Problems solved by technology

However, active energy ray-curable ink compositions need to use a large amount of monomers and oligomers as their components, so it is difficult to use a large amount of biomass-derived components. Instead of including the ratio of components derived from biomass, environmental response characteristics such as recycling suitability and energy-saving measures are used as indicators

preparation example Construction

[0116]

[0117] Moreover, the preparation method of the said active energy ray curable ink composition is also one of this invention. The method for producing an ink composition of the present invention is a method for producing an active energy ray-curable ink composition comprising a compound having an ethylenically unsaturated bond, a specific resin, a specific liquid component, and a photopolymerization initiator, and is characterized in that it comprises A step of preparing a varnish by dissolving the specific resin in the heated specific liquid component, wherein the specific resin is selected from rosin-modified phenolic resins, rosin-modified maleic acid resins, rosin-modified alkyd resins, natural asphalt resins, and asphalt resins. At least one of the resins, the above-mentioned specific liquid component does not have an ethylenically unsaturated bond, and the solubility parameter sp value obtained by the cloud point titration method is 9.0 (cal / cm 3 ) 1 / 2 More th...

Embodiment

[0126] Hereinafter, although an Example is shown and this invention is demonstrated more concretely, this invention is not limited to the following Example at all. In addition, in the following description, unless otherwise specified, "%" means "mass %", and "part" means a mass part. In addition, the unit of sp value is (cal / cm 3 ) 1 / 2 .

[0127] [Preparation of Varnish 1]

[0128] Varnish 1 was obtained by heating and dissolving a mixture of 40 parts by mass of rosin-modified phenolic resin (sp value 8.83) and 60 parts by mass of epoxidized soybean oil at 200°C for 60 minutes.

[0129] [Preparation of Varnish 2]

[0130] Varnish 2 was obtained by the same procedure as Varnish 1 except having used castor oil instead of epoxidized soybean oil.

[0131] [Preparation of Varnish 3]

[0132] Varnish 3 was prepared in the same procedure as Varnish 1 except that trimethylolpropane triacrylate (TMPTA) was used instead of epoxidized soybean oil, but the resin was not dissolved in...

Abstract

The invention provides an active energy ray-curable ink composition which has an increased content of a biomass-derived raw material and contains a material, such as a rosin-modified phenolic resin, having high pigment dispersibility. This active energy ray-curable ink composition contains a compound having an ethylenically unsaturated bond, a specific resin, and a specific liquid component. The specific resin is at least one selected from the group consisting of rosin-modified phenolic resins, rosin-modified maleic acid resins, rosin-modified alkyd resins, gilsonite resins, and asphalt resins. The specific liquid component is an animal- or plant-derived fat / oil or a modified product thereof which has no ethylenically unsaturated bond and has a solubility parameter sp value (hereinafter referred to as sp value) of 9.0 (cal / cm<3>)1 / 2 or more and less than 11.0 (cal / cm<3>)1 / 2 as determined by the cloud-point titration method.

Description

technical field [0001] The present invention relates to an active energy ray-curable ink composition, a method for producing the same, and a method for producing a printed matter using the composition. Background technique [0002] In the case of printing using an ink composition, various printing methods are appropriately selected according to the material, shape, etc. of an object to be printed, and an ink composition having appropriate properties is selected according to the printing method. For example, for flat printing paper, an offset printing method using lithography is selected, and an offset printing ink composition containing vegetable oil and mineral oil with high viscosity is used; In the flexographic printing method of the rubber letterpress, a water-based ink composition for flexographic printing with extremely high fluidity, etc. are used. In addition, it is also known to perform printing by appropriately selecting various printing methods such as gravure pr...
