A liquid ejection device includes a storage section storing a nanoimprinting liquid and also includes an ejection port which communicates with the storage section and which ejects the nanoimprinting liquid. The storage section contains a sorption medium that adsorbs or absorbs at least one selected from the group consisting of particles, metal ions, and water. The sorption tedium is not ejected from the ejection port when the nanoimprinting liquid is ejected from the ejection port.

A photo-curable ink contains an oil-based liquid containing a polymerizable compound and a photopolymerization initiator, and an aqueous liquid containing water. When the photo-curable ink is stirred at a rotational speed of 15000 rpm or more for 3 minutes and then allowed to stand at 25&#xb0; C. for one hour or more, droplets formed with the aqueous liquid are dispersed in the oil-based liquid without layer separation between the oil-based liquid and the aqueous liquid.

In nanoimprinting processes, photo-cured products often separate from the substrate and stick to the mold due to insufficient adhesion between the photo-cured product and the substrate. This causes a defect of pattern separation. An adhesion layer composition used for forming an adhesion layer between a substrate and a photocurable composition includes a compound (A) having at least two functional groups, and a solvent (B). The functional groups include at least one functional group capable of being bound to the substrate, selected from the group consisting of hydroxy, carboxy, thiol, amino, epoxy, and (blocked) isocyanate, and at least one hydrogen donating group as a functional group capable of being bound to the photocurable composition.
