Abstract:
1. A liquid composition containing a liquid crystal polyester, comprising: (a) 15 to 40% by weight of a liquid crystal polyester including a repeating unit represented by the general formula (1), a repeating unit represented by the general formula (2), and a repeating unit represented by the general formula (3): wherein Ar 1 is a phenylene group, a naphthylene group, or a biphenylylene group; Ar 2 and Ar 3 each independently represents a phenylene group, a naphthylene group, a biphenylylene group, or a group represented by the general formula (4); X and Y each independently represents an oxygen atom or an imino group; Ar 4 and Ar 5 each independently represents a phenylene group or a naphthylene group; Z is an oxygen atom, a sulfur atom, a carbonyl group, a sulfonyl group, or an alkylidene group; and hydrogen atoms in Ar 1 , Ar 2 , or Ar 3 each independently can be substituted with a halogen atom, an alkyl group, or an aryl group; and (b) 60 to 85% by weight of a solvent containing N-methylpyrrolidone; wherein the liquid composition has a viscosity of 1.5 Pa·s or larger measured at 23° C. and the total of the liquid crystal polyester and the solvent is 100% by weight.
