摘要： PROBLEM TO BE SOLVED: To provide an image recording method, by which a frameless print can be obtained by neither staining apparatuses, recording paper or the like nor reducing the expected life span of the apparatuses, and an image recording sheet employed in the method. SOLUTION: This image recording sheet is produced by providing at least a recording layer 12 on one side of a support 10 and by laminating a releasing layer 16, a self-bonding layer 18 and a removing sheet 20 in the order named on the other side of the support 10. The image recording method for recording an image with the image recording sheet is, at first, to record an image beyond a notch 22 when the image is recorded at a portion surrounded by the notch 22 with an image recording under the state that the releasing frame-like notch 22 is present on the recording layer 12 side of the image recording sheet. Next, a separation is performed between the releasing layer 16 and the self-bonding layer 18 of the image recording sheet, resulting in obtaining a sheet, in which an image is formed over the whole surface of the separated recording layer.

摘要： PURPOSE:To improve the chromatic sectioning properties of a thermal recording material which develops a varying color by providing an intermediate layer having the decomposition wavelength of a diazonium salt compound which becomes longer in proportion to a distance between a layer in which said compound is contained located near a support and the support and allowing a lower decomposition wavelength light to transmit through an area between thermal coloring layers and an upper decomposition wavelength light to be absorbed. CONSTITUTION:The decomposition wavelength of diazonium salts contained in each thermal coloring layer becomes longer in proportion to a distance between a layer near a support and the support. The thermal recording material of each thermal coloring layer incorporates and intermediate layer which allows the decomposition wavelength of diazonium salt compounds contained in a lower layer to transmit and that of the diazonium salts contained in an upper layer to be absorbed. Subsequently, a light emitted for the decomposition of unreacted diazonium salts which are contained in an aimed thermal recording layer is absorbed by the intermediate layer located right below after thermally recording of the aimed thermal recording layer. On the other hand, the light almost does not act on the diazonium salts in the lower layer under the aimed layer. Subsequently, the diazonium salts contained in layers other than the aimed layer do no longer decompose, if thermal recording and optical decomposion processes are repeated.

摘要： PURPOSE:To obtain a radical capturing agent having satisfactory radical capturing ability, well permeating the walls of capsules and forming no harmful coloring matter by a reaction with a photo-radical generating agent by using a specified hydroquinone deriv. CONSTITUTION:When a recording layer contg. a radical capturing agent and microcapsules contg. a photooxidizing agent generating a radical and oxidizing the leuco body of a dye is formed on a substrate to obtain an image forming material, a hydroquinone deriv. represented by formula I (where each of R1 and R2 is a group contg. 1-18 carbon atoms and R1 and R2 may be different from each other) is used as the radical capturing agent. This radical capturing agent has such superior characteristics that it acts on a photo-radical generating agent, captures a generated radical, forms no harmful colored compd. at the time of capturing and can firmly be isolated by the walls of capsules at ordinary temp.

摘要： PURPOSE:To increase the printing efficiency with the forming of colors at high density with low energy by providing a thermosensitive recording layer, consisting of a blended inorganic compound containing crystallization water, which indicates a coloration due to heat. CONSTITUTION:An inorganic compound containing crystallization water at a crystallization water release temperature of 100 deg.C or less is blended with an electron-donative dye precursor and an electron-receptive compound, both capable of indicating a coloration due to heat, to prepare an application liquid for dispersion. This dispersant is applied to the surface of a support and dried to form a thermosensitive recording layer and thus a thermosensitive recording material is obtained. With the application of the thermosensitive recording material, especially the crystallization water of the inorganic compound containing a crystallization water is released, and consequently, the printing is performed efficiently to obtain a coloration at high density with low energy in the printing process. The typical examples of the above-mentioned inorganic compounds containing said crystallization water are (NH4)Cr(SO4)2.12H2O, NH4ClMgCl.6H2O, etc.
