PHOTOCURABLE INKJET INK AND IMAGE FORMING METHOD

摘要

An object of the present invention is to provide a photocurable inkjet ink having favorable discharge stability and a reduced odor. The photocurable inkjet ink of the present invention contains a photopolymerizable compound, a photopolymerization initiator, and a gelling agent; the content of the gelling agent is 0.5 mass % or more to 10 mass % or less based on the photocurable inkjet ink; and the photocurable inkjet ink further contains 10 mass ppm or more to 100 mass ppm or less of the compound which has a molecular weight of 200 or less and which contains a hydrophobic moiety having four or more carbon atoms Sbased on the photocurable inkjet ink.

主权项

1. A photocurable inkjet ink comprising a photopolymerizable compound, a photopolymerization initiator, and a gelling agent,
wherein: a content of the gelling agent is 0.5 mass % or more to 10 mass % or less based on the photocurable inkjet ink, and the photocurable inkjet ink further comprises 10 mass ppm or more to 100 mass ppm or less of a low molecular weight compound which has a molecular weight of 200 or less and which contains a hydrophobic group having four or more carbon atoms (provided that the low molecular weight compound is different from the photopolymerizable compound) based on the photocurable inkjet ink.
