Abstract

PURPOSE:To obtain reversal paper having excellent tone reproducibility by specifying the relation between the average value of the point gammer in the exposing region corresponding to 0.80-1.30 coloring forming density and the average value of the point gammer in the exposing region corresponding to 1.30-1.80 coloring forming density. CONSTITUTION:The relations between r1 and r2 is (r1-r2)>=0.20 when the average value of the point gammer in the exposing region corresponding to 0.80-1.30 coloring forming density is designated as r1 and the average value of the point gammer in the exposing region corresponding to 1.30-1.80 color forming density is designated as r2 with the characteristic curves of all of photosensitive layers. The contrast in the high-density part is so high that the reproducibility is lowered and a 'defaced image' is formed if (r1-r2) is smaller than 0.20. The contrast in the high-density part is so low that a 'less sharp image' is formed if (r1-r2) is larger than 1.2. Both cases are undesirable. The reversal paper having the excellent tone reproducibility in the case of obtaining a positive print from a reversal film as an original is thereby obtd.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a silver halide color reversal reflective print photosensitive material, and in particular, the silver halide color reversal film exhibits excellent tone reproducibility when used as an original. The present invention relates to a silver halide color reverse reflection printed photosensitive material.

[Conventional technology]

In contrast to the so-called "negative-positive system," in which a negative image obtained by photographing with negative film is used as an original and a positive image is obtained by printing it on negative color photographic paper (hereinafter referred to as negative paper), silver halide color A positive image obtained by photographing with a reversal film (hereinafter referred to as reversal film) is used as a manuscript to create a silver halide color reverse reflection print photosensitive material (hereinafter referred to as reversal paper).
A positive image is obtained by printing on a so-called “
In the latter case, it is an excellent system that allows you to view the positive image of the universal film, and also print it on reversal paper to obtain a positive image depending on the purpose.

Among the above two systems, the reason why the "negative-positive system" has become dominant in recent years is that negative film has a larger shooting latitude than reversal film.
The development process of the "Negative-Positive System" is simpler than that of the "Positive-Positive System", but the bigger problem is that the gradation of the reversal paper is inappropriate, and the development process of the "Negative-Positive System" is simpler than that of the "Positive-Positive System". Compared to a print, high-density areas are not reproduced with high contrast, and low-density areas are, on the contrary, soft in tone and appear cloudy with poor clarity.

In contrast, Japanese Patent Laid-Open No. 61-50135 proposes that the gradation of reversal paper be linear. By making it a linear type, the tone reproduction range is expanded,
This proposal improves the depiction performance in high-density areas and improves the number of blanks in low-density areas, but since this proposal also provides suitability for printing from reflective originals, there is no problem with matching against reversal film, which is a transparent original. The print quality has not yet reached the level of print quality obtained with a negative-positive system.

[Problem that the invention seeks to solve]

Therefore, the object of the present invention is to provide a versatile paper with excellent tone reproducibility when obtaining a positive print using a versatile film as an original.
