The present invention provides an inkjet ink comprising: 6-35% by weight of NVC; 5-60% by weight of PEA; 15-35% by weight of a C8.12 alkane diol di(meth)acrylate; a radical photoinitiator; and a colorant, wherein the percentages by weight are based on the total weight of the ink. The present invention further provides an inkjet ink set wherein at least one of the inks in the set, preferably all of the inks in the set, is an inkjet ink as defined above. Furthermore, the present invention provides a method of inkjet printing comprising inkjet printing the inkjet ink or inkjet ink set as defined above onto a substrate and curing the ink.

Provided is an ink set including: a first ink that is white and contains water, hollow resin particles, and at least one organic solvent; and a second ink that contains water and at least one organic solvent and is to be applied on a first image formed with the first ink to form a second image, wherein an average thickness difference (A-B) between an average thickness (A) of the first image before the second ink is applied and an average thickness (B) of a white region in the first image after the second image is formed is 1 μm or greater but 3 μm or less.

A water-based ink set for ink-jet recording includes: a water-based yellow ink containing a yellow pigment, a resin dispersant, and water; a water-based magenta ink containing a magenta pigment, a resin dispersant, and water; a water-based cyan ink containing a cyan pigment, a resin dispersant, and water; and a water-based black ink containing self-dispersible carbon black and water. At least one water-based color ink selected from the group consisting of the water-based yellow ink, the water-based magenta ink, and the water-based cyan ink further contains a dye. The self-dispersible carbon black has an average particle size of 120 to 170 nm.

An image sheet capable of maintaining good image quality without a change in density or color in a low-density part of an image is provide. The image sheet for both transmitted light and reflected light includes: a base layer formed of a light-transmitting white resin film; a first image layer formed of a first color image formed on one surface of the base layer; a second image layer formed of a second white image formed on the first image layer so that a position of the same image as the first image is superimposed on the position of the first image; and a third image layer formed of a third color image formed on the second image layer so that a position of the same image as the first image is superimposed on the position of the first image.

An ink set includes an ink A including water, a first organic solvent, and a first pigment and an ink B including water, a second organic solvent, a second pigment, and a urethane resin particle. The first organic solvent includes at least one of N,N-dimethyl-β-buthoxy propionamide, N,N-dimethyl-β-methoxy propionamide, and 3-ethyl-3-hydroxymethyl oxetane and has a mixing solubility parameter A of 10.00 to less than 13.00 and the second organic solvent has a mixing solubility parameter B of 13.00 to 16.00.
