Regarding.

紙等の記録媒体上に画像を形成する方法として、インクジェット記録方式が知られている。インクジェット記録方式は、インクの消費効率が高く、省資源性に優れており、単位記録あたりのインクのコストを低く抑えることが可能である。 An inkjet recording method is known as a method of forming an image on a recording medium such as paper. The inkjet recording method has high ink consumption efficiency and is excellent in resource saving, and it is possible to keep the cost of ink per unit recording low.

近年、紫外線硬化型インクを用いたインクジェット記録方式が注目されている。 In recent years, an inkjet recording method using an ultraviolet curable ink has attracted attention.

特許文献1には、a)1〜60質量%のアクリルアミド、b)0〜80質量%の単官能アクリレートモノマー、c)0〜10質量%の二官能アクリレートモノマー、d)0〜5質量%の三官能以上のアクリレートモノマー、e)0.1〜25質量%の光開始剤、f)0〜18質量%のアミンシナジスト、g)0〜5質量%のN−ビニル化合物、および0〜70質量%の水を含むインクが開示されている。 Patent Document 1 describes a) 1 to 60% by mass of acrylamide, b) 0 to 80% by mass of a monofunctional acrylate monomer, c) 0 to 10% by mass of a bifunctional acrylate monomer, and d) 0 to 5% by mass.

Ink containing mass% water is disclosed.
