Ink composition, inkjet recording method, printed material, and process for producing molded printed material

Synthetic Example 1

[0052]

[0053]The terminally iodinated telomer thus obtained is normally subjected to an appropriate terminal chemical modification such as one in Synthetic Example 2 below, to give fluoroaliphatic compounds. These compounds are further converted into desired monomer structures, and used in the production of a fluoroaliphatic group-containing polymer.

Synthetic Example 2

[0054]

[0055]As a monomer synthesized by the telomer method above, a monomer represented by Formula [TM-1] below is preferable.

[0056]In Formula [TM-1] above, T denotes one type of group selected from Group T below, Z denotes one type of group selected from Group Z below, and n denotes an integer of 0 to 20.

[0057]In Formula [TM-1] above, a compound in which the group denoted by Z is one type of group selected from Group Z′ below is particularly preferable since, due to it having an acryloyl group or a methacryloyl group at a molecular terminus, a polymer having in a side chain a group derived from the fluoroaliphatic compound is simply obtained from vinyl polymerization.

[0058]In the present invention, specific examples of the compound produced by the above-mentioned telomer method, which is suitable as a compound introduced into a side chain of the perfluoroalkyl group-containing polymer (compound having as main component monomer represented by Formula [TM-1] above), i

(b) Polymer having Structure Represented by Formula (I)

[0062]In the present invention, from the viewpoint of localization on the ink surface, the perfluoroalkyl group-containing polymer preferably has the constitution of Formula (I) below.

[0063]In Formula (I), R2 and R3 independently denote a hydrogen atom or an alkyl group having 1 to 4 carbons, Y denotes a polymer chain, X denotes a single bond or a divalent linking group (organic group), m denotes an integer of 0 or greater, and n denotes an integer of 1 or greater. When m is 2 or greater, functional groups on adjacent carbons (i.e. R2s or R3s bonded to adjacent carbons) may be bonded to form an aliphatic ring.

[0064]Among perfluoroalkyl group-containing polymers having the constitution represented by Formula (I) above, n in Formula (I) is preferably 1 to 10, more preferably 1 to 4, and particularly preferably 2 or 3.

[0065]That is, it has been found that in the present invention, with regard to the perfluoroa
