摘要:
A photosensitive material and comprises a photosensitive and heat-developable element and a polymer, and is capable of being endowed with stickness by a change of pH value or being subjected to exposure and heating. An image formation process comprises the steps of subjecting to imagewise exposure the photosensitive material, heating the photosensitive material, electrifying the photosensitive material, and transferring the iamgewise exposed or unexposed portion of the photosensitive material. The photosensitive and heat-developable element comprises a least a photosensitive silver salt and a reducing agent and the polymer has a cross-linked structure.

A printing process using an ink which is substantially non-adhesive but can be imparted with an adhesiveness when subjected to a pH change. In the printing process, the ink is subjected to a pH change to be provided with an adhesiveness to a desired depth, and the resultant adhesive ink is supplied to a printing plate having a pattern of ink receptibility to form thereon an ink pattern corresponding to the ink receptibility pattern. The ink pattern is then transferred to a transfer-receiving medium such as plain paper to form thereon a recorded image. In the above-mentioned printing process, a uniform thin ink layer can be supplied to the printing plate by chemically regulating the amount of the ink to be supplied.

A photosensitive material comprises a photosensitive composition comprising a photosensitive and heat-developable element and a photopolymerizable element. An imagewise unexposed area on the material is polymerized by imagewise exposure, heating and whole areal exposure. The photosensitive and heat-developable element comprises at least a photosensitive silver halide, an organic silver salt and a reducing agent of the formula ##STR1## The photopolymerizable element comprises at least a polymerizable polymer precursor and a photopolymerization initiator. An image forming method comprises the steps; subjecting a photosensitive material in the same layer to imagewise exposure and heating to form an image; and subjecting the resultant photosensitive material to whole areal exposure to polymerize and imagewise unexposed or exposed area thereof.

A process for development comprises arranging an electrostatic image bearing member having electrostatic images on the surface and a developer carrying member at a predetermined space, an insulating magnetic developer containing 10-50% by weight of magnetic toner particles 20-35 microns in size being carried on the developer carrying member in a thickness thinner than the predetermined space, and transferring the insulating magnetic developer to the electrostatic image bearing member in the presence of a magnetic field.According to this process for development, there can be produced developed images of high fidelity, high density and high resolution and free from fog.
摘要:
A layered ruthenic acid compound is converted to a protonic layered ruthenic acid hydrate, which is then converted to a layered alkylammonium-ruthenic acid intercalation compound to obtain a colloid containing ruthenic acid nanosheets having a thickness of 1 nm or smaller. Thereby, a ruthenic acid nanosheet is obtained.
