Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method of directly obtaining a color positive image from a color original, and more particularly to a method of reproducing color saturation and hue more faithfully to the original.

[Background of the invention]

The following methods have generally been used to obtain color positive images directly on color originals or highly luminescent materials. That is, a color original is irradiated with light from a halogen lamp or the like, and the reflected or transmitted light is imaged and exposed on the surface of a photosensitive material using a lens or the like, followed by development processing to obtain a positive image. Color originals include transmissive ones such as color slides and movie positive film, and reflective ones such as color prints, color prints, illustrations, and paintings. Photosensitive materials include those that directly obtain a positive image, such as color reversal film using a reversal processing method, and Color Du! Replicating film, color reversal paper, auto-positive color film, auto-poso color beno! -1 Diffusion transfer type instant film, diffusion transfer type dry color peno, etc. are used. In this method, the following two methods have been conventionally used to adjust the color balance of the obtained positive image. One is called the additive color method, in which light is divided into three colors: green and red.
This is a method of separating the primary colors and exposing them three times. Although this method requires three exposures, is complicated and has poor productivity, it has the advantage of providing a positive image with good color separation and excellent color reproducibility.

The other method is a subtractive color method, in which cut filters of yellow μm 1, magenta, and cyan are inserted at any position in the optical system, and the exposure amount is adjusted. This method has advantages such as requiring only one exposure, simple equipment and operation, and short printing time, but has disadvantages such as poor color separation and color reproducibility.

Therefore, it is desired to realize a color image forming method with excellent color separation and color reproducibility in a subtractive color exposure method.

To this end, it is conceivable to increase the separation accuracy for reading color density information from the original image by sharpening the spectral spectrum of the back, green, and red sensitivities of the photosensitive material.

In the past, attempts have been made to sharpen the spectral sensitivity spectrum by incorporating a suitable light-absorbing coating into a photosensitive material (Japanese Patent Publication No. 51-1419, JP-A No. 52-20830, or JP-A No. 57-1999). -112750 etc.). In addition, attempts have been made to sharpen the spectral sensitivity using external filters in negative/glint systems (tIff Patent Publication No. 53-64037, Japanese Patent Laid-Open No. 53-6403,
1 (No. 13627).

(Problem to be Solved by the Invention) However, in the method of incorporating a light-absorbing dye into a light-sensitive material, the amount of K that allows the dye to achieve the desired effect is limited to the absorbing dye (K).
This has the disadvantage that the wavelength is broad, and it absorbs light in the originally sensitive range, lowering the sensitivity. Further, the method using an external filter is intended for use in a negative print system), and there is no teaching of a so-called positive-positive system in which a color digital image is directly obtained from a color original. Color reproduction in positive/positive systems is said to be more difficult than in negative/positive systems. negative·
In the case of a positive system, all the materials used are negative films, and the image is mostly formed from azomethine dye (coupled product of coupler and developing agent).

Therefore, the permissible range of spectral sensitivity on the printing sensitive material side is relatively large. However, in the case of a positive-positive type, the original image is a transparency, an outer color slide film, or an inner color slide film, each of which has a significantly different coloring pigment. Furthermore, if the original painting is a reflective positive painting, the original painting can be used for a wide variety of purposes, including color photographic prints, printed matter, paintings, illustrations, real objects, etc. Therefore, there are a wide variety of coloring materials that form images, such as azomethine dyes, azo dyes, organic pigments, and inorganic pigments.
, magenta, and cyan cannot be specified. Faithfully reproducing each of the original images using these various coloring materials is an extremely difficult task for direct positive type color photosensitive materials.

Accordingly, an object of the present invention is to provide a method for forming positive-positive color photographic images with excellent color reproducibility even when using the subtractive color method which is excellent in productivity of the first K printing operation.

The second object is to provide a method for directly obtaining positive color images with faithful color reproduction from various color originals with different color materials.

(Means for Solving the Problems) As a result of intensive studies, the present inventors have found that the above problems can be achieved by the following method.

(However, if there are two or more maximum sensitivities, refer to the wavelength on the shorter wavelength side) or the wavelength that is longer than the long wavelength end of the spectral sensitivity distribution of the green sensitive layer and the spectral spectrum of the red sensitive layer. The peak of the sensitivity distribution (refers to the highest sensitivity wavelength; however, if there are two or more highest sensitivities, refers to the shorter wavelength), and the optical density of the peak is 0.8 or more, and The 3/4 width (wa/4) of the absorption peak is 5 mm or more, and 1

The sensitivities in Table 2 indicate the relative sensitivities of the red, green, and blue sensitive layers when exposed using filters 101 to 129. The color reproduction values indicate Munsell's floma values for red, green, and back colors.

When the spectral sensitivity spectrum of the light-sensitive material of Example 1 was measured, the long wave edges of the blue-sensitive layer and the green-sensitive layer were 500 nm, respectively.
It was 560 nm.

Furthermore, the peak wavelength of the green sensitive layer and red sensitive layer is 548 nm.

At 650 nm.

From Table 2, it can be seen that the samples according to the present invention can realize an improvement in color saturation on prints, and also have less decrease in sensitivity.
