摘要:
A method for producing an image comprising image-wise exposing a light-sensitive layer containing a sensitizing agent and an image forming compound which can be transferred at non-exposed areas to an image receiving layer upon heating at about 80.degree. to about 200.degree. C, and which can be changed to a non-transferable compound at exposed areas, contacting the light-sensitive layer with the image receiving layer containing a compound which forms a colored image upon reaction with the image forming compound, and heating the light-sensitive layer to transfer the image forming compound to the image receiving layer at non-exposed areas, wherein the image receiving layer comprises an organic tellurium compound and a binder formed on a support.
摘要:

摘要:
A method for producing a phase hologram by bleaching a silver image of an amplitude hologram formed on a light-sensitive silver halide photographic material, wherein the bleaching is conducted using a solution containing an N-halogeno compound to inhibit the binder of the layer having the silver image therein from swelling.
摘要:
A bobbin transfer system of a spinning frame (1), in which a series of trays (13) are carried on a pair of carrier rails (14, 15) driven to repeat a back-and-forth reciprocation. Hooking members (23) are arranged along the carrier rails (14, 15), which allow the trays (13) to pass thereover during the forward displacement of the carrier rail (14, 15) but inhibit the backward displacement of the trays (13) by the action of hooks (23a) formed on the hooking member (23) at a distance from each other corresponding to N times the spindle pitch wherein N satisfies the equation .DELTA.A.gtoreq..DELTA.D.times.N (wherein .DELTA.D stands for a manufacturing tolerance of a diameter of the tray 13 and .DELTA.A stands for an allowance for a grip distance of a bobbin catcher in an auto-doffer) and p stands for a spindle pitch. Accordingly, the trays (13) are transferred intermittently as the carrier rails (14, 15) reciprocate at a stroke larger than the spindle pitch.
摘要:
An infrared absorbent comprising .alpha.-diimine metal complex is disclosed. With the use of the infrared absorbent, there is provided an infrared absorbing material capable of absorbing a near-infrared light having a wavelength of 700-1500 nm and a far-infrared light. The infrared absorbent has a good fastness to heat and light. The infrared absorbing material is suitable for an optical filter and optical information recording medium.
