Description

Resin composition and touch screen panel comprising the same

The present invention relates to a resin composition and a touch screen panel comprising the same.

The touch screen panel is an input/output means of an electronic device that detects a user's touch position on a display screen and performs overall control of the electronic device, including display screen control, using the sensed information. The technical importance of such a touch screen panel is increasing due to the recent surge in demand for smartphones.

The method of the touch screen panel includes a resistive film method, a capacitive type method, an electromagnetic induction type method, and the like. Among them, the capacitive type is the most used, and this method uses the principle of detecting static electricity generated in the human body. The capacitive type method has the advantages of strong durability, good transmittance, and fast response time, but the touch screen panel implementing this uses a patterned conductive transparent electrode, and due to the difference in reflectance between the conductive layer and the base layer, As the electrode pattern is observed, visibility becomes a problem. That is, the ITO electrode pattern becomes more distinct due to the difference in reflectance between the base film and the ITO film, and thus there is a problem in that visibility is lowered.

Known methods for improving this include Korean Patent Application Laid-Open No. 2010-0008758, Korean Patent Application Laid-Open No. 2008-0068552, and Korean Patent Application Laid-Open No. 2012-0047828. These methods consist of two layers with different refractive indices and a conductive layer, and are laminated on both sides with a transparent adhesive. Although the problem of visibility has been solved to some extent, the manufacturing process is complicated and the manufacturing cost is high due to the use of multi-layered film materials. .

Recently, in order to solve this problem, an all-in-one (OGS, One Glass Solution) method in which a sensor is combined with a cover glass rather than a method using an existing ITO film has been introduced. This method is a method of forming electrodes by directly depositing ITO on the cover glass. It is considered as an innovative method of reducing the multi-step process that occurs when using an ITO film, thereby reducing related materials and process costs. It is a trend that is gradually expanding the application to large-area display products from the main application. However, even in this method, the above-described problem of visibility of the ITO pattern remains, and an appropriate method is required to solve it, and moreover, when depositing the ITO pattern or in a post-process for manufacturing a panel, exposure to a temperature close to 230 ~ 280 ℃ In some cases, materials with high heat resistance that can withstand such temperatures are required.

In order to solve the problems of the prior art described above, the present invention is to provide a resin composition that can solve the problem of visibility of the ITO pattern, and can manufacture a touch screen panel excellent in adhesion, heat resistance, and the like.

In the art, suitable for use as a material having a high refractive index may include nanoparticles such as ZnO, ZrO ₂ , TiO ₂ , ITO, and HfO ₂ . Their manufacturing methods can be roughly divided into two. The first method, the sol-gel method, is prepared through dehydration and condensation reactions in the presence of an acid or base using a precursor, and has the advantage of producing ultrafine particles of several nanometers. It is pointed out as a disadvantage that the thermal stability and water resistance of the coating film are deteriorated by being used in a non-existent state. In addition, the precursor is expensive and cannot be said to be a commercially useful method due to a decrease in molecular weight due to dehydration and condensation. Another method is to disperse and use nanoparticles, which is an industrially useful method. However, the problem in this method is that when the nanoparticles are not well dispersed, the particles are agglomerated and haze is generated, so that the transparency is lowered, and when the nanoparticles are coated, there is a problem that the coating is not uniformly performed.

In the case of using a commercially available dispersing agent in an effort to improve the dispersibility, a large amount is used because sufficient dispersibility cannot be ensured with a small amount. there is. In particular, in a composition requiring high refractive properties, a commercially available dispersant has a low refractive index of about 1.4, and thus its use is limited.
