[0112]

[0113] The composition of the present invention can be prepared by kneading the above-mentioned components with a kneader such as a roll kneader, a stirrer, or a homomixer.

[0114] In addition, the composition of the present invention is a paste-like composition having fluidity suitable for coating and printing, and its viscosity is usually 1,000 to 30,000 cp, preferably 3,000 to 10,000 cp.

[0115] The composition of the present invention can be used particularly suitably for producing a transfer film (the transfer film of the present invention) described later, and is suitable for forming a dielectric layer of a PDP. In addition, the composition of the present invention can also be used in a conventionally known method for forming a layer of a film-forming material, that is, for directly coating or printing the composition on the surface of a substrate by screen printing or the like, and drying the coating film. In a method of thereby forming a film-forming mater...

Embodiment

[0144] The following are examples of the present invention, but the present invention is not limited to these examples. Materials used in Examples and Comparative Examples are as follows.

[0145] [glass powder]

[0146] Zinc oxide, boron oxide, silicon oxide, potassium oxide, calcium oxide, aluminum oxide (ZnO-B 2 o 3 -SiO 2 -K2 O-CaO-Al 2 o 3 class) mixture (softening point 565°C, specific gravity 2.79)

[0147] [adhesive resin]

[0148] Resins obtained in the following synthesis examples were used.

Synthetic example

[0150] Mix 150 parts of propylene glycol monomethyl ether acetate, 30 parts of n-butyl methacrylate, 70 parts of 2-ethylhexyl methacrylate and 1 part of azobisisobutyronitrile in an autoclave with a stirrer under nitrogen In the atmosphere, stir well at room temperature. After stirring, polymerize at 80°C for 4 hours, continue to polymerize at 100°C for 1 hour, and cool to room temperature to obtain a polymer solution. The polymerization rate of the obtained polymer solution was 98%, and the Mw of the copolymer (resin a) precipitated from the polymer solution was 90,000.

Abstract

The invention discloses to a resin compound with glass powder while it has better surface smoothness, when coating the film. The difference of surface smoothness of material layer will not generate the transfer film with worse shape to attain the PDP with better surface smoothness and film uniformity. It is characterized in that: it comprises: (A) glass powder, (B) adhesive resin, (C) silicyl and(D) metallic alcoholate.

Description

technical field [0001] The present invention relates to a resin composition containing glass powder, a transfer film and a method for producing a plasma display panel using the film. Background technique [0002] In recent years, plasma displays, which are flat fluorescent displays, have attracted attention. figure 1 It is a schematic diagram showing the cross-sectional shape of an AC type plasma display panel (hereinafter also referred to as "PDP"). exist figure 1 Among them, 1 and 2 are opposite glass substrates, 3 is a spacer, and the glass substrate 1, glass substrate 2 and spacer 3 are used to separate and form a unit. 4 is a transparent electrode fixed on the glass substrate 1, 5 is a bus electrode formed on the transparent electrode 4 in order to reduce the resistance of the transparent electrode 4, 6 is an address electrode fixed on the glass substrate 2, 7 is sealed in The fluorescent substance in the unit, 8 is a dielectric layer formed on the surface of the gla...
