Abstract
Official abstract text for this publication.
The UV curable ink jet recording ink composition contains a thioxanthone-based photopolymerization initiator and a hindered amine compound. The dissolved oxygen content in the ink composition is 20 ppm or less.
First claim
Opening claim text (preview).
What is claimed is: 1. A UV curable ink jet recording ink composition comprising: a thioxanthone-based photopolymerization initiator; and a hindered amine compound, wherein the ink composition has an dissolved oxygen content is in the range of 5 to 20 ppm , wherein the hindered amine compound content is from 0.05 to 0.5% by mass relative to the total mass of the ink composition. 2. The UV curable ink jet recording ink composition according to claim 1 , wherein the thioxanthone-based photopolymerization initiator content is 0.5% to 4% by mass. 3. The UV curable ink jet recording ink composition according to claim 1 , wherein the hindered amine compound has a 2,2,6,6-tetramethylpiperidine-N-oxyl skeleton. 4. The UV curable ink jet recording ink composition according to claim 1 , wherein the thioxanthone-based photopolymerization initiator contains at least one compound selected from the group consisting of thioxanthone, diethylthioxanthone, isopropylthioxanthone, and chlorothioxanthone. 5. The UV curable ink jet recording ink composition according to claim 1 , wherein the thioxanthone-based photopolymerization initiator contains diethylthioxanthone. 6. The UV curable recording ink composition according to claim 1 , further containing an acylphosphine oxide-based photopolymerization initiator. 7. An ink container comprising: the UV curable ink jet recording ink composition as set forth in claim 1 ; and a member in contact with the ink composition. 8. An ink container comprising: the UV curable ink jet recording ink composition as set forth in claim 2 ; and a member in contact with the ink composition. 9. An ink container comprising: the UV curable ink jet recording ink composition as set forth in claim 3 ; and a member in contact with the ink composition. 10. An ink container comprising: the UV curable ink jet recording ink composition as set forth in claim 4 ; and a member in contact with the ink composition. 11. An ink container comprising: the UV curable ink jet recording ink composition as set forth in claim 5 ; and a member in contact with the ink composition. 12. An ink container comprising: the UV curable ink jet recording ink composition as set forth in claim 6 ; and a member in contact with the ink composition. 13. The ink container according to claim 7 , wherein the member is made of a material having an oxygen permeation rate of 5.0 cc·20 μm/(m 2 ·day·atm) or less at a temperature of 23° C. and a relative humidity of 65%. 14. An ink jet recording method using the UV curable ink jet recording ink composition as set forth in claim 1 . 15. An ink jet recording method using the UV curable ink jet recording ink composition as set forth in claim 2 . 16. An ink jet recording method using the UV curable ink jet recording ink composition as set forth in claim 3 . 17. An ink jet recording method using the UV curable ink jet recording ink composition as set forth in claim 4 . 18. An ink jet recording method using the UV curable ink jet recording ink composition as set forth in claim 5 .
