[57] ABSTRACT Acetylene sulfonyl compounds of the formula R--C CflCHzl PSQeiRLYXLEIQQ ELK. lld are 16- fined in claims are found to be useful as hardeners for the gelatin films of light-sensitive silver halide photographic materials. Synthesis and use of these compounds also are disclosed.
6 Claims, No Drawings SILVER HALIDE PHOTOGRAPH-NC ELEMENT CONTAlNlNG AN ACETYLENE SULFONYL COMPOUND AS HARDENER This invention relates to a hardener for the gelatin films of a light-sensitive silver halide photographic material, said hardener comprising a compound of the general formula,
R-C E C-(CH ),,SO R' wherein R is a lower alkyl group or a phenyl or alkylphenyl group; R is a hydrogen atom, a lower alkyl group or a phenyl, alkylphenyl, alkoxyphenyl or halophenyl group; and n is zero or 1.
Generally, a light-sensitive silver halide photographic material is prepared by forming various layers such as silver halide photographic emulsion layer, filter layer, inter layer, protective layer, sub layer, backing layer, etc. on a suitable support such as glass, paper or synthetic resin film. These layers are composed mainly of gelatin, so that the physical properties of said layers are dependent chiefly upon the physical properties of gelatin. However, gelatin itself is low in melting point, water-swelling and low in mechanical strength, and these properties are not desirable, or rather to say, are fatal drawbacks for the layers constituting a light-sensitive silver halide photographic material.
In view of the above, many attempts have heretofore been made to improve the physical properties of gelatin by treatment with various hardeners. These hardeners, however, have such photographic defects as being strong in desensitizing action and high in fog-forming action and, in the case of color photographic emulsions, bring about such drawbacks that they disturb the color developability of couplers or are too vigorous in hardening action to make the production of lightsensitive photographic materials difficult. Further, due particularly to the recent tendency of quick development and the adoption of automatic developing machines, the physical properties of films have come to be required more strong.
We made extensive studies on hardeners capable of giving gelatin films having such strong physical properties as to be suitable for the above-mentioned quick and automatic treatment of light-sensitive photographic materials to find that acetylene sulfones having the aforesaid general formula display excellent hardening actions without deteriorating the properties of photographic materials.
Examples of the compounds having the aforesaid general formula are as follows:

Phenyl 3-phenyl-2-propynyl sulfone The above-mentioned compounds may be synthesized by oxidizing corresponding acetylene sulfides according to, for example, the method disclosed in Bull. Soc. Chim. Fr., 1966, 3024. Procedures for synthesis of the compounds are set forth below as reference examples.

The reaction mixture is diluted with 1.0 l. of ether, and the dilution is washed with a saturated aqueous sodium bicarbonate solution and water in this order and then dried with anhydrous sodium sulfate. Subsequently, the solvent is removed by distillation, and the residue is subjected to distillation under highly reduced pressure to obtain 5.11 g of ethyl l-pentynyl sulfone, yield 54.3%, b.p. 96-97C./- l0' mml-Ig.

As is clear from the above table, the samples according to the present invention had no desensitizing action, successfully inhibited the fog and displayed excellent hardening effects.
EXAMPLE 2 The same photographic emulsion as in Example 1 was subjected to second ripening and then charged with a color coupler l-(4.'-phenoxy-3-sulfophenyl)-3- heptadecyl-S-pyrazolone. Thereafter, the emulsion was divided into 4 portions, and one portion was coated as it was on a support to prepare a control sample, while the remaining 3 portions were individually incorporated with each of aqueous solutions of the previously exemplified compounds (3), (6) and (11) and then coated on supports to prepare samples of the present invention.
These samples were individually measured to determine hardening effect in the same manner as in Example 1. Further, the samples were subjected to sensitometry by developing the samples with a color developer containing diethyl-p-phenylenediamine and effecting ordinary bleaching, fixing and water-washing treatments. The results obtained were as set forth in Table 2, in which the speed is represented by a relative speed.
EXAMPLE 3 A high speed light-sensitive silver iodobromide emulsion for roentgenography, which contained 3 mol of silver iodide was subjected to ordinary chemical ripening, and then charged with 100 ml. per liter of the emulsion of 5-methyl-7-hydroxy-s-triazolo(2.5- a)pyrimidine as a stabilizer and 2 g per liter of the emulsion of saponin as a coating aid. Subsequently, the emulsion was divided into seven portions, and one portion was coated as it was on a cellulose triacetate support to prepare a control sample, while the remaining six portions were individually coated to prepare samples of the present invention.
These samples were exposed according to the method regulated in Japanese Industrial Standards, subjected to high temperature quick development at C. for 1 minute and 30 seconds, at C. for seconds, and at 40C. for 25 seconds by use of a strongly alkaline roentgen film-developing solution containing l-phenyl-3-pyrazolidone and hydroquinone, and then measured in speed and fog. Further,.the sample were measured in hardening effects according to the same procedures as in Example 1.
