Description: FIELD OF THE INVENTION The present invention relates to a silver halide color photographic light sensitive material and particularly to a silver halide color photographic light sensitive material, which can provide an excellent dye-forming efficiency, a dye image with excellent light fastness, and improved color reproduction after extended storage. BACKGROUND OF THE INVENTION In the field of silver halide color photographic light sensitive material, which is hereinafter referred to as "color light sensitive material" or simply as "light sensitive material", it is necessary to obtain a dye image with sufficient maximum density (excellent dye-forming efficiency) produced by effective reaction of a coupler with an oxidation product of a color developing agent. Further, it is desired that the obtained dye image does not easily fade away or discolors even when it is exposed to light for a long time or when it is stored under conditions of high temperature and high humidity. However, recent demand for rapid processing has brought about disadvantages in reaction of a coupler with an oxidation product of a color developing agent. In order to improve the coupler reaction, it is well known that more hydrophilic high boiling point organic solvent is used. However, it has been found that, when a coupler-containing silver halide emulsion layer closest to the support of light sensitive material, which is most difficult to color develop, color mixture is produced after storage, resulting in marked lowering of color reproduction. Japanese Patent O.P.I. Publication Nos. 52-152722/1977 and 53-13414/1978 disclose a silver halide emulsion layer closest to the support of light sensitive material, the layer containing a saturated higher alcohol, whereby color developability in silver halide emulsion layers closer to the support as well as in the layer closest to the support is improved. However, it has also been found that this technique has the disadvantages in that color mixture improvement is insufficient and light fastness of the obtained dye image is deteriorated. JP 52-46816 discloses addition of a high boiling organic compound to a silver halide photographic light sensitive material. The organic compound has the following formula: wherein R 1 and R 2 are each H, optionally substituted alkyl, cycloalkyl, aryl or optionally substituted alkoxy and n is from 1 to 3. Magenta couplers of formula M-I as disclosed herein are not included in JP 52-46816. EP-A-0136924 provides silver halide light sensitive colour photographic material whether the silver halide emulsion layer comprises a polymer coupler and a compound of formula (I) Ar-O-(RO) p -H wherein Ar is an aryl, R is an alkylene group and p is an integer from 1 to 3. Magenta couplers of formula M-I as disclosed herein are not included in EP-A-0136924. BRIEF EXPLANATION OF THE DRAWINGS Fig. 1 shows infrared absorption spectra of 10 mM, 20 mM and 40 mM alcoholic compound A-4 (described later) solutions. The axis of the ordinates shows absorption (%), and the axis of the abscissas shows wave number (cm -1 ). Fig. 2 shows a figure in which the absorption ratios of the hydroxy group which forms an intramolecular hydrogen bond to the total content of the hydroxy group in alcoholic compounds are plotted against concentrations of the alcoholic compounds in dry CCl 4 solutions. The axis of the ordinates shows (hydroxy group which forms an intramolecular hydrogen bond/hydroxy group which forms an intramolecular hydrogen bond + free hydroxy group), and the axis of the abscissas shows concentration. SUMMARY OF THE INVENTION Accordingly, an object of the' invention is to provide a silver halide color photographic light sensitive material which can provide an excellent dye-forming efficiency of couplers, a dye image with excellent light fastness, and improved color reproduction after extended storage. DETAILED DESCRIPTION OF THE INVENTION The above object of the invention could be attained by the following silver halide colour photographic material: (1) a silver halide colour photographic material comprising a support and provided thereon a silver halide emulsion layer, wherein the silver halide emulsion layer comprises in admixture a coupler and a water-insoluble alcoholic compound having a hydroxy group forming an intramolecular hydrogen bond, wherein the alcoholic compound is represented by the following formula (A-1); formula (A-1) Ar-O-R 1 wherein Ar represents an aryl group; and R 1 represents an alkyl group having at least one hydroxy group; and the coupler is a magenta coupler represented by the following formula (M-1): wherein Z represents a non-metallic atomic group necessary to form a nitrogen-containing heterocyclic ring; X represents a hydrogen atom or a group capable of being released on reaction with an oxidation product of a colour developing agent; and R represents a hydrogen atom or a substituent. (2) A silver halide colour photographic material of (3) above, wherein the alcoholic compound is represented by the following formula (A-II); wherein R 2 represents a hydrogen atom, or a monovalent substituent; and n represents an integer of 1 to 5, provided that when n is 2, plural R 2 S are the same or different. Next, the invention will be explained in detail. The water insoluble alcoholic compound used in the invention has a hydroxy group which forms an intramolecular hydrogen bond, wherein the content of the hydroxy group which forms an intramolecular hydrogen bond is preferably 10% or more at 25°C based on the total content of the hydroxy group in the alcoholic compound. The "water insoluble alcoholic compound" herein referred to is defined to be an alcoholic compound having a water solubility at 25°C of less than 1% by weight. The water solubility is in terms of an amount by weight of a solute capable of being dissolved in 100 g of 25°C water. The content ratio of the hydroxy group which forms an intramolecular hydrogen bond to the total content of the hydroxy group in the alcoholic compound can be measured according to a method described in "Gouseijushi Kogyo, 35, 12 (1988). The method is as follows: The alcoholic compound is dissolved in dry carbon tetrachloride to obtain a solution having concentration of 10cc/liter, 20cc/liter, or 40cc/liter. One cc of each solution is incorporated into a cell of a rock salt solution, and subjected to infrared spectrometry. "Yukikagobutsu no supekutoru niyoru dotei", forth edition, pages 108-110, Silverstein et al., Tokyo Kagakudojin (1983) reads that in the spectra the free hydroxy group shows a sharp absorption in the range of from 3700 to 3600 cm -1 , and the hydroxy group which forms an intramolecular hydrogen bond shows a broad absorption in the range of from 3500 to 3200 cm -1 . The value of the optical density of each carbon tetrachloride solution minus the optical density of carbon tetrachloride itself leads to the absorption ratio (hydroxy group which forms an intramolecular hydrogen bond/hydroxy group which forms an intramolecular hydrogen bond + free hydroxy group) is obtained. The resulting ratios are plotted against alcoholic compound concentrations of solutions to obtain ratio/concentration graph. The resulting straight line intercept, extrapolated to a concentration of zero is defined as the intramolecular hydrogen bonding ratio (see Figs. 1 and 2).

(Light fastness) The samples were placed in a glass box, and exposed to a sun light through the glass for 3 months. The green light reflection density of the samples before and after the exposure were measured using a densitometer PDA-65. The degree of color fading (fading rate) was calculated according to the following equation: Fading rate (%) = (D 0 - D) × 100 / D 0 wherein D 0 represents a reflection density before the exposure, and D represents a reflection density after the exposure at 1.0 density portions before the exposure. (Color mixture) The unexposed samples were stored at 55°C and at 40%RH for 16 hours. Thereafter, the resulting samples were wedge exposed to a red light, and processed according to the above processing steps. The green light reflection density (D G/R ) of the processed samples were measured at portions having a red light reflection density of 1.0. The unexposed samples before the storage were similarly wedge exposed and processed, and the green light reflection density (D 0G/R ) of the processed samples were measured at portions having a red light reflection density of 1.0. The difference (ΔG G/R ) between (D G/R ) and (D 0G/R ) was used as a measure of color mixture.
