Embodiment 1 to 7 and comparative example 1

[0098] (1) Preparation of glass paste composition

[0099] According to the composition ratio (unit: parts by weight) shown in Table 1 below, the binder resin, solvent, and other components were stirred and mixed for 3 hours to prepare an organic component, and then 40 parts by weight of this organic component (solid Content: 50%) and 80 parts by weight of (PbO-SiO 2 ) glass powder mixed and kneaded into a glass paste composition.

[0100] (2) Production of flake unbaked body

[0101]The resulting glass paste composition was coated on a support film made of polyethylene terephthalate with a lip coater, and the resulting film was dried at 100° C. for 6 minutes to completely remove the solvent. A glass paste film with a thickness of 60 μm was formed on the support film. Then, a polyethylene film having a thickness of 25 μm was laminated on the glass paste film to obtain a sheet-shaped unbaked body.

[0102] (3) Formation of dielectric layer

[0103] While peeling off the po...

Embodiment 8

[0141] (1) Production of flake unbaked body

[0142] Sheet-shaped unbaked body 1 was produced in the same manner as in Example 1, except that 0.5 parts by weight of an azo dye (trade name: Dye SS; manufactured by Daito Chemix Co., Ltd.) was added as a light absorber.

[0143] Then, a sheet-shaped unbaked body 2 was produced in the same manner as in Example 7 except that the thickness of the glass paste film was 40 μm.

[0144] (2) Formation of sheet-like unbaked laminate

[0145] While peeling off the polyethylene film in the sheet-like unbaked body 1, the green body 1 was laminated at 105°C on a glass substrate having bus electrodes thereon and preheated to 80°C with a hot roll laminator. Air pressure is 3kg / cm 3 , lamination speed is 1.0 m / min. Then the polyethylene terephthalate as a supporting film was peeled off.

[0146] Then, while peeling off the polyethylene film in the sheet-shaped unbaked body 2, the unbaked body 2 was laminated on the surface of the unbaked bod...

Abstract

An inorganic paste composition containing inorganic powders, a binder resin having a hydroxyl group in a side chain thereof, and an organic solvent having no hydroxyl group, and contains an organic solvent having a hydroxyl group in an amount equal to or less than 5% by weight. The composition gives a film having a uniform dispersion of the inorganic powders therein and uniform thickness. The resulting film does not cause much shrinkage.

Description

technical field [0001] The invention relates to an inorganic paste composition and a preparation method thereof, and a sheet-shaped unbaked body for producing a display panel by using the inorganic paste composition. Background technique [0002] Plasma displays form images by utilizing the discharge phenomenon to make a large number of micro-units (finecells) emit light by themselves. It has excellent characteristics, can form wide images, is thin, light and flat, and traditional displays cannot achieve these characteristics. The popularity of plasma displays was predicted. [0003] Conventional plasma displays mainly employ in-line structural cells in which ribs are formed only in the longitudinal direction, however recently, cells with a waffle structure have been developed in order to efficiently introduce light to the front of the plasma display. , wherein ribs are formed not only in the vertical direction but also in the horizontal direction. Having a grid structure ...
