An object of the invention is to provide a water-based lithographic printing method that is excellent in printing quality and environmental aspects. The invention concerns a method of producing a printed material, including the steps of: allowing a water-based ink to adhere to a surface of a heat sensitive layer of a lithographic printing plate having a surface on which an ink repelling layer and the heat sensitive layer exist; and transferring the adhering water-based ink directly or via a blanket to a printing substrate.

A thermo-responsive shear-thinning photo-curable composition comprises water, a linear amphiphilic polyether ABA triblock copolymer comprising at least one pendent ene group (*—CH═CH.sub.2) capable of undergoing a thiol-ene reaction, a water-soluble crosslinking agent comprising two or more methylenethiol groups (*—CH.sub.2SH), and a photoinitiator. Under non-shear conditions and a triblock copolymer concentration suitable for direct-write printing, the composition is a viscoelastic solid (hydrogel) at a temperature of about 15° C. to about 45° C., and is a free-flowing liquid (sol) between 0° C. and about 10° C. The hydrogel form can be shear-thinned at about 15° C. to about 45° C. to form a sol suitable for a direct-write printer using an extruding print-head. The compositions covalently crosslink when flood-exposed to ultraviolet radiation. The compositions have utility in forming three-dimensional scaffolds for growing living cells.

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.

Provided is an active energy ray-curable inkjet ink with high productivity which has the same quality level as the conventional printing and which contains an isoindoline-based pigment having a specific electric conductance, which is measured according to DIN ISO 787/14, of 150 μS/cm or less.
