Abstract

To provide an inkjet ink composition that has excellent discharge stability and gives an ink image film having excellent substrate adhesion and film hardness, and an inkjet recording method employing the inkjet ink composition.
An inkjet ink composition comprises (Component A) a dendritic polymer compound having a weight-average molecular weight of 3,000 to 100,000 and having a constituent repeating unit represented by Formula (I); (Component B) a polymerization initiator; and (Component C) a radically polymerizable compound.

(In Formula (I), R 1 and R 2 independently denote a hydrogen atom or an alkyl group having 1 to 6 carbons, R 3 denotes an alkyl group having 1 to 12 carbons, and R 2 and R 3 may be bonded to form a ring structure.)

First claim

What is claimed is:

1. An inkjet ink composition comprising:
(Component A) a dendritic polymer compound having a weight-average molecular weight of 3,000 to 100,000 and having a constituent repeating unit represented by Formula (I);
(Component B) a polymerization initiator; and
(Component C) a radically polymerizable compound,

wherein R 1 and R 2 independently denote a…
