Abstract

An object is to provide an ink composition for inkjet printing that permits inkjet printing, particularly on metal surfaces, wherein such ink composition possesses sufficiently high adhesion and heat resistance with respect to metal surfaces. As a means for achieving the object, a photocurable inkjet printing ink composition is provided, which contains, relative to the entire ink composition, 0.1 percent by mass or more of an acid-modified acrylic monomer and 10 to 30 percent by mass of a monofunctional monomer with a Tg of 100° C. or above, wherein the monofunctional monomer accounts for 80 percent by mass or more of all monomers.

First claim

What is claimed is:

1. A photocurable inkjet printing ink composition, containing, relative to an entire ink composition:
0.1 percent by mass or more of an acid-modified acrylic monomer; and
10 to 30 percent by mass of Ra monofunctional monomer(s) each having a Tg (glass transition temperature) of 100° C. or above;
wherein all monofunctional monomer(s), including the all monofunctional monomer(s) each having a Tg of 100° C. or above, account(s) for 80 percent by mass or more of all monomer(s) contained in the entire ink composition, and
the all monofunctional monomer(s) each having a Tg of 100° C. or above is/are one or more monofunctional monomers selected from the group consisting of acryloyl morpholine, methyl methacrylate, acrylamide, acrylic acid, dicyclopentanyl methacrylate, and 1-adamantyl methacrylate.

2. The photocurable inkjet printing ink composition according to claim 1 , wherein each monofunctional monomer with a Tg of 100° C. or above is a monofunctional monomer with a Tg of 120° C. or above.
