Provided is a maintenance liquid for inkjet printers, which comprises at least one of glycol ethers and glycol esters represented by the following general formulas (1) to (3), and 45 to 10 mg/L of dissolved oxygen:RCO(OR)OR&#x2003;&#x2003;General formula (1)RCO(OR)OCOR&#x2003;&#x2003;General formula (2)R(OR)OR&#x2003;&#x2003;General formula (3)

Maintenance liquid for inkjet printers

Provided is an active energy ray-curable inkjet ink comprising a pigment and polymerizable monomers that is superior in nozzle ejection stability, adhesiveness to recording medium and storage stability, wherein the polymerizable monomers comprise N-acryloyloxyethyl hexahydrophthalimide.

Active energy ray-curable inkjet ink composition

A display panel has a resin substrate and a printed layer formed on at least a part of the resin substrate through inkjet printing. The printed layer is formed from cured products of UV-curable inks each containing UV-curable monomers which are polymerized and cured by UV irradiation, and the printed layer has at least two such cured products having different pencil hardness values.

The present invention relates to an active energy beam-curable ink comprising polymerizable monomers, wherein relative to the total of all the polymerizable monomers, the polymerizable monomers comprise from 95 to 99.99% by weight of a monofunctional monomer and from 0.01 to 5% by weight of a polyfunctional monomer, and a cured film of thickness 10 &#x3bc;m formed using the active energy beam-curable ink exhibits a drawing ability exceeding 120% when stretched at a temperature of 170&#xb0; C. at a strain rate of 2/min.

Actinic radiation curable jet-printing ink

Disclosed is an active energy beam curable inkjet printing ink including a pigment, a compound containing two or more ethylenic double bonds, a compound containing one ethylenic double bond and having a molecular weight of 90 to 210, 2-benzyl-2-dimethylamino-1-(4-morpholinophenyl)-butanone-1 as a first initiator, and acylphosphine oxides as a second initiator. The ink has low viscosity, excellent photo-polymerizability, remarkably excellent curing property, good dispersion stability, causes no dissolution and swelling of ink contacting materials in a printer, and shows excellent discharge stability from nozzles, an excellent adherence property to a recording medium, excellent solvent resistance and water resistance.
