Description

Non-display portion pattern composition

The present application claims the priority of the Korean Patent Application No. 10-2013-0081706, filed on Jan.
The present invention relates to compositions that form a non-display portion pattern.

Micropatterns for semiconductor circuit components and display devices such as LCDs, PDPs, or the like are formed via photolithography using photoresist. Photolithography has the advantage of obtaining the desired precision pattern. However, it also has many shortcomings. The disadvantages are that multiple processes are required, multiple materials are used to maximize the photoresist effect, and coatings or other processes require a considerable amount of Light resistance.
Therefore, in order to overcome the disadvantages of such photolithography as described above, a next generation process of micropattern formation, such as roll printing or inkjet printing, has been proposed in recent years.
A variety of methods include, for example, offset printing, inverse offset printing, roll-t-roll printing, or the like, which can be applied to micropattern formation via roller printing. It is also used in a wide range of applications, namely the composition of color filters (eg R (red), G (green) and B (blue) and black matrix (BM) patterns, thin film transistors (TFT) Or the electrode formation pattern of the plasma display panel (PDP), the lithography of the barrier material (pattern transfer), and the like.
Recently, a method of forming a non-display portion pattern by roller printing on a touch screen panel has been proposed.

Referring to Table 1 above, it was found that the coating film formed using each of the compositions for forming the non-display portion pattern according to Examples 1 to 4 performed well even after the film was exposed to a condition of a base or an acid or a remover. Adhesion to achieve excellent chemical resistance.
Referring to Fig. 2, it was found that the coating film formed using the composition prepared in Example 1 did not exhibit detachment of the lattice pattern after the acid resistance test, thereby achieving excellent chemical resistance.
Although the composition for forming a non-display portion pattern prepared in Example 5 contains an excess of a decane compound having an isocyanate group, it still exhibits excellent chemical resistance.
On the other hand, the coating film formed using each of the compositions for forming the non-display portion patterns according to Comparative Examples 1 and 2 had a reduced alkali resistance and a very poor acid resistance, respectively.
Referring to Fig. 3, it was found that the coating film formed using the composition prepared in Comparative Example 1 had low acid resistance and most of the pattern was detached.
