Photohardenable electrostatic master comprising an electrically conductive substrate, e.g., aluminized polyethylene terephthalate, bearing a layer of a photopolymer comprising an organic polymeric binder, compound having at least one ethylenically unsaturated group, photoinitiator and at least one organic electron acceptor or donor compound, e.g., the acceptor and donor having an oxidation potential of less than +2.5 eV and reduction potential larger than -3.0 eV, respectively. The photohardenable electrostatic master is used for electrostatic proofing, etc.

Process for producing negative or positive images from a photohardenable electrostatic master comprising an electrically conductive substrate bearing a photohardenable layer containing a photoinhibitor and a visible light sensitizer wherein the negative image (1) is prepared by (a) imagewise exposing to visible radiation, (b) charging electrostatically the master, (c) developing the charged image with an electrostatic toner, e.g., liquid electrostatic developer, and (d) transferring the toner image to a surface, e.g., paper. The positive image (2) is prepared by (a) imagewise exposing to ultraviolet radiation, (b) exposing overall to visible radiation followed by steps (b), (c) and (d) above. Multiple images can be prepared from the same master as well as color proofs using different color toners or developers and transferring in register over the original image.

An ink jet recording method for recording an image on a recording medium using a first liquid A containing a polymerizable or crosslinkable material, and a second liquid B having a different composition from the composition of the first liquid A, the method comprising: applying the second liquid B, in which a compound having a difference of an inorganicity/organicity ratio estimated from a structure of compound (I/O value) of 3 or less from the polymerizable or crosslinkable material is contained in a range of 50% by mass or more, onto the same area at which the image is to be formed by the first liquid A or a wider area than the area at which the image is to be formed by the first liquid A, of the recording medium which is impermeable or slowly-permeable; jetting the first liquid A onto the recording medium where the second liquid B has been applied so that at least a droplet a1 and a droplet a2 of the first liquid A have an overlap portion; and providing activation energy within 60 seconds of impact of each droplet of the first liquid A to cause polymerization of the polymerizable material or to cause crosslinking of the crosslinkable material.
