摘要： The present invention provides a composition for forming a liquid crystal alignment film, which comprises a photoreactive polymer including a multicyclic compound having a photoreactive group on a main chain thereof. The present invention also provides a liquid crystal alignment film produced using the composition, and a liquid crystal display including the liquid crystal alignment film. The photoreactive polymer including the multicyclic compound on the main chain thereof has a high glass transition temperature, thus thermal stability is excellent. Since lattice vacancy is relatively large, the photoreactive group is capable of moving relatively freely in the main chain of the polymer, thus it is possible to improve a slow photoreaction rate, which is considered a disadvantage of a conventional polymer material.

摘要： Polyimide or a precursor thereof expressed by Chemical Formula 1 or 2 and a photosensitive organic insulator composition having the same are disclosed. The polyimide or the precursor thereof is prepared from diamine including polyalkyleneoxide.
The use of the photosensitive organic insulator composition can allow for low temperature curing and shorten a curing time, form a low taper angle, and implement a high sensitivity and high residual film. Also, since the photosensitive organic insulator composition, as a positive photosensitive composition, has excellent solubility with respect to an alkali solution of an exposed portion, the generation of impurity can be minimized.

摘要： The present invention relates to surface-coated positive electrode active material particles and a secondary battery including the same, and specifically, it provides surface-coated positive electrode active material particles including positive electrode active material particles and a coating layer applied on a surface of the positive electrode active material particles, wherein the coating layer includes a polyimide comprising one or more structures selected from the group consisting of pyrrole, aniline, and carbazole. The surface-coated positive electrode active material particles according to the present invention includes a coating layer including a polyimide and metal ions; and since a direct contact between the positive electrode active material particles and an electrolyte can be prevented, a side reaction therebetween can be inhibited, and both excellent lithium ion mobility and excellent electron conductivity can be exhibited. Accordingly, a secondary battery with improved battery life and cycle characteristics at high-voltage and high-temperature conditions can be obtained.
