Kind Code:
A1
Abstract:
A liquid stripper composition for liquid-crystal alignment films which comprises water and, incorporated therein, an inorganic alkali compound [A] such as potassium hydroxide, a C6-12 fatty acid [B], and an amino alcohol [C] having a boiling point of 150°C or higher, such as diethanolamine or triethanolamine, the amounts of the compound [A] and the acid [B] being 5-25 wt.% and 3-30 wt.%, respectively, based on the composition (provided that the total amount of the compound [A], fatty acid [B], and amino alcohol [C] is 9-60 wt.% based on the composition). The composition has a degree of [B]/[A] neutralization of 10-70%. This liquid stripper composition for alignment films has excellent stripping properties.
