An ink for ink-jet printing, a cured film obtained by the ink, an ink coating method using the ink, a cured film forming method using the coating method, an electronic circuit board containing the cured film formed by the cured film forming method, and an electronic part containing the circuit board are provided to improve precision and the adhesion to a substrate. An ink for ink-jet printing comprises a fluorine-containing compound which is a fluorosilsesquioxane having a C1-C100 organic group. Preferably the fluorine-containing compound is represented by the formula 3, wherein Rg is a single bond, or a C1-C20 alkylene group whose methylene can be substituted with O; Rf^1 to Rf^7 are independently a C1-C20 linear or branched fluoroalkyl group whose methylene can be substituted with O, a C6-C20 fluoroaryl group whose H can be substituted with F or CF3, a C7-C20 fluoroarylalkyl group whose H can be substituted with F or CF3, a C1-C20 liner or branched fluorine-free alkyl group whose methylene can be substituted with O, a C6-C20 fluorine-free aryl group, or a C7-C20 fluorine-free arylalkyl group, and at least one of Rf^1 to Rf^7 is a fluoroalkyl group, a fluoroaryl group or a fluorarylalkyl group; and R is H or a C1-C100 organic group.
