Problems solved by technology

However, the existing screen printing method requires a very high technical level. During the screen printing process, the paste will leave the substrate due to its low viscosity, resulting in a decrease in the accuracy of the screen. Obtaining large-screen patterns with high precision required for PDPs in the screen printing method
Moreover, in the existing screen printing method, short circuits (short) or openings may appear on the screen during printing.

Embodiment 1

[0047] 15% by weight of methacrylic acid (MA): benzyl acrylate (BA): 2-hydroxyethyl (meth)acrylate (2-HEMA): methyl (meth)acrylate as an acrylate polymer resin (MMA) Polymer resin (weight average molecular weight: 25,000) polymerized in a weight ratio of 30:20:10:40, 10% by weight of M310 (supplied by Miwon Commercial Co., Ltd.) as a cross-linked oligomer: DPHA (supplied by Japan Chemical Co., Ltd.): U-108A (supplied by Shin-Nakamura Chemical Co., Ltd.) cross-linked oligomer mixed in a ratio of 1:2:1, 71% by weight as metal powder Silver and 2% by weight of an amino group-containing organic dispersant as a dispersant were mixed and stirred at room temperature, and finally, a desired paste composition for printing was prepared using a 3-roll mill.

Embodiment 2～3 and comparative example 1～2

[0049] Except that the composition shown in Table 1 below was used in Example 1, the same procedure as in Example 1 was performed to prepare a paste composition for printing.

[0050] The units used in Table 1 are % by weight.

[0051] Table 1

[0052]

[0053] Gravure offset printing was performed using the printing paste compositions prepared in Examples 1 to 3 and Comparative Example 1 or 2 to evaluate printing performance, minimum line width, and pattern directionality, and the results are shown in Table 2 below.

[0054] In the gravure offset printing, each of the paste compositions for printing prepared in Examples 1 to 3 and Comparative Example 1 or 2 was applied to a gravure panel, and the composition was uniformly applied thereon using a doctor blade. , and then transfer the composition on the intaglio panel to the covering (OFF process). Next, the pattern transferred to the cover is cured once using a UV lamp, and the pattern transferred to the cover is t...

Abstract

This invention provides paste composition for printing, which is particularly characterized by comprising a) 5 to 30 % by weight of an acrylate polymer resin; b) 5 to 30 % by weight of a cross-linking oligomer; c) 0.1 to 5 % by weight of a photopolymerization initiator; and d) 50 to 85 % by weight of a metal powder. The paste composition for printing in accordance with the invention is especially suitable for gravure offset printing capable of directly forming fine pattern, it can fundamentally solve retreatment problems of materials that occur during the manufacturing of electrodes of mesh filters for shielding electromagnetic waves or electrode pattern for plasma display panels using the prior photolithography methods and at the same time, it can satisfy a variety of the properties required as a paste composition each of which is required for printing process so that appropriate offset print performance can be exerted.

Description

technical field [0001] The present invention relates to a paste composition for printing, and more particularly to a paste composition for printing especially suitable for gravure offset printing capable of directly forming fine patterns, which can The problem of material reprocessing that occurs when the electrodes of the mesh filter for shielding electromagnetic waves or the electrode pattern for the plasma display panel is manufactured by engraving, and various properties required for the paste composition can be satisfied at the same time, among which Each is required by the printing process for proper offset performance. Background technique [0002] Recently, with increasing demands for large size, high density, high precision, and high reliability in display devices, various pattern processing technologies are being developed, and research is being conducted on a large number of patterns for forming patterns suitable for the various patterns. The composition of the f...
