Abstract
Official abstract text for this publication.
In a resin for an active-energy-ray-curable ink containing a rosin-modified polyester resin, the rosin-modified polyester resin includes a reaction product of a material component containing rosins, a dibasic acid, and a polyol. The rosin-modified polyester resin has an ester bond in an amount of 5.20 mol/kg or more and 7.20 mol/kg or less. The rosin-modified polyester resin has an acid value of 1 mgKOH/g or more and 30 mgKOH/g or less. The rosin-modified polyester resin has a hydroxyl value of 1 mgKOH/g or more and 40 mgKOH/g or less.
First claim
Opening claim text (preview).
The invention claimed is: 1. A resin for an active-energy-ray-curable ink, the resin comprising a rosin-modified polyester resin, wherein the rosin-modified polyester resin includes a reaction product of a material component containing rosins, a dibasic acid, and a polyol, the rosin-modified polyester resin has an ester bond in an amount of 5.20 mol/kg or more and 7.20 mol/kg or less, the rosin-modified polyester resin has an acid value of 1 mgKOH/g or more and 30 mgKOH/g or less, and the rosin-modified polyester resin has a hydroxyl value of 1 mgKOH/g or more and 40 mgKOH/g or less. 2. The resin for an active-energy-ray-curable ink according to claim 1 , wherein the rosin-modified polyester resin has an ester bond in an amount of 5.30 mol/kg or more and 6.85 mol/kg or less, the rosin-modified polyester resin has an acid value of 1 mgKOH/g or more and 20 mg/g or less, and the rosin-modified polyester resin has a hydroxyl value of 1 mgKOH/g or more and 30 mg/g or less. 3. The resin for an active-energy-ray-curable ink according to claim 1 , wherein the polyol includes a dihydric alcohol, and a mole ratio (dihydric alcohol/rosins) of the dihydric alcohol to the rosins is 0.3 or more and 2.0 or less. 4. A composition for an active-energy-ray-curable ink, the composition comprising: the resin for an active-energy-ray-curable ink according to claim 1 ; and an active-energy-ray-curable monomer. 5. An active-energy-ray-curable ink comprising: the composition for an active-energy-ray-curable ink according to claim 4 ; and a pigment.
