ABSTRACT:
An object of the invention is to provide a polymerizable liquid-crystal composition for obtaining a liquid-crystal film having good adhesiveness to supporting substrates. A polymerizable liquid-crystal layer of controlled alignment can be formed from the polymerizable liquid-crystal composition, and when the polymerizable liquid-crystal composition is polymerized, it gives a liquid-crystal film.The polymerizable liquid-crystal composition of the invention contains a polymerizable liquid-crystal compound represented by Formula (1) and a organosilicon compound having a primary amino group.wherein W is hydrogen, alkyl, alkenyl, halogen, —CN or -(G-Sp)r-P; P is a polymerizable group; Sp is alkylene; G is a bonding group; and MG is a mesogenic group represented by Formula (2):wherein T1and T2are ringed group; G1is a bonding group; and f is an integer of 0 to 4. The symbols in these formulae are defined in detail in claim2.
