摘要:
A method of printing in which a solid ink composition is melted and ejected from a small orifice in the form of small drops directed towards a substrate on which an image is to be formed, characterized in that the solid ink composition comprises either a solution or a dispersion of a dye or a finely divided pigment in a halogenated hydrocarbon having a melting point of at least 50.degree. C. ("Ink A"), or a colored condensation polymer obtained by reacting a polymerizable lactone or a hydroxyalkanoic acid with a dye containing at least one active hydrogen atom ("Ink B").
