Abstract
Official abstract text for this publication.
Provided is a ultraviolet-curable liquid developer containing a cationically polymerizable liquid monomer, a photoinitiator, and a toner particle, wherein the cationically polymerizable liquid monomer contains a vinyl ether compound; defining A as the molar average number of functional groups for the vinyl ether compound and B as the molar average molecular weight of the vinyl ether compound, A and B satisfy the relationship A/B×1,000≧8.5; and the photoinitiator contains a specific compound.
First claim
Opening claim text (preview).
What is claimed is: 1 . An ultraviolet-curable liquid developer comprising a cationically polymerizable liquid monomer, a photoinitiator, and a toner particle, wherein the cationically polymerizable liquid monomer contains a vinyl ether compound; defining A as the molar average number of functional groups for the vinyl ether compound and B as the molar average molecular weight of the vinyl ether compound, A and B satisfy the relationship A/B×1,000≧8.5; and the photoinitiator contains a compound with the following formula (1): wherein R 1 and R 2 are bonded to each other to form a ring structure; x represents an integer that is at least 1 and not more than 8; and y represents an integer that is at least 3 and not more 17. 2 . The ultraviolet-curable liquid developer according to claim 1 , wherein A and B satisfy the relationship A/B×1,000≧9.5. 3 . The ultraviolet-curable liquid developer according to claim 1 , wherein the content of the compound with formula (1) is at least 0.05 mass parts and not more than 1.00 mass part per 100 mass parts of the cationically polymerizable liquid monomer. 4 . The ultraviolet-curable liquid developer according to claim 1 , wherein the compound with formula (1) is a compound with the following formula (2): wherein x represents an integer that is at least 1 and not more than 8; y represents an integer that is at least 3 and not more than 17; R 3 and R 4 are independently selected from an alkyl group, alkyloxy group, alkylthio group, aryl group, aryloxy group, and arylthio group; o and p each independently represent an integer that is at least 0 and not more than 3; when o is equal to or greater than 2, a plurality of R 3 may be bonded to each other to form a ring structure; when p is equal to or greater than 2, a plurality of R 4 may be bonded to each other to form a ring structure; and an R 3 and R 4 may be bonded to each other to form a ring structure. 5 . The ultraviolet-curable liquid developer according to claim 1 , further comprising a photopolymerization sensitizer, wherein the photopolymerization sensitizer contains a thioxanthone-type compound or an anthracene-type compound. 6 . The ultraviolet-curable liquid developer according to claim 5 , further comprising a photopolymerization sensitizing aid, wherein the photopolymerization sensitizing aid contains a naphthalene-type compound.
