Clear inks are prone to heat-induced micro-gelling that can cause their storage stability to drop, and micro-gelling may also occur in clear inks with the passage of time, in which case their inkjet discharge property may drop. As a solution, a photocurable clear ink composition for inkjet printing is provided, which contains a photopolymerizable compound, a photopolymerization initiator, and an inorganic filler of 1 to 200 nm in average grain size accounting for 0.05 to 5.0 percent by mass in the composition, and whose visible light transmission factor is 30% or higher.

Described herein is an electrophotographic ink composition comprising: a first resin comprising a copolymer of an alkylene monomer and a monomer selected from acrylic acid and methacrylic acid; and a second resin comprising a condensation product of polyvinyl alcohol with an aldehyde. Also described herein is a method of producing the electrophotographic ink composition and a printed substrate produced by printing the electrophotographic ink composition.
