Abstract
Abstract The present invention provides a liquid composition containing a cationic fluorocarbon surfactant having a general formula [I] or [II] and a polymer compound in a solvent, and a liquid composition containing a cationic fluorocarbon surfactant having a general formula [III] and a polymer compound in a solvent: ##STR1## wherein Rf represents a fluorocarbon group in which at least some of the hydrogen atoms in an alkyl group having 4 to 12 carbon atoms are substituted by fluorine atoms, each of R 1 , R 2 , R 3 , R 4 , and R 5 represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms, HX represents a hydrohalogenic acid, and X⊖ represents a halogen anion; ##STR2## wherein n represents an integer from 4 to 12, and X⊖ represents a halogen anion. The present invention further provides an ink set, in which the above liquid composition is combined with one or more inks, a method of forming an image and apparatus for forming the image by applying the ink set and liquid composition.
