Problems solved by technology

[0004] Furthermore, as the amount of conductive metals and black pigments used in the preparation of electrodes (especially, bus electrodes) increases, blocking phenomena such as reflection or absorption of ultraviolet (UV) light are extremely detrimental to UV exposure in the desired shape, so that curing occurs Occurs in areas close to the surface of the electrode layer rather than deep in the electrode layer
This disadvantage leads to severe undercut and poor workability during development

preparation Embodiment 1

[0048] Preparation Example 1: Preparation of Organic Binder

[0049] A stirrer, a thermocouple connected to a reaction controller, a condenser, and a nitrogen gas supply tube were connected to a 1 L four-necked flask. 28.46 g of polypropylene glycol (PPG, molecular weight: 1000 g / mol), 0.27 g of 1,4-butanediol, and 6.58 g of dimethylolpropionic acid were put into a reaction flask, which was heated to 85° C., Simultaneously, nitrogen gas was supplied at 10 cc / min. A solution (10% concentration) prepared by dissolving 0.6 g (10% concentration) of a tin catalyst (dibutyltin dilaurate, Aldrich Co., Ltd.) in toluene, 20.70 g of isophorone diisocyanate and 1.92 g of cyclohexyl diisocyanate trimer (Desmodur N3300, Bayer Co., Ltd.) was added to the reaction flask at 70° C. so that the equivalent weight of isocyanate became 2770 or more. The temperature of the resulting mixture was lowered to 75° C., 3.11 g of 2-hydroxyethyl (meth)acrylate was added to the flask, and the resulting mi...

[0050] Preparation Example 2: Preparation of Organic Binder

[0051] Urethane (meth)acrylate resin was prepared in the same manner as in Preparation Example 1, except that, in this example, 28.15 g of PPG, 0.26 g of 1,4-butanediol, and 6.5 g of dimethylol were used. Propionic acid, 21.55 grams of isophorone diisocyanate and 4.26 grams of 2-hydroxyethyl methacrylate, no cyclohexyl diisocyanate trimer was used. The acid value of the obtained resin in a solid state was 45 mgKOH / g.

Abstract

The invention discloses an electrode slurry composition and a plasma display panel electrode made of the same. The composition comprises conductive material, an organic binder, glass dust, a cross-linking agent, and a trigger. Based on the total weight of the composition, the organic binder comprises 15 to 35%, by weight, of polyurethane (methyl) acrylate resin. The composition can improve cohesiveness, without forming undercut, and reduce hemming after baking.

Description

technical field [0001] The invention relates to an electrode paste composition and a plasma display panel electrode prepared by using the composition. More particularly, the present invention relates to a kind of electrode paste composition, and this composition comprises a certain amount of urethane (meth)acrylate as organic binder, therefore can improve cohesion without forming undercut (undercut), And reduce curling after baking, and a plasma display panel electrode prepared by using the electrode paste. Background technique [0002] In order to make the photosensitive conductive paste have high conductivity, the conductive material should be prepared at high concentration. However, the conductive material prepared at a high concentration deteriorates light transmission or adhesion between the pattern and the substrate, making it difficult to obtain a fixed pattern. Therefore, in order to realize a thin line having a width of 50 μm or less while protecting high conducti...
