Abstract
An oil-based ink composition for inkjet recording capable of exhibiting desired properties of drying after print, rubfastness and re-solubility is achieved by performing solubilization on an acrylic resin which is not easily dissolved conventionally. The oil-based ink composition for inkjet printing comprises glycol ether dialkyl ethers as a prime solvent; and an acrylic resin that results from solution polymerization in a solvent of the glycol ether dialkyl ethers by use of a radical polymerization initiator.
Claims14
A composition comprising:
- a glycol ether dialkyl ether as a prime solvent;
- and
- a first reaction product having a structure in which a glycol ether dialkyl ether is bonded to a terminal of an acrylic resin,
- wherein the first reaction product results from solution polymerization of a free radical polymerizable acrylic monomer in a solvent of the glycol ether dialkyl ether by use of a radical polymerization initiator, and
- wherein the composition is an oil-based inkjet ink composition.
A method of producing a composition comprising:
- providing a glycol ether dialkyl ether;
- providing a first reaction product having a structure in which a glycol ether dialkyl ether is bonded to a terminal of an acrylic resin, wherein the first reaction product results from solution polymerization of a free radical polymerizable acrylic monomer in a solvent of the glycol ether dialkyl ether by use of a radical polymerization initiator, and
- blending the glycol ether dialkyl ether and the first reaction product,
- wherein the composition is an oil-based inkjet ink composition.
