Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a photosensitive or heat-sensitive composition that directly develops color upon irradiation with actinic radiation or heat. Prior Art Various materials have been proposed that develop color upon irradiation with actinic radiation. Typical examples include non-silver salt copying materials such as blueprints, free radical photographs, photochromic materials, and dual scutrum. There is. Among these, blueprints use inorganic iron salts as coloring agents, and these iron salts have the disadvantages of being toxic, having low sensitivity, and requiring washing with water for processing. There is. In free radical photography, pigments are formed based on free radicals generated when polyhalogen compounds such as _CBr4 are decomposed by ultraviolet rays, and can be processed dryly, and have advantages such as high sensitivity and high resolution. However, it has drawbacks such as poor preservation of raw samples due to volatilization of polyhalogen compounds, and extremely poor preservation of dye images obtained. Photochromic materials fix images using compounds that change into pigments when exposed to light of a specific wavelength, but if placed in a dark place or exposed to long wavelength light, they become colorless and the image cannot be fixed. I can't. Furthermore, the dual spectrum is, for example, 4-
An image is obtained by heat development using a combination of methoxy-α-naphthol and silver behenate, and in addition to requiring heat development, it has the drawback of poor image quality in terms of resolution and the like. As described above, conventional materials have poor storage stability, require development processing, and are difficult to handle, cannot fix images, and have poor quality images. Each has its own drawbacks. In addition, traditional materials

It is also possible to use a coating film provided on a support (for example, baryta paper, RC paper, polyethylene phthalate, triacetyl cellulose, aluminum plate, zinc plate, etc.). In this case, the surface of the support may be subjected to a known subbing treatment, if necessary. The composition of the present invention is photosensitive or heat sensitive to actinic radiation and/or heat and directly forms indoaniline, indophenol, indamine, azomethine and azo dyes. Such a dye is obtained by reacting a compound represented by the above general formula () with an active methylene or methine compound. In this case, the reaction is activated under alkaline conditions, so that the composition contains an organic or inorganic base [e.g. triethylamine, tributylamine, di(ethylhexyl)amine, di(cyclohexyl)amine, pyrrolidine, piperazine, caustic soda]. , caustic potash, soda carbonate, potash carbonate, ammonia, etc.). The composition of the present invention may contain a compound having an active methylene group or a methine group and a compound represented by the general formula (), and the molar ratio of the two is as follows:
From the perspective of the color development mechanism, equimolar amounts are sufficient, but approximately 10:
The ratio is preferably 1 to 1:10, and more preferably 2:1 to 1:2. Further, each compound may be used alone or a plurality of compounds may be used. As described above, the composition of the present invention basically consists of a compound having an active methylene group or an active methine group and a compound represented by the general formula (). In this case, it is more preferable in terms of sensitivity if the composition further contains a compound that generates free radicals and/or a compound that has oxidizing power when exposed to actinic radiation or heat. Get results. Although the detailed mechanism by which such a favorable result occurs is not clear, it is thought that this is probably because such a compound activates the above-mentioned dye-forming reaction and acts as a sensitizer. Such compounds may be used alone or in combination of a plurality of compounds. In addition, these compounds that generate free radicals or generate compounds with oxidizing power are usually
In many cases, actinic radiation has a greater sensitizing effect on photosensitivity than heat. The molar ratio of the compound of general formula () and these sensitizers is preferably from 1:10 ^-4 to 1:10, and more preferably from 1:10 ^-2 to 1:1. get. The composition of the present invention may be subjected to actinic radiation and heat, either alone or simultaneously. When both are applied at the same time, it can generally be said that sensitization is more likely to occur than when actinic radiation is applied alone or when heat is applied to each. Incidentally, by further containing a quinone compound or the like in the composition of the present invention, it is possible to stabilize the image. The active radiation for sensitizing the composition of the present invention is preferably ultraviolet to visible light having a wavelength in the range of 200 mm to 700 mm, more preferably light in the range of 340 mm to 500 mm. When the light is from ultraviolet to visible light, it may be monochromatic light or continuous light. Note that electron beams, X-rays, etc. may be used depending on the case. Various sources of active radiation can be used. For example, it may be a tungsten lamp, a high-pressure mercury lamp, a xenon lamp, a carbon arc lamp, a halogen lamp, a copying fluorescent lamp, a laser, or a commonly used electron beam or X-ray source. Further, as a heat source for coloring the composition of the present invention, a heat source capable of heating to about 80°C to 300°C is preferably used, and a temperature of 100°C to 150°C is preferably used. Various heat sources such as infrared lamps and resistance heaters are used. By applying such actinic radiation and/or heat to the composition of the present invention, various corresponding pigments are formed as described above without any development treatment. In the composition of the present invention, indoaniline, indophenol, indamine, azomethine, and azo dyes that are directly formed by actinic radiation or heat are dyes that are formed in silver halide color photographic light-sensitive materials. The fastness of these pigments to light, humidity, etc. is already well known. Such a composition can be used as it is as various photosensitive or heat-sensitive image recording media in the form of a solution or as a coated product. Alternatively, it can be used as a light or heat indicator. Furthermore, various other photosensitive materials can be contained in this composition to form and use various composite photosensitive materials such as PS plates. Specific Effects of the Invention The photosensitive or heat-sensitive composition of the present invention directly develops color under the action of actinic radiation or heat to form a dye, and therefore does not require any development treatment. Furthermore, the formed dye image is robust and has extremely high image storage stability. Furthermore, images of any hue can be obtained upon request. In addition, the image quality is also good.
