropriately to each other, so it is easy to control their phosphorescent surface charges and achieve the purpose of the invention.

Meanwhile, as shown in Comparative Example 5, when the green and red phosphorescent films adjacent to the blue phosphorescent film have a low blow-out charge 値, their atomizing properties are not stable and can be easily changed. In addition, as shown in Comparative Example 6, when the deposit is a cationic aluminum sol, its zeta potential is relatively high, and the phosphorescent charge density in the phosphorescent film is poorer than those using a compound containing a quaternary ammonium salt. As stated in the text, the present invention can provide a phosphorescent material having a suitable surface potential (e.g., Zeta potential isoelectric point and blown charge).
