摘要： PURPOSE:To obtain a hologram recording medium with a sensitivity even to a semiconductor laser wavelength scope, and an excellent heat-proof and water proof property, by using a positive ion color-borate negative ion complex as a polymerization starting agent. CONSTITUTION:A hologram recording medium is formed by using a monomer to allow to polymerize, and a positive ion color-borate negative ion complex to allow to start polimerization, in a polymer. When the recording medium is exposed in a visual light, it shows sufficient sensitivity in the wavelength scope from the argon laser to the semiconductor laser according to the absorption of the polymerization starting agent. And by exposing an interference pattern by the interfering laser of two beams of an object beam and a reference beam with an adequate wavelength in this wavelength scope, the polymerization is promoted, and a reflection type or a permeation type of volume phase type hologram is formed. Consequently, a hologram with no color, a high transparency and heat-proof property, and a low water absorption coefficient can be obtained.

摘要： PURPOSE:To obtain images which have excellent stability after recording, change less with lapse of time and are particularly free from color fogging by incorporating a photosensitive metal salt, org. metal salt, reducing agent, and oxidizing agent into the same layer or different layers. CONSTITUTION:The photosensitive body having at least the photosensitive metal salt, the org. metal salt and the reducing agent is subjected to image exposing, by which latent images 4 are formed thereon. The latent images 4 are brought into reaction as a catalyst with the org. metal salt and the reducing agent by heating the photosensitive body to form dyes and metals 6. The metals 6 and the oxidizing agent 9 are brought into reaction by applying energy thereto. The images by the metals 6 are non-visualized in this way. The high- quality color images are easily obtd. in this way.

摘要： PURPOSE:To stably obtain many sheets of printed matter by combining a polysilane-contg. layer and a silver halide-contg. photosensitive layer and forming images on the polysilane-contg. layer even by digital exposing. CONSTITUTION:This printed matter has the photosensitive layer 1 contg. an org. silver salt and silver halide, a charge generating layer 3 and the polysilane- contg. layer 2. The printing plate having the photosensitive layer 1 contg. the org. silver salt, the silver halide and a reducing agent, the polysilane-contg. layer 2 and the charge generating layer 3 is subjected to image exposing and heating and is subjected to the 1st uniform exposing from the photosensitive layer 1 side. The polysilane-contg. layer 2 is then electrified. This polysilane- contg. layer 2 is subjected to the 2nd uniform exposing. Further, a developer is applied to the polysilane-contg. layer 2 and thereafter, the developer on the polysilane-contg. layer 2 is transferred to a body to be recorded. The image exposing even with long waves from visible light to IR rays is executed in this way and many sheets of the printed matter are easily obtd.

摘要： PURPOSE:To obtain a high resolution by laminating a first photosensitive composition varying from a hydrophilic property to a hydrophobic property and vice versa on an image forming substrate and a specified second photosensitive composition. CONSTITUTION:This material has a multilayered constitution in which the first photosensitive composition layer 4 incorporating the photosensitive material varying the wettability of the surface by exposing it from the hydrophilic property to the hydrophobic property and vice versa and the second photosensitive layer 2 incorporating a heat development type photosensitive composition are incorporated together. The first photosensitive composition varying from the hydrophilic property to the hydrophobic property and vice versa exposing an active light on the image forming substrate, and the second thermal development photosensitive composition in which a stripped film, a photosensitive silver halide, an organic silver salt and a reducer are incorporated, are laminated. Thus the edge section of the image is cut sharply and the resolution is improved.

摘要： PURPOSE:To perform automatic focusing in an arbitrary scanning position and to perform automatic focusing even at the time of turning-off the beam for a prescribed work by making the wavelength different between the light for the prescribed work like recording on an irradiated body and the light used for automatic focusing. CONSTITUTION:An irradiated body 5 is scanned with the luminous flux from a light source 1 to perform the prescribed work like image formation, and an automatic focusing mechanism is provided which uses the light from the irradiated body 5 to control the condensing state of the scanning luminous flux on the irradiated body 5, and a wavelength lambda1 of the scanning luminous flux for the prescribed work and a wavelength lambda2 of the scanning luminous flux for automatic focusing are made different from each other. That is, the irradiated body 5 is so constituted that the prescribed work is performed only with the light having the wavelength lambda1. Thus, automatic focusing is directly performed with the light having the other wavelength lambda2, which is not used for the prescribed work, in an arbitrary position of the effective scanning area on the irradiated body 5, and this function is surely realized with a high precision.

摘要： PURPOSE:To accomplish focusing at an arbitrary position in an effective scanning area by irradiating a photosensitive body provided with a higher harmonic wave generating layer with a light flux and performing recording and focusing operations by means of the light flux which is sent from a single light source and used for irradiating the effective scanning area of the photosensitive body. CONSTITUTION:The photosensitive body 3 irradiated with the light flux from the light source 1 through an optical system is provided with the higher harmonic wave generating layer and a photosensitive layer. Image recording is performed on the photosensitive layer by either a higher harmonic wave or a fundamental wave which are generated in the higher harmonic wave generating layer and automatic focusing operation for the light flux on the photosensitive body 3 is performed by the other wave. Therefore, image recording and automatic focusing are simultaneously performed by the light flux from the single light source 1. Hereby, focusing is performed at an arbitrary position in the effective scanning area of the photosensitive body 3.
