Patent ID: 7858670

Claim:
A photosensitive inkjet ink comprising: a photo-acid generating agent; pigment; and an organic dispersion medium comprising at least one oxetane compound, at least one vinyl ether compound represented by formula (1) and at least one oxirane compound, said at least one oxetane compound comprising a monofunctional oxetane, said monofunctional oxetane being 3-ethyl-3-(phenoxymethyl) oxetane and being present in an amount of 20 to 60% by weight based on a total weight of the organic dispersion medium, the vinyl ether compound being present in an amount of 30% or more based on a total weight of the organic dispersion medium, and the oxirane compound being present in an amount of 30% or less based on a total weight of the organic dispersion medium: R 11 —R 12 —(R 11 ) p (1) wherein, R 11 is selected from the group consisting of a vinyl ether group, an atomic group having a vinyl ether group, an alkoxy group, an ether group and a hydroxyl group, at least one of the R 11 s being a vinyl ether group or an atomic group having a vinyl ether group; R 12 is a (p+1)-valent group having a substituted or unsubstituted cyclic skeleton containing an oxygen atom as a ring-constituting atom; and p is a positive integer including zero.
