Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for creating a colored slide that can instantly create a blue sushi film from a subject by converting images of diagrams, books, etc. into slide films.

Currently, slide projection is often used in public places such as lectures and academic conferences as a means of transmitting visual information to a large number of people at once.

In particular, the so-called ``Blue Pack Lid'' can give a blue negative projection image even in slide film.
Slide film is preferred because it provides clear images. The reason for this is that slide photography is usually done by projecting an image onto a screen in a dark room, but this screen image is a positive chalk image and has a blue color to 41 compared to the projected image. This is because the image projected as a negative image looks more vivid and is also preferable in terms of reducing Saka's fatigue.

However, although blue negative slide film is a preferable means of transmitting information that provides clear projected images, there is no easy way to create slide film, and it is difficult to create slide photographs manually on the spot, such as using a copier. In order to obtain it, its use had to be limited to specific areas such as public announcements. For example, to create a blue negative violet slide using the traditional slide creation method, first photograph the subject using Shuku-style chain salt film, then
This is an extremely complicated and time-consuming process in which a black negative film is created by developing with a developing gI solution, further fixed, washed with water and dried, and then a blue negative slide film is created using diazo film through the black negative film. is necessary. Moreover, the K used to create slides in 11th is empirically determined to be the optimal black color, depending on the size of the letters and diagrams of each subject, the thickness of the spear, the reflection density of the background, and the reflection density and color tone of the 11th stroke. After controlling the photographing conditions to obtain a negative image, we also had to select the printing conditions and production conditions to obtain the optimal blue negative slide film (such as... Skill is required. Therefore, it is necessary for unskilled people to prepare for a certain amount of trial and error, and in some cases be prepared to waste a considerable amount of time and repeat the process, such as having to start over from the beginning to photograph the subject. On the other hand, even if you hire a professional, careful preparation, a considerable amount of time, and expense are required, which has been a major obstacle to the use of slide photographs.

On the other hand, Akiko Motoya and his team worked hard to find a simple method for creating slides in order to solve the above problems. By adopting a completely new method for creating slides as shown below, they were able to create blue slides extremely easily and immediately. He discovered that it was possible to create a jIM slide film and completed the invention.

That is, the present invention involves the steps of photographing an object on a heat-developer dry-processed steel salt film with a camera, and then heating and imaging it to obtain a black negative film of the same size as the slide film. The film and the diazo film are brought into close contact with each other, and then the film is passed through the black neo film. 1. This relates to a method of creating a slide file.

The greatest feature of the present invention is its rapidity. That is, as mentioned above, the conventional method using warm-temperature copper salt film required complicated and sophisticated work, and it was necessary to prepare for a considerable number of days in advance to prepare the slide film. On the other hand, according to the method of the present application, J
Slide films can be created extremely quickly.

Also, when dealing with public presentations that have a set date, it is true that slides need to be corrected or added just before the presentation! As is often the case, it is not possible to meet the deadline by using the conventional outline film. However, according to the method of the present application, it is possible to make necessary corrections to the manuscript,
After creating the necessary manuscript, the person concerned can easily convert it into slides immediately, allowing them to make corrections and additions to the slides right before the presentation.

As described above, according to the present invention, all the problems that made the use of slide photographs mentioned above were solved, and also
Utilizing the advantage of being able to slide instantly, which was not possible when using rice wet copper ingots, it has become possible to use it in new ways, including last-minute additions and corrections. This is extremely convenient for those involved in actually creating the slides, and is the greatest feature of the present invention.

Another feature of the sergeant of the present invention is to transfer an image of a heat-developed*m dry silver salt film created on a tube to a diazo film, so that it can be heat-developed! The 1IIIL type chain salt film transfers the ** possessed by Lum to the diazo film, and at the same time successfully overcomes the disadvantages of the heat-developable dry bale salt film using the advantages of the diazo film itself.

In other words, to explain more specifically, the feature of heat-developable dry copper salt film is that it has high sensitivity to the extent that the subject can be directly imaged by the camera, but the drawback is that the image after heat development is There is a problem with the stability of the
The background part (unexposed part) of ii* may become warm. Therefore, when directly photographed S* image dry silver halide film is placed in the slide projection 411 and projected, a thermal fog will occur on the TI image due to the strong radiation and heat from the light source of the projector.
When projecting a slide, you may end up seeing K<<.

On the other hand, although diazo film has low sensitivity,
**The stability of the processed images is excellent.

6- Here, according to the method of the present invention, the characteristics of the heat-developable dry silver salt film, which has extremely high sensitivity, are utilized, and the characteristics of the diazo film, which has excellent thermal stability of images, are utilized, and at the same time, both films are It is possible to provide a completely new film production method that eliminates each of the drawbacks of the above. In addition, by the method of the present invention, for the first time, with extremely simple operation,
It is considered that a dramatic effect was obtained, which is equivalent to the achievement of a diazo film that has substantially the speed of camera photography.

Furthermore, one of the features of the present invention is that it can be used as a total system.
The point is that slide films can be created without actually going through a lot of wet processing steps. In other words, the process of creating the first black negative image is a completely dry process called heat development, and the diazo processing process also uses chemicals such as ammonia if the diazo film is selected, but it simply passes through a gas atmosphere. It can be developed with some processing. Therefore, immature**
However, it is possible to easily create slide films in a single office without getting your hands dirty.

1- Another advantage of the present invention is that a clear blue negative chick slide film can be obtained by the simple operation described above. This blue negative slide film is the most preferred color slide film because it is easy to see and does not cause eye strain.

Another feature of the present invention is that the developed black negative film can be seen clearly. Due to this, even a novice can immediately determine whether the black negative film is successful or not, and can immediately change the shooting conditions and ask whether it is necessary to create the black negative film again or transfer it to the next diazo film. The advantage is that it is possible to determine whether or not it is possible to proceed to the next step, and blue negative film can be produced extremely quickly.

Furthermore, one of the advantages of the present invention is the process of creating a blue negative film through a black negative film, which further improves sharpness, creating a blue negative type slide film with extremely high contrast and clarity. It is possible. This is because the gamma value of the photographic diazo film is usually about 1 to 1.8, so the contrast is higher than that of the black negative film of the master film. For example, a heat-developable dry copper salt film usually has a higher optical conversion of the non-g element than a wet silver salt film, and
Controlling the gamma value is also difficult, but when transferred to diazo film, the sharpness improves in the 5th step, which dramatically increases the handling tolerance of heat-developable dry silver salt film. The total system can be made extremely easy to handle.

As described above, the method of the present invention has extremely superior features beyond simply replacing a black film with a blue film, and can provide the extremely excellent multiple synergistic effects as described above. The problem is that the K11i image could not be easily obtained.

Now, in the present invention, first, a desired subject is photographed with a camera on a heat-developable dry type silver halide film, and then heated and photographed with a slide film. The desired subject may be anything that is photographed with a camera through an optical lens system, but the most commonly used form is letters, numbers, and diagrams drawn in a flat manner on a sheet. It is often similar. The size of this subject may be any size, and the color tone to be drawn is often not limited. Most preferably, however, clear letters, numbers, and
This is preferable for achieving the desired clear finish on the slide film.

The above-mentioned subjects are photographed with a camera using a heat-developable dry-chain salt film. The essential ingredients include at least four components: a photosensitive halogenated steel, or a photosensitive substance formed from an organic salt additive and a dye, a quantity agent for silver ions, and a binder. It is a film made by adding additives of each woodcutter, and is typically made by Tetsuko @ 43-. No. 4924, Tetsu Gongsho 5

These are photosensitive materials as described in various publications. This thermal m*ii dry silver halide film can be used as a normal photosensitive film, which is sensitive from the beginning, but it is also non-photosensitive under normal indoor light, so it must be preheated before use. It can even be a type of photosensitive film that only becomes photosensitized by doing so.

Incidentally, the thermal IA imaged dry silver salt film is exposed to strong light in order to sensitize the diazo film in the next step. Under this light control, it is essential that there is no noticeable heat build-up, but the transparent parts of the heat-developed dry silver halide film mentioned above turn black under this level of strong light. However, the bright areas may become slightly colored.If such a phenomenon occurs, it is difficult to sensitize the intended diazo film. , it becomes necessary to apply a larger amount of light to the black negative film.

Therefore, a suitable heat-processable dry silver salt film for producing 1% KJI color negative film is one containing an organic) logon compound in order to remove the fine silver particles generated under strong light. suitable for things. As this organic halogen compound, 1,2.3.4-nato-2bromobutane,
So-called original oxidizing agents such as tetrabromoxylylene, 1,2-short ethane, tribromoethanol and derivatives thereof are suitable.

(Margins below) The heat-developed dry film as described above may be photographed using a single still camera and then heat-developed.
You can also take pictures using a special camera with a built-in heat developing device.
Photographs are often taken from a fixed position while controlling the brightness above the subject. In addition, since it is inconvenient to control the brightness of the subject, reduction ratio, exposure time, aperture, etc. each time, the subject and light source are fixed to some extent in advance, and the camera position is adjusted according to the reduction ratio. It is preferable to use a dedicated flat-bed camera that can be moved up and down.

The heat-developable dry silver salt film photographed as described above is usually developed by heating at 80 to 150 C and 0.1 to 60 iIp@degrees. Until the end of this step, the film must not be exposed and is subjected to a heat treatment step in a dark room or, more preferably, to thermal development in the same dedicated camera.

Note that the thermal bridge image method can be arbitrarily selected from general heating methods such as hot air, hammer heating, hot roll heating, and infrared layer heating.

In this way, the photographed, developed, and 11 black NetI film can be handled under a normal FM light inside a car, and its finish can be checked with the naked eye or with an optical index needle. . In other words, the transparent parts of the text and diagrams have an optical degree of about 0.05 to 0.2, the background parts with high optical negativity have an IsQ degree of 06 to IsQ, and the fine lines of the characters and diagrams, etc. It is desirable that the image be reproduced sufficiently clearly, and this condition is checked.

The black negative film produced in the first step as described above is converted into a blue slide film through the steps detailed below.

That is, first, the above-mentioned black negative film is brought into close contact with the diazo film by vacuum or mechanical pressure.
The diazo film is sensitized by passing the full mmjt through the black film with scissors.

At this time, the entire surface of the armpit black film is exposed to strong light in order to sensitize the diazo film.

By the way, scissors black negative film is slide throw 14
- If exposed to strong light such as a shadow, fogging will gradually occur due to heat; it is essentially a film that is susceptible to strong light and heat.

However, in the present invention, the heat 31tg IA type dry planer salt film is used in the process of photosensitizing the diazo film.
It may be surprising that it can withstand strong light and plays an important role as a mediator in the process of making blue slide films. The strong light source for sensitizing the diazo film may be any light source that emits light with a wavelength that can sensitize the diazo film, such as various mercury lamps, halogen lamps, xenon lamps, etc. lamp, metahalide lamp.

Examples include arc lamps and black lamps.

Since the diazo film is sensitized in close contact with the black film, it is preferable to use parallel light as the light source, but there is no need to pay close attention to the butt.

In addition, when sensitizing diazo film,! It is desirable that the heat generated from the I1 layer not heat the black film, and the transparent base of the glass and base that catalyzes the black film is
Preferably, the temperature is about 60°C or less.

Further, it is desirable that the diazo film and the black negative film are brought into close contact with each other. For example, a vacuum contact method or a pressurized contact method is preferable. -Furthermore, the diazo film and black negative film are brought into close contact and exposed to light.
IIK, jt, a presser is provided from the back side of the source, and it is desirable that this presser be black in order to prevent so-called halation, which reduces the sharpness of the diazo film, as much as possible.

Now, the diazo film used in the present eAK utilizes the photosensitivity of the diazo compound, and in places exposed to light, this compound decomposes, and in places not exposed to light, this compound reacts with the coupler in the alkaline state and becomes a dye. Any composition and method may be used as long as the photosensitive film is of a type in which it is formed in step 1.

Therefore, in the present invention, the photosensitive diazo film is subjected to various treatments depending on the characteristics of each diazo film and used as a slide film.

For example, so-called wet type diazo film, which is color-developed with an alkaline aqueous solution, is treated by passing the film through such an alkaline solution, and a type of diazo film, which is color-developed with ammonia gas, etc. Color develops in an alkaline gas atmosphere. In addition, the diazo film used in hot water contains compounds that release basic substances when heated.
Only heat treatment is applied.

The diazo film used in the present invention gives a blue image by MS processing, and includes so-called blue-black diazo films that give not only blue images but also blue-black images.

Furthermore, the present invention provides the above-mentioned blue or blue-black 811111 slide film as the most readable and pleasing slide film, but in some cases, ink-colored diazo film or sepia slide film may be used to give a slightly different appearance. Although it looks ugly, it can also give a different impression than the blue-toned slide.

A slide film made from the diazo film obtained as described above can be widely used as an ordinary slide film in exactly the same manner as conventional slide films.

Next, an example of the method of the present invention will be specifically described by way of an example.

(Margins below) H1- Example 1 A heat-developable dry copper salt film prepared in exactly the same manner as film a) of Example 2 of JP-A No. 1854-21326 was heated at 100° C. with a Seki heat hammer of approximately 3 iP. After preheating, it was cut into a rectangular size of 35 x 50 x and loaded into a still camera. The still camera I used was a Nippon Kogaku Nikon F with a 35mm F2 lens.
It is M. The manuscript was prepared with figures and tables written in black ink on B-4 size Kent paper. Place this manuscript on the table and use Toshiba photo reflector lamp, Flood 500W4.
I used a lamp to illuminate the surface of Otori S so that it was evenly bright.

This original was captured using the above still camera equipped with a tripod at f2.8.
．． ! Photographed in H seconds. The film obtained in this way is
The mixture was heated for 4 iP at 125° C. with a thermo roll in a +IUA. The obtained film was a clear black negative film with a maximum optical density of 0.9 and a maximum optical density of 0.09.

Next, this black negative film was combined with Fuji diazo film at one time, and immediately released as Nmar 5PD-10.
3, a black negative film was loaded facing downward, and irradiated with a special high-pressure mercury lamp for about 15 seconds. After the irradiation is completed, when the diazo film is fed into the machine of 8PD-103, a clear blue slide film developed with ammonia gas is obtained from 1 part of 5PD-103 for about 30 IP. Ta.

The slide film thus obtained was placed in a commercially available plastic slide protector and loaded into an ordinary projector, and a clear blue image was projected.

This series of operations was completed within 10 minutes, and it was found that a blue slide film could be produced extremely easily.

Example 2 Using a dedicated flat-bed camera equipped with a heating device, 10
The original sheets were photographed continuously and thermally developed.

This black negative film was coated with 8PD-1 in the same manner as in Example 1.
The image was transferred to a blue diazo film in step 03, and 10 sheets of slide film were prepared. The time required for this was 15 minutes, and the time for the next bale for each bale was 1 minute and 30 seconds.

The heat-developable dry silver salt film and the diazo film used in this example are the same as those used in Example 76111.
