Description of the invention (3 acrylate, trimethylolpropane tri(meth) acrylate, pentaerythritol tetra (meth) acrylate, dipentaerythritol penta (meth) acrylate, pentaerythritol VI ( Methyl) acrylate, etc. In the photosensitive resin mixture of the prior art, the crosslinking compound is only distributed in the resin for the binder of the mixture, and when it is exposed to a kind of ultraviolet light such as ultraviolet rays, cross-linking occurs. Reacting to form a network structure' to prevent the alkaline soluble resin from being dissolved by the developer during the development process, However, it plays a role of leaving the image on the substrate. However, the difference in solubility between the exposed and unexposed areas of the existing photosensitive resin mixture is not large enough, and the resin which is actually retained during the development process has a resin. Some of them are dissolved by the developing solution, so that it is difficult to obtain an intended micro-pattern shape under most of the mud. On the other hand, in order to prevent this phenomenon, when the cross-linking compound is excessively used, not only the surface hardness after exposure is caused. It is degraded to detract from the nature of the process, and the yield is also reduced with the increase in the amount of exposure that promotes a sufficient cross-linking reaction. In addition, in this case, the solubility of the unexposed area is also deteriorated to reduce the disadvantage of resolution. SUMMARY OF THE INVENTION An object of the present invention is to provide a photosensitive resin having a chemical bond between a binder resin and a crosslinking compound in an exposed region during an exposure process, and a resin chain between the binders. The chemical bond maximizes the difference in solubility between the exposed and unexposed areas during the development process, thus providing superior resolution. Moreover, it can reduce the consumption of the cross-linking compound, minimize the necessary ultraviolet radiation, and solve the aforementioned problems, so as to have various process benefits and superior film properties. 297 mm) -------- ----- --------Set---------Line one* (Please read the phonetic transcription on the back?

[Example 7] The mixture shown in the following Table 7 was used to prepare a photosensitive resin mixture. Unlike the foregoing examples, the photosensitive resin mixture is formulated by not synthesizing the resin for the binder, but by putting together the starting material and the composition including the photosensitive resin mixture of this Example 7.

It is also known that the thickness of the film pattern is equivalent to 38 (7) when the exposure amount is 200 mJ/crn2, and the line width and The gap is equivalent to 10 μm, so that a clearer and more detailed pattern cannot be obtained compared to the results obtained in accordance with the examples of the present invention. Therefore, although the present invention applies less exposure, it uses self-curing. Adhesive tree The photosensitive resin mixture formed can obtain a clearer and more detailed pattern than the existing various mixtures, thereby shortening the time of the ultraviolet irradiation process, thereby providing a photosensitive resin mixture having various processing benefits, excellent resolution and film properties.
