A method of recording images on a radiation sensitive material comprising forming a layer of a radiation sensitive material comprised of a heterogeneous mixture of substances. At least one of the substances of the heterogeneous mixture serves as a binder capable of converting its states of aggregation in the mixture under the action of the intrinsic or reflected radiation obtainable from the object being recorded. Another substance of the heterogeneous mixture, in the form of particles, is capable of interacting with a force field. The layer is introduced in a force field and an image of the object being recorded is projeced on that layer. The produced image is fixed by converting the state of aggregation of the heterogeneous mixture. The proposed method makes it possible to record images in any spectral range of the intrinsic and reflected radiation of the object. Images of any objects can be recorded on that layer containing no silver halides.

A method of recording images of a radiation sensitive material comprising the steps of: forming a layer of radiation sensitive material comprised of a heterogeneous mixture of substances, at least one of said substances being used as a binder and being capable of converting its states of aggregation in the mixture of the type of crystal-liquid or crystal-gas under the action of intrinsic or reflected radiation obtainable from the object being recorded and at least one said substances which is used as a filler present in the heterogeneous mixture in the form of particles that are randomly arranged in the layer to assure its uniform optical density, said binder being in a solid state when free of exposure to radiation and holding said particles against migration and being capable of absorbing thermal radiation for converting into a liquid or gaseous substance, said particles being responsive to a force field and capable of absorbing radiation to melt that portion of the binder surrounding the particle which absorbs radiation for permitting the irradiated particles to migrate and to form chains that are extended along force field lines as a result of the interaction between the heated particles in a force field; introducing said layer of said heterogeneous mixture of substances into an electric or a magnetic force field at right angles to the layer surface; projecting onto said layer of said heterogeneous mixture of substances an image of an object being recorded with the help of the intrinsic or reflected radiation obtainable from the object being recorded to cause the heating of said particles on the illuminated sections of the layer, which heated particles then in turn melt the portion of the binder adjacent to the heated particles to permit the particles to migrate in response to the force field; said projecting step also causing the converting of the state of aggregation of the binder surrounding the heated particles to either crystal-liquid or crystal-gas, thus enabling said heated particles to orient their position in the binder to aggregate in chains perpendicularly to the surface as a result of the interaction with said magnetic or said electric field; and fixing the projected image by converting the state of aggregation of the binder by switching off the recorded object radiation to cause the binder to cool and re-crystallize.
