[Industrial Application Field] The present invention relates to a photosensitive polymer paste containing polyvinyl alcohol as a main component. [Prior Art] FIG. 1 is a sectional view showing the main parts of a beam index tube. In the figure, 1 is a face plate made of a flat glass plate. A carbon stripe bl is formed on this face plate 1, and red, green and blue color fluorescent stripes R, G and B are successively formed therebetween. Further, an aluminum (Al) film 2 as a metal bag is formed on the color fluorescent stripes R, G, B, and an index fluorescent stripe ID is formed on the aluminum (Al) film 2 as a metal bag.
is formed. Further, 3 is a funnel, which is sealed at the end of the face plate 1 with a frit 4. In such a cathode ray tube, the carbon stripe bl is formed, for example, in the process shown in FIG. First, as shown in FIG. 1A, a photosensitive polymer paste 5 containing polyvinyl alcohol (PVA) as a main component is printed and coated on the face plate 1. As shown in FIG. Next, as shown in Figure B, the portion of the photosensitive polymer paste 5 where the PVA stripes are to be formed is exposed to ultraviolet light 7 through a photomask 6 to harden that portion. Next, as shown in Figure C, development is performed to form PVA stripes 8. Next, as shown in Figure D, carbon 9 is applied. Next, as shown in Figure E, the PVA stripe 8 is peeled off and the carbon 9 thereon is removed to form a carbon stripe bl. To form PVA stripe 8 in this process,
The reason why it is applied by a printing method rather than a spin coating method using slurry is that if the face plate 1 is flat and does not have a skirt and is applied by a spin coating method,
This is because there is a lot of slurry loss, and the slurry also adheres to the back surface and the exposure reference surface, which requires removal treatment. [Problems to be solved by the invention] However, when the photosensitive polymer paste 5 containing PVA as the main component is applied by the printing method, bubbles are more likely to be generated than by the spin coating method using slurry, and the bubbles in the PVA stripes 8 are There was a problem that the carbon stripe BL was not formed correctly when carbon 9 was applied and adjacent stripes were connected. It should be noted that these bubbles cannot be completely eliminated by methods such as leveling, which involves placing them in a parallel state and leveling them naturally. [Means for Solving the Problems] In order to solve the above-mentioned problems, the photosensitive polymer paste of the present invention uses PVA as the main component, which is the same as the conventional one, but it also has an interface with a high antifoaming and leveling effect. It contains an activator, namely polyoxyethylene sorbitan fatty acid ester, in a predetermined weight ratio. [Function] Due to the antifoaming and leveling effect of polyoxyethylene sorbitan fatty acid ester, there is little generation of bubbles even when applied by the printing method, and the quality of the printed coating surface is stable. [Examples] Examples of the present invention will be described below.

According to the present invention described above, due to the antifoaming and leveling effect of polyoxyethylene sorbitan fatty acid ester, even when this photosensitive polymer paste is applied by printing, there is little generation of bubbles, and the quality of the printed application surface is stable. become Thus, for example, bubbles in PVA stripes are reduced and carbon stripes are formed correctly. Further, according to the present invention, there is an advantage that the leveling process can be omitted due to the leveling effect of polyoxyethylene sorbitan fatty acid ester.
