好ましい。[0010] The plasticizer is a component for controlling the drying speed and for imparting flexibility to the coating layer after drying. When performing the batch coating, since the thickness of the formed coating layer is large, it is important to prevent cracks and wrinkles from occurring during drying. For this reason, 6 to 50 parts by weight with respect to 100 parts by weight of the glass powder. Parts, preferably 10 to 35 parts by weight of plasticizer. When the amount of the plasticizer is less than 6 parts by weight, the drying speed becomes too fast, and the flexibility is insufficient, so that cracks and wrinkles are generated, so that a coating layer having a smooth and uniform film thickness cannot be formed by batch coating. Conversely, if the amount exceeds 50 parts by weight, a large amount of bubbles will be included after firing, and the withstand voltage of the dielectric layer will decrease. As plasticizers, dimethyl phthalate, diethyl phthalate, butyl benzyl phthalate, dioctyl phthalate, diisooctyl phthalate, dicapryl phthalate, dibutyl phthalate, diisobutyl adipate, dioctyl adipate, dibenzyl sebacate, dioctyl sebacate, triphenyl phosphate, phosphorus Tricresyl acid, trioctyl phosphate, octyl diphenyl phosphate, triacetin, chlorinated paraffin, camphor, castor oil and the like can be used, and these can be used alone or in combination. Among the above plasticizers, it is particularly preferable to use butylbenzyl phthalate, dioctyl phthalate, diisooctyl phthalate, dicapryl phthalate, and dibutyl phthalate alone or as a mixture.

る。The solvent is a component for adjusting the viscosity of the paste, and its content is preferably in the range of 30 to 60 parts by weight, particularly 35 to 55 parts by weight, per 100 parts by weight of the glass powder. If the solvent is less than 30 parts by weight, the viscosity of the paste becomes too high to obtain a coating layer having a smooth and uniform film thickness, and if it is more than 60 parts by weight, the viscosity of the paste becomes too low to obtain a desired film thickness. You can't get it. It is preferable to use a solvent having a boiling point of 150 ° C. or higher. This is because the drying of the coating layer formed by the batch coating is performed at about 80 to 120 ° C., so that the solvent having a boiling point of 150 ° C. or less is too fast dried, and the coating layer is easily cracked and wrinkled. It is because it becomes. As such a solvent, for example, terpineol,
Terpinyl acetate, dihydroterpineol, diethylene glycol monobutyl ether acetate, 2,
2,4-trimethyl-1,3-pentadiol monoisobutyrate or the like can be used alone or in combination.

The amount is preferably 0 to 30 parts by weight, particularly preferably 5 to 25 parts by weight with respect to 00 parts by weight. If the thermoplastic resin is more than 30 parts by weight, a large amount of bubbles will be included after firing. As the thermoplastic resin, polybutyl methacrylate, polyvinyl butyral, polymethyl methacrylate, polyethyl methacrylate, ethyl cellulose and the like can be used, and these can be used alone or in combination.

秒の条件で測定したときの値である。Further, the dielectric paste for a plasma display panel of the present invention has a viscosity of 150 to 700 poise, preferably 200 to 500 poise. By adjusting the viscosity of the paste to this range,
A coating layer having a thickness of 30 to 500 μm can be uniformly formed by the batch coating method. When the viscosity is less than 150 poise, it is difficult to form a coating layer having a desired film thickness in one application, so that the batch coating method cannot be adopted. Therefore, it becomes difficult to form a coating layer having a uniform thickness.
The viscosity referred to in the present invention is 23 ° C. and a shear rate of 5.7 /
This is a value measured under the condition of seconds.
