Abstract

The present invention provides an oxetane compound represented by the following formula (1), and a active energy ray-curable composition including the oxetane compound as a polymerizable monomer. In formula (1), R¹¹ to R¹⁵ each independently represents a hydrogen atom or an alkyl group; R²¹ to R²⁴ each independently represents a hydrogen atom, an alkyl group, an alkoxy group or a halogen atom; R represents an alkyl group including a partial structure selected from an oxirane ring, an oxetane ring or a vinyl ether and having from 3 to 10 carbon atoms, or a vinyl group; and any adjacent groups among R²¹ to R²⁴ and R may be bonded to each other to form a ring structure

Claims

1. An oxetane compound represented by the following formula (1):

2. The oxetane compound of claim 1, wherein, in formula (1), R is an alkyl group including an oxirane ring as a partial structure and having from 3 to 10 carbon atoms.

3. The oxetane compound of claim 1, wherein, in formula (1), R¹¹, R¹² and R¹⁵ are each a hydrogen atom.

4. The oxetane compound of claim 1, wherein, in formula (1), R²¹ to R²⁴ are each a hydrogen atom;

or three of R²¹ to R²⁴ are a hydrogen atom and one of R²¹ to R²⁴ is an alkoxy group;

or two of R²¹ to R²⁴ are a hydrogen atom and two of R²¹ to R²⁴ are an alkoxy group.

5. An active energy ray-curable composition comprising the oxetane compound of claim 1 as a polymerizable monomer.

6. The active energy ray-curable composition of claim 5, wherein the content of the oxetane compound represented by formula (1) is from 10% by mass to 30% by mass with respect to a total mass of polymerizable monomers included in the active energy ray-curable composition.

7. An active energy ray-curable ink composition comprising the active energy ray-curable composition of claim 5.

8. The active energy ray-curable ink composition of claim 7, wherein the ink composition is an ink composition for inkjet recording.

9. An inkjet recording method comprising:

jetting the active energy ray-curable ink composition of claim 7 on to a recording medium using an inkjet recording device; and

curing the ink composition by irradiating the jetted ink composition with active radiation.
