JPH10171067A - Silver halide photographic sensitive material having fragrance - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a silver halide photographic sensitive material capable of emitting fragrance by rubbing the photosensitive material after development processing without effluence of the fragrance into developing and processing solutions, by incorporating the microencapsulated fragrance into a protective film layer above a silver halide emulsion layer from a support and/or a backing protective film layer. SOLUTION: The silver halide photographic sensitive material is provided on the support with at least one silver halide emulsion layer and at lest one nonphotosensitive hydrophilic colloidal layer, and the protective film layer upper than the emulsion layer form the support and/or the backing protective film layer contains the microencapsulated fragrance. The fragrance can be emitted only by rubbing when needed. The fragrance is added and contained in the protective film layer and/or the backing protective film layer by directly adding it into a coating liquid for forming the layer in an amount of 0.1-10g/m<2> of the photosensitive material.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a silver halide photographic light-sensitive material having an aromatic property, and more particularly to a silver halide photographic light-sensitive material which emits an aroma by rubbing.

[0002]

2. Description of the Related Art It is already known to impart fragrance to a print obtained by developing a silver halide photographic light-sensitive material. For example, Japanese Patent Application Laid-Open No. 63-121847 discloses that by adding a water-soluble fragrance and an emulsified fragrance to a final processing solution, a malodor caused by a chemical used in the processing step is reduced, and a fragrance is given to the photosensitive material after processing. It is described.
Also, Japanese Patent Application Laid-Open No. 8-82889 discloses that fragrance is imparted to printed photographic paper by various methods. However, in these methods, the fragrance is volatilized naturally, so that it is not possible to impart aromaticity for a long period of time. Also, it is not possible to emit a scent only when a scent is desired. Accordingly, an object of the present invention is to provide a silver halide photographic light-sensitive material capable of emitting a scent only when a scent is desired.

[0003] An object of the present invention is to provide a silver halide photographic material having at least one silver halide emulsion layer and at least one non-photosensitive hydrophilic colloid layer on a support. This can be achieved by a silver halide photographic material containing a fragrance microencapsulated in a protective layer and / or a back protective layer above the silver halide emulsion layer. When the silver halide photographic light-sensitive material of the present invention is desired to have a scent, the scent can be emitted by rubbing. That is, by describing whether the fragrance is contained in the protective layer or the back protective layer above the silver halide emulsion layer as viewed from the support, it can be used for discrimination between front and back. Also, even if development processing is performed, the fragrance does not flow out into the processing solution,
By rubbing the exposed and developed print, a scent can be imparted.

[0004] As the fragrance used in the present invention, known fragrances can be used. For example, perfume chemistry (Kyoritsu Zensho, published in 1961), those described in Class 24 perfume of 12996 chemical products (Chemical Daily, 1996) can be used. For example, amylcinnamic aldehyde, isocampyl cyclohexanol, ethylene dodecandioate, ethylene brasilate, 10-oxahexadecanolide, galaxolide, dihydroterpinyl acetate, benzyl acetate, isoamyl salicylate, cyclamenaldehyde, cis-jasmon , Citral, citronellal, dihydrojasmone, dimethylbenzylcarbinol, tetrahydrolinalool,
Methylyonone, linalool and the like can be mentioned.
In order to microencapsulate the fragrance, it can be microencapsulated by a commonly known microencapsulation method. For example, the new version microcapsules can be manufactured by the methods described in the manufacturing method, properties, and applications (published by Sankyo Publishing Co., Ltd., 1989) and JP-A-63-97223. In addition, commercially available products can be obtained by purchasing.

Examples of the photographic light-sensitive material which can be used in the present invention include color photographic paper, color print film (for display), black-and-white photographic paper, and Japanese Patent Application Laid-Open No. 6-5 / 1985.
No. 05580, black and white photographic paper with a dye image,
Examples thereof include a black-and-white film for printing. In order to add or contain the microencapsulated fragrance in the protective layer and / or the back protective layer, it may be added directly to the coating solution for forming the layer. The amount of addition is in the range of 0.1 g to 10 g per 1 m ² of the photographic light-sensitive material, especially 0.1 g.
A preferable effect is obtained in the range of 2 g to 5.0 g.

The binder or protective colloid which can be used in the protective layer containing the microencapsulated fragrance and the back protective layer of the present invention is mainly gelatin (alkali-treated gelatin, acid-treated gelatin or a combination thereof). Other than these, for example, gelatin derivatives, albumin, proteins such as casein, cellulose derivatives such as ethyl cellulose and carboxymethyl cellulose, sugar derivatives such as starch derivatives, polyvinyl alcohol, polyacrylic acid, polyacrylamide, and polymethacrylic acid Or a hydrophilic polymer such as a copolymer.

The protective layer containing the microencapsulated fragrance and the back protective layer of the present invention may contain an inorganic or organic hardener. As the hardener, for example,
Formaldehyde, chromium salts (chrome alum, etc.),
N-methylol compounds, dioxane derivatives, active vinyl compounds (eg, 1,2,5-triacryloyl-hexahydro-s-triazine, 1,3-vinylsulfonyl-2-propanol, etc.), active halogen compounds (eg, 4-dichloro-6-hydroxy-s-triazine, etc.), and mucohalic acids (e.g., mucochloric acid, mucophenoxycyclolic acid, etc.). These hardeners can be used alone or in combination. .

The protective layer containing the microencapsulated fragrance and the back protective layer according to the present invention include a coating aid, an antistatic agent, an improvement in slipperiness, an emulsification / dispersion, an adhesion prevention and an improvement in photographic properties (for example, development acceleration, A surfactant can be contained for various purposes such as high contrast and sensitization. Examples of the surfactant include saponin, alkylene oxide derivatives (polyethylene glycol, polyethylene glycol alkyl ethers, etc.), glycidol derivatives (alkenyl succinic acid polyglyceride, alkylphenol polyglyceride, etc.), fatty acid esters of polyhydric alcohols,

The produced sample was subjected to the development processing of Example 1. Unless rubbed, the developed sample did not smell the added fragrance. However, the scent was firmly felt by rubbing the image surface.

[0012] Example 3 In sample 5 of Example 1 of Japanese Patent Application No. Hei 8-192965, microencapsulated perfume so that 1 m ² per 1.5g in the top protective layer (Takasago Co., A sample was prepared in the same manner except that a lemon slurry) was added. The produced sample was subjected to the development processing of Example 1. The sample of black and white photographic paper with the developed dye image is
Unless rubbed, almost no fragrance was added. However, the scent was firmly felt by rubbing the image surface.

According to the silver halide photographic light-sensitive material of the present invention, when a fragrance is desired, the fragrance can be generated by rubbing. That is, by describing whether the fragrance is contained in the protective layer or the back protective layer above the silver halide emulsion layer as viewed from the support, it can be used for discrimination between front and back. In addition, even if the development processing is performed, the fragrance does not flow into the processing liquid, so that the fragrance can be imparted by rubbing the exposed and developed print.
