FIELD OF THE INVENTION 
The present invention relates to a color diffusion transfer photographic 
light-sensitive element, and more particularly to a color diffusion 
transfer photographic light-sensitive element containing a non-diffusible 
cyan dye image forming material capable of releasing a diffusible cyan dye 
or the precursor thereof under an alkaline condition. 
DESCRIPTION OF THE PRIOR ART 
In the color diffusion transfer process which uses a dye image forming 
material (hereinafter referred to as C.P.M.), a light-sensitive silver 
halide emulsion layer and a light-sensitive layer combined therewith 
containing C.P.M. are exposed imagewise to light, whereby a latent image 
is formed in the light-sensitive silver halide emulsion layer. This image 
is then processed with an alkaline processing composition in the presence 
of a silver halide developing agent, at which time the above 
light-sensitive layer and an image receiving layer are superposed. As a 
result of processing the oxide of the silver halide developing agent is 
produced, and then the foregoing C.P.M. is oxidized or reduced to thereby 
release a diffusible dye or a precursor thereof. The diffusible dye or the 
precursor thereof released from the C.P.M. is transferred by diffusion to 
the above image receiving layer to form a dye image. 
The above C.P.M. and color diffusion transfer processes using the C.P.M. 
are described in, e.g., U.S. Pat. Nos. 3,443,939, 3,443,940, 3,628,952, 
3,968,897, 3,728,113, 3,980,479, 4,053,312, 4,076,529, 4,139,379, 
4,139,389 and 4,199,354, Japanese Patent Publication Open to Public 
Inspection (hereinafter referred to as Japanese Patent O.P.I. Publication) 
Nos. 33826/1973, 54021/1979, 126331/1974, 99431/1974, 33141/1980, 
104343/1976, 85055/1982, 16131/1981, 71061/1981, 105738/1982, 142530/1981, 
164342/1981, 130927/1979, and the like. 
Examples of the cyan dye-releasable C.P.M. are described in Japanese Patent 
O.P.I. Publication Nos. 126331/1979, 109928/1976, 33141/1975, and the 
like. However, the use of the cyan dye-releasable C.P.M.s described in 
these publications have drawbacks; they have insufficient oxidation or 
reduction reactions, the dye released during processing diffuses too 
slowly so that too much time is required to obtain a final transfer image, 
and transferred image density is not sufficiently high. 
For example, U.S. Pat. No. 3,362,821 discloses a light-sensitive element 
which comprises a light-sensitive silver halide emulsion layer in 
combination with C.P.M., and a process control layer comprising a 
neutralizing layer and timing layer. The process control layer is arranged 
between the light-sensitive silver halide emulsion layer and the support; 
the neutralizing layer is present to terminate the development of the 
silver halide emulsion layer after a necessary developing period. The 
timing layer controls the lowering of the pH. 
According to a preferred embodiment of the above-described light-sensitive 
element, the element comprises a support having thereon in order: a 
polymeric acid layer, a timing layer or insoluble spacer layer, a cyan 
C.P.M.-containing layer, a red-sensitive silver halide emulsion layer, an 
interlayer, a magenta C.P.M.-containing layer, a green-sensitive silver 
halide emulsion layer, an interlayer, a yellow C.P.M.-containing layer, a 
blue-sensitive silver halide emulsion layer, and an overcoat layer. 
Such a light-sensitive element, after being exposed to light, is combined 
with an image receiving element, and processed in the presence of an 
alkaline processing composition to thereby obtain a transfer image. In 
such a process, an alkaline processing liquid permeates through the 
topmost layer downward in succession into the lower layers, thus 
commencing in order the developing of the respective layers. In this 
instance, the commencement of the development in the lowermost 
red-sensitive silver halide emulsion layer usually tends to be slightly 
later than that of the development in the upper blue-sensitive and 
green-sensitive silver halide emulsion layers. The release of the 
resulting cyan dye or the precursor thereof from the cyan 
C.P.M.-containing layer (in combination with the red-sensitive silver 
halide emulsion layer) is delayed, thus causing the color tone in the 
initial stage of the image transferred to the image receiving element to 
be lacking in cyan color. 
In the foregoing light-sensitive element, after a specified period of 
time--although differing according to the type--after, e.g., 20-60 
seconds, or not less than three minutes, the action of the process control 
layer arranged inside the light-sensitive layer reduces the pH to thereby 
stop the development. In this instance, necessary diffusion of the dye 
takes place, and after that, the element becomes stabilized. 
In an ordinary process control layer, a timing layer is used together with 
the neutralizing layer comprised of a polymeric acid polymer, the timing 
layer preventing premature lowering of pH to stop the development. 
Therefore, the developing time depends upon the time required for the 
alkaline composition to permeate into the timing layer. As the pH of the 
system is lowered, the development of the silver halide, the release of 
the dye from the C.P.M.-containing layer, and the diffusion of the dye in 
the course of being diffused are substantially stopped. In a color 
diffusion transfer photographic element having the foregoing process 
control layer, the lowering of the pH of the system occurs from the 
portions proximate to the process control layer. As a result, development 
is stopped, in order, from the red-sensitive silver halide emulsion layer. 
Accordingly, the foregoing light-sensitive element is disadvantageous 
because the development of the red-sensitive silver halide emulsion layer 
begins later than, but is stopped earlier than that of the other silver 
halide emulsion layers. 
As a means to solve these problems, it has been desired to use, in 
combination with the red-sensitive silver halide emulsion layer, a cyan 
C.P.M. whose oxidation or reduction reaction under alkaline conditions and 
the subsequent releasing reaction of the cyan dye or the precursor thereof 
are excellent over a wide pH range. The dye or the precursor thereof 
released from the C.P.M. should also have excellent diffusion 
characteristics in a binder such as gelatin. 
OBJECTS OF THE INVENTION 
It is an object of the present invention to provide a cyan C.P.M. capable 
of giving an excellent hue and having a stable cyan dye transfer color 
image. 
It is another object of the present invention to provide a cyan C.P.M. 
comprising a cyan dye portion which has a high oxidation or reduction 
reactivity over a wide pH range and which has an excellent 
transferability. 
It is a further object of the present invention to provide a color 
diffusion transfer photographic light-sensitive element containing a cyan 
C.P.M. capable of giving a relatively high-density cyan transfer dye image 
even in the presence of a relatively small quantity of a silver halide. 
It is still another object of the present invention to provide a color 
diffusion transfer photographic light-sensitive element containing a cyan 
C.P.M. capable of giving a high-density cyan transfer dye image even when 
positioned over a process control layer.

above objects can be accomplished by a photographic light-sensitive 
element comprising a support having thereon at least one light-sensitive 
silver halide emulsion layer and a cyan C.P.M. capable of releasing a

has, on the support thereof, a red-sensitive silver halide emulsion layer 
having a cooperative relation with a cyan or shifted cyan C.P.M., a 
green-sensitive silver halide emulsion layer having a cooperative relation 
with a magenta or shifted magenta C.P.M., and a blue-sensitive silver 
halide emulsion layer having a cooperative relation with a yellow or 
shifted yellow C.P.M. In the element, the above cyan C.P.M. is the 
compound of the present invention. 
One method of making a color photographic transfer image using of the 
photographic light-sensitive element of the invention comprises: 
(1) The multilayered light-sensitive element, after being imagewise 
exposed, is processed with an alkaline processing composition in the 
presence of a silver halide developing agent to develop the exposed area 
of the silver halide emulsion layers. The developing agent is thereby 
oxidized, and this oxidized developing agent cross-oxidizes with the 
C.P.M.s. 
(2) As a result of the imagewise exposure of the respective silver halide 
emulsion layers, imagewise-distributed diffusible dyes are formed. 
(3) To produce an image, the imagewise-distributed diffusible dyes diffuse 
into a dye image-receiving layer, and 
(4) the image receiving layer having the dye image thereon is then 
arbitrarily peeled apart from the light-sensitive element. 
In the above process, the light-sensitive element is developed or 
developing is begun in an arbitrary manner, so that it can be processed 
with an alkaline processing composition. 
U.S. Pat. Nos. 2,983,606, 3,485,628 and 3,907,563 disclose the processing 
of the light-sensitive element by immersing it in a viscous alkaline 
processing liquid for a specified period of time, taking it out of the 
liquid, and then superposing it upon an image-receiving layer. The 
preferred means for the application of the viscous processing composition 
is a rupturable container or pod containing the above composition. 
Generally, the processing composition used in the present invention 
contains a developing agent for use in development. However, where the 
developing agent is incorporated in either the light-sensitive material or 
the image receiving layer, the composition is allowed to be a plain 
alkaline liquid. In this instance, the alkaline liquid serves to activate 
the developing agent contained in the light-sensitive element or image 
receiving layer. 
Processing apparatus utilizing a non-viscous processing composition 
comprising a low-viscosity aqueous alkaline material is described in, 
e.g., U.S. Pat. No. 4,223,991. 
The present invention further provides a photographic film unit designed so 
as to pass between a pair of juxtaposed pressure-applying members in the 
processing of the unit. This film unit comprises (1) the above 
photographic element, (2) a dye image receiving layer, and (3) means to 
squeeze out the alkaline processing composition inside the film unit. 
The dye image-receiving layer inside the above unit may be provided on a 
separate support so that it, can be superposed on the light-sensitive 
element after an exposure. Such an image-receiving layer is generally 
known, which is described in, e.g., U.S. Pat. No. 3,362,819. In the case 
where means to squeeze out a processing composition is a rupturable 
container, generally, the container is arranged between the 
light-sensitive element and the image-receiving layer. A squeezing force 
is applied to the container with pressure-applying members to squeeze out 
and spread the content of the container between the outermost layers of 
the image-receiving layer and of the light-sensitive element. Such a 
processing system as the above may be designed so that the processing is 
accomplished inside a camera. 
After the processing, the dye image-receiving layer is peeled away from the 
light-sensitive element. The dye image-receiving layer inside the above 
film unit may also be provided so as to be integrated with a 
light-sensitive silver halide emulsion layer. Such an integrated 
image-receiving element-negative-type light-sensitive element unit is 
disclosed in U.S. Pat. No. 3,415,644. An example of this type comprises a 
light-sensitive element provided on an opaque support and an 
image-receiving layer provided on a separate transparent support that is 
located furthest from the opaque support. A film unit of this type has on 
the transparent support thereof, in order, preferably a neutralizing 
layer, timing layer, and then the dye image-receiving layer. The 
light-sensitive element, after being exposed to light, is superposed on 
the image-receiving layer coated on a transparent support with a 
rupturable container therebetween, the container containing an alkaline 
composition containing a reflective agent such as, e.g., TiO.sub.2. The 
container is ruptured by the pressure-applying members provided inside a 
camera, and when the film unit is drawn out from the camera, the 
processing composition is spread over the light-sensitive element. The 
spread processing composition develops the light-exposed silver halide 
emulsion layer, whereby a dye image is formed. The dye is then diffused 
into the image receiving layer, and a resulting image, with the opaque 
reflective layer as a background, can be observed through the transparent 
support. 
The light-sensitive element comprising an opaque support coated thereon 
with a neutralizing layer, timing layer and a single light-sensitive layer 
or a plurality of light-sensitive layers is disclosed in U.S. Pat. No. 
3,573,043. 
Further useful integrated film units for which the compound of the present 
invention is usable are described in U.S. Pat. Nos. 3,594,164, 3,594,165, 
3,647,437 and 3,635,707. 
The photographic light-sensitive element of the present invention can be 
used not only for the color diffusion transfer processes but also for 
ordinary color photographic processes. That is, after the processing of 
the above light-sensitive element and the image transfer, the imagewise 
distribution of the dye or dye-formable material as well as the developed 
silver can remain inside the element. If the residual silver and the 
silver halide are removed in an ordinary manner, e.g., in a bleach bath 
and then fixed in a fix bath, or in a bleach-fix bath, a color image 
consisting of residual non-diffusible compounds is obtained inside the 
element. The imagewise distribution of the dye or dye-formable material 
may also be diffused out from the element into these baths rather than 
remain inside the element. 
If a negative-type silver halide emulsion is used inside a certain 
preferred light-sensitive element, positive images, for example, 
reflective prints, color transparencies, or movie films, may be produced 
by this method. If a direct positive-type silver halide emulsion is used 
in such a light-sensitive element, negative color images can be produced. 
The term "color" used herein includes the so-called "black-and-white 
color." Accordingly, the light-sensitive material of this invention can be 
used advantageously in radiography. 
The film unit in the present invention can be used in making monochromatic 
or multicolor positive images. In a three-color system, the respective 
silver halide emulsion layers of a film material have cooperative 
relations with the C.P.M.s having principal spectral absorptions within 
the visible spectral regions to which the above respective emulsions are 
sensitive. That is, the blue-sensitive silver halide emulsion layer has an 
yellow C.P.M. having a cooperative relation therewith, the green-sensitive 
silver halide emulsion layer has a magenta C.P.M. having a cooperative 
relation therewith, and the red-sensitive silver halide emulsion layer has 
a cyan C.P.M. having a cooperative relation therewith. 
The C.P.M. to be combined with each of the respective silver halide 
emulsion layers may also be incorporated into the corresponding silver 
halide emulsion layer, or may also be incorporated into a layer adjacent 
to the emulsion layer. 
In the foregoing Formula (I), if the group represented by X is a 
hydrolyzable acyloxy group, the absorption spectrum of the azo dye is 
shifted toward relatively longer wavelength region. Dyes of this kind are 
called "shifted dyes," and the dye absorbs the light outside the region to 
which the silver halide emulsion layer combined with the dye is sensitive. 
U.S. Pat. No. 3,307,947 describes the use of certain shifted azo dye 
developing agents in connection with the above. 
The shifted C.P.M. of the present invention may be advantageously 
incorporated into the silver halide emulsion layer without deteriorating 
the speed of the emulsion layer. 
The above acyloxy group is hydrolyzed by an alkaline processing composition 
to thereby release a desired hue-providable cyan dye. 
The concentration of the compound, preferably alkali-cleavable by 
oxidation, used in the present invention may be changed over a wide range 
according to the specific compound used and the desired results. For 
example, the appropriate coating amount of the cyan C.P.M. of the present 
invention is from 1.times.10.sup.-5 to 1.times.10.sup.-2 mole/m.sup.2, and 
preferably from 2.times.10.sup.-4 to 2.times.10.sup.-3 mole/m.sup.2. 
Dispersion of the cyan C.P.M. of the present invention into the 
light-sensitive element may be made by any of conventionally known various 
C.P.M. dispersion methods. Typical dispersion methods include: 
(1) The cyan C.P.M. of the present invention is dissolved into a 
substantially water-insoluble, high-boiling solvent, and then finely 
dispersed into a hydrophilic protective colloid. Particularly useful 
high-boiling solvents include N-n-butylacetoanilide, diethyl-lauroylamide, 
dibutyl-lauroylamide, dibutyl phthalate, tricresyl phosphate, 
N-dodecyl-pyrolidone, and the like. 
In order to facilitate the above dissolving, low-boiling or water-soluble 
organic solvents may be used. The low-boiling solvent includes ethyl 
acetate, methyl acetate, cyclohexanone, acetone, methanol, ethanol, 
tetrahydrofuran, etc.; the water-soluble organic solvent includes 
2-methoxyethanol, dimethylformaldehyde, etc. These low-boiling solvents 
and water-soluble organic solvents can be removed by water or during the 
course of drying. 
(2) The cyan C.P.M. of the present invention is dissolved into a 
water-miscible organic solvent, into which a fillable polymer latex and a 
sufficient amount of water to cause the cyan DRR compound in the solution 
to become insoluble is added slowly, whereby the cyan C.P.M. is 
incorporated into the fillable polymer latex particles. 
The water-miscible organic solvent and the fillable polymer latex are 
described in detail in the foregoing Japanese Patent O.P.I. Publication 
Nos. 59942/1976 and 59943/1976. 
(3) The cyan C.P.M. of the present invention is mechanically fine-grained 
by use of a sand grinder or a colloid mill, and then dispersed into a 
hydrophilic colloid. 
(4) The cyan C.P.M. of the present invention is dissolved into a 
water-miscible organic solvent, and precipitated into water, preferably in 
the presence of a surfactant, and then the precipitate is dispersed into a 
hydrophilic colloid. This is the method described in, e.g., Japanese 
Patent O.P.I. Publication No. 139532/1978. 
(5) The cyan C.P.M. of the present invention is dissolved together with a 
polymer into an aqueous alkaline solution, and the pH thereof is adjusted 
with use of an acid to thereby precipitate the cyan C.P.M. to be dispersed 
into a hydrophilic colloid. 
The present invention allows the arbitrary use of various methods without 
being limited to the above-described methods. 
The above hydrophilic protective colloid usable in the present invention 
includes, e.g., hydrophilic film-formable natural or synthetic polymer, 
such as, e.g., gelatin or polyvinyl alcohol (these suitably permit the 
permeation of an alkaline processing liquid), which is used as a 
dispersion medium of the cyan C.P.M. and coated to form a layer. 
With respect to the compound of the present invention, various silver 
halide developing agents can be used in the invention. If the Car group 
used is any of those Car groups of Formulas (II)-(V), as long as the 
developing agent cross-oxidizes with the C.P.M. used, any silver halide 
developing agent can be used. The developing agent may also be used inside 
the light-sensitive element, in which case, it should be activated by an 
alkaline processing composition. Particular examples of the usable 
developing agents include hydroquinone, aminophenols such as, e.g., 
N-methylaminophenol, phenidone (1-phenyl-3-pyrazolidinone), dimezone 
(1-phenyl-4,4-dimethyl-3-pyrazolidinone), 
1-phenyl-4-methyl-4-hydroxymethyl-3-pyrazolidinone, 
N,N-diethyl-p-phenylenediamine, 3-methyl-N,N-diethyl-p-phenylenediamine, 
and 3-methoxy-N,N-diethyl-p-phenylendiamine. 
Among the above, black-and-white-type light-sensitive material developing 
agents are advantageous because they do not or only slightly stain the dye 
image-receiving layer. In the preferred example of the present invention, 
the silver halide developing agent used in the method according to the 
present invention is oxidized during development and concurrently reduces 
the silver halide into metallic silver. The oxidized developing agent 
cross-oxidizes the C.P.M. The cross-oxidized product subsequently 
undergoes alkali hydrolysis to thereby release a diffusible dye in an 
imagewise distribution. The resulting dye then diffuses into the 
image-receiving layer to produce a dye image. 
In the color diffusion transfer process which uses any of the positive 
image-formable dye-releasable compounds having Formulas (VI) to (XI), the 
reducing agent is present as the inverse function of the silver halide 
development, and by the reaction between the reducing agent and a 
ballasted C.P.M. having any of Formulas (VI) to (XI) under alkaline 
conditions, a diffusible dye is released. The reducing agent (which 
reduces the C.P.M., i.e., an electron donor), and the precursor thereof 
such as benz-iso-oxazolones, .beta.-diketones, saccharins, lactones, 
protohydroquinones, ascorbic acids, aminophenols, aminonaphthols, 
hydroquinones, or the like, are used in combination with the C.P.M. Such 
compounds are known from, e.g., Research Disclosure Nos. 19429 and 19507, 
and Japanese Patent O.P.I. Publication No. 138736/1981. Further, 
particularly favorable electron donators are described in Japanese Patent 
O.P.I. Publication No. 150846/1982. 
In the case of using a negative image-formable dye releasable compound in 
accordance with the present invention, a negative-type or direct 
positive-type silver halide emulsion layer may be used. If the silver 
halide emulsion used forms a direct positive silver image, like a direct 
positive internal image emulsion or reversal emulsion, a positive image 
can be obtained in the dye image-receiving layer. After to light exposure 
to light of the film unit to light, an alkaline processing composition 
permeates into all the layers of the unit, and commences the development 
of the unexposed areas of the light-sensitive silver halide emulsion 
layers. The developing agent present inside the film unit (because the 
silver halide emulsion is of the direct positive type) develops the 
unexposed areas of the respective silver halide emulsion layers, so that 
the developing agent is oxidized imagewise corresponding to the unexposed 
areas of the direct positive-type silver halide emulsion layers. The 
oxidized developing agent subsequently cross-oxidizes the dye-releasable 
compound or, in the preferred example of the present invention, performs a 
base-catalytic reaction to imagewise release the dye according to the 
imagewise exposure of the respective silver halide emulsion layers. At 
least part of the imagewise distribution of the diffusible dye diffuses 
into the image-receiving layer, thus forming a positive image. After 
contact with an alkaline processing composition, a pH lowering layer 
lowers the pH of the film unit or of the image-receiving layer to 
stabilize the image. An internal latent image-type silver halide emulsion 
that forms a latent image principally inside the silver halide particles 
thereof is also useful as the direct positive emulsion; such an emulsion 
is described in Davey et al. U.S. Pat. Nos. 2,592,250 and 3,761,276. 
The internal latent image-type silver halide emulsion, when processed in 
the presence of a fogging agent, directly yields a positive silver image. 
Examples of such fogging agents include those hydrazines as described in 
U.S. Pat. Nos. 2,588,982 and 2,563,785; those hydrazones as described in 
U.S. Pat. No. 3,227,552; those hydrazones as described in U.S. Pat. No. 
3,615,615; quaternary salts; and those hydrazone-containing polymethine 
dyes as described in U.S. Pat. No. 3,718,470; and mixtures of these 
compounds. 
Other direct positive silver halide emulsions useful for the above examples 
are such silver halide emulsions chemically fogged in advance by use of a 
reducing agent or fogged in advance almost up to the point of maximum 
potential density of reversal image by exposing to radiant light. 
The above emulsions are described in pages 261-297 of "The Theory of The 
Photographic Process" by Mees (published by McMillan Co. N.Y. in 1942). 
Typical methods for preparing such emulsions are described in U.S. Pat. 
Nos. 3,367,778, 3,501,305, 3,501,306 and 3,501,307. 
Other examples for which the image formable compounds according to the 
present invention may be used include those techniques as described in 
U.S. Pat. Nos. 3,227,550, 3,227,551, 3,227,552 and 3,364,022. 
Negative-type silver halide emulsions useful for certain examples of the 
present invention include, e.g., silver chloride, silver chlorobromide, 
silver iodobromide, silver chloroiodobromide emulsions and mixtures of 
these silver halide emulsions. These emulsions may be used in the 
coarse-grained or fine-grained form, and prepared in various manners of 
the prior art. 
Such emulsions include, for example, single-jet emulsions as described by 
Trivelli & Smith in "The Photographic Journal" LXXIX, May 1939, pp. 
330-358; double-jet emulsions, e.g., Lippmann emulsion, ammoniacal 
emulsion, and those emulsions ripened with use of thiocyanate or 
thioether, as described in U.S. Pat. Nos. 2,222,264, 3,320,069 and 
3,574,628. These emulsions can also be monodispersed regular particle 
emulsions as described by Klein and Moisar in the "Journal of the 
Photographic Science" Vol. 12, No. 5, Sept./Oct. 1964, pp. 242-251. 
Another example of the present invention uses the image reversing method 
disclosed in the 1st-41st lines in p. 19 of U.K. Pat. No. 904,364. In this 
system, the dye-providable compound of the present invention is used 
together with the physical development nucleus of the layer adjacent to 
the light-sensitive silver halide negative-type emulsion layer. 
This film unit contains a silver halide solvent. The film unit is, 
preferably, provided with a rupturable container containing an alkaline 
processing composition. 
The silver halide emulsion layers of a color film according to the present 
invention are coated in an ordinary order, i.e., from the incident light 
side in the order of a blue-sensitive silver halide emulsion layer, 
green-sensitive silver halide emulsion layer, and red-sensitive silver 
halide emulsion layer. However, the order may be changed according to 
desired purposes. 
If necessary, a yellow dye layer or yellow colloidal layer may be 
interposed between the blue-sensitive silver halide emulsion layer and the 
green-sensitive silver halide emulsion layer. 
The rupturable container used as part of the integrated film unit of the 
present invention is of the type as described in U.S. Pat. Nos. 2,543,161, 
2,643,886, 2,653,732, 2,724,051, 3,056,492, 3,056,491 and 3,152,515. 
In the color film unit according to the present invention, the respective 
C.P.M.-containing silver halide emulsion layers or the respective silver 
halide emulsion layers provided with their adjacent layers containing 
C.P.M. are separated from one another by any of a number of materials such 
as gelatin, calcium alginate, or those as described in U.S. Pat. No. 
3,384,483, polymer materials such as polyvinylamide as disclosed in U.S. 
Pat. No. 3,421,892, or those as described in French Patent No. 2,028,236, 
and U.S. Pat. Nos. 2,992,104, 3,043,692, 3,044,873, 3,061,428, 3,069,263, 
3,069,264, 3,121,011 and 3,427,158. 
Generally speaking, the silver halide emulsion layer of the present 
invention is one produced by dispersing a light-sensitive silver halide 
into gelatin, having a thickness of about 0.6 to 6 microns. A dye 
image-providable material is dispersed into an aqueous alkaline 
solution-permeable polymer binder such as gelatin which, as a separating 
layer, has a thickness of about 1 to 7 microns. An alkaline 
solution-permeable polymer intermediate layer, such as of gelatin, has a 
thickness of about 1 to 5 microns. These thicknesses, of course, are 
approximate values, so that for commercial products, these thicknesses are 
allowed to be changed. 
As long as it is a mordant or has a fixable function, any arbitrary 
material can be used as the image-receiving layer of the present 
invention. It goes without saying that selection of any particular 
material depends on the dye to be mordanted. The usable mordant includes 
such basic polymer mordants as, e.g., polymers of amonoguanidine 
derivatives of vinylmethyl ketone; those as described in, e.g., U.S. Pat. 
No. 2,882,156; and such basic polymer mordants as described in, e.g., U.S. 
Pat. Nos. 3,625,694, 3,709,690 and 3,898,088. In addition, the same are 
also described in U.S. Pat. Nos. 3,958,995 and 3,859,096, and Research 
Disclosure No. 15162 (1976). 
Generally, as the image-receiving layer, satisfactory results are obtained 
by use of a transparent, alkaline solution-permeable image-receiving layer 
having a thickness of about 0.25-0.40 mil. The thickness is allowed to be 
changed according to desired results. The image-receiving layer may 
contain an ultraviolet absorbing agent to prevent possible discoloration 
of the mordanted dye image by ultraviolet rays, and further may contain a 
brightening agent such as, e.g., stilbene, coumarin, triazine, oxazole, or 
the like, and a dye stabilizer such as, e.g., chromanol, alkylphenol, or 
the like. 
The stability of the transfer image may be generally increased by applying 
a pH lowering agent to the dye image-receiving portion of the film unit of 
the present invention. Generally, this pH lowering agent functions to 
rapidly lower the pH of the image layer after the imbibition thereof. For 
example, good results can be obtained by use of such polymer acids or 
solid acids or metallic salts as disclosed in U.S. Pat. No. 3,362,819, or 
zinc acetate, zinc sulfate or magnesium oxalate as disclosed in U.S. Pat. 
No. 2,584,030. Such pH lowering agents are capable of lowering the pH of 
the film unit during the period between the commencement of and completion 
of the development. Further, during the development period, it also 
substantially lowers the transfer rate of the dye to thereby stabilize the 
dye image. 
If an inert timing layer or a spacer layer is used over the above pH 
lowering layer, the lowering of the pH can be delayed for the time 
necessary for the alkali to pass through the spacer layer to be diffused, 
i.e., the pH lowering speed can be controlled. As such a timing layer, 
gelatin, polyvinyl alcohol or any of those as disclosed in U.S. Pat. No. 
3,455,686 may be arbitrarily used. 
The timing layer is effective to even out the reaction rate which otherwise 
changes with temperature. For example, the timing layer, when the 
imbibition is made at a temperature higher than normal temperature, e.g., 
at a temperature between 35.degree. C. and 38.degree. C., prevents the 
speed up of the pH lowering. 
The thickness of the timing layer is normally from 0.1 to 0.7 mil. A 
particularly satisfactory timing layer is comprised of a hydrolyzable 
polymer that is slowly hydrolyzed by a processing composition or of a 
collective of such polymers. Examples of such hydrolyzable polymers 
include polyvinyl acetates, polyamides and cellulose esters. Other 
examples of such timing layers and the functions thereof are described in 
detail in Japanese Patent O.P.I. Publication Nos. 54341/1980, 69629/1981, 
6842/1982, 6843/1982 and 60332/1982, and Japanese Patent Application No. 
65445/1981. 
The alkaline processing composition for use in the present invention is a 
solution containing an alkaline material such as sodium hydroxide, sodium 
carbonate, etc., or an aqueous amine solution containing an amine such as 
diethylamine. The pH of the solution is preferably not less than 10. The 
solution preferably contains the foregoing developing agent. 
This solution may also contain a viscosity-increasing compound such as a 
water-soluble ether that is inert to an alkaline solution, an 
alkali-metallic salt of hydroxyethyl cellulose or of carboxymethyl 
cellulose, or sodium carboxymethyl cellulose. The viscosity-increasing 
compound, in an amount of 1-5% by weight based to the processing 
composition, increases the viscosity of the processing composition to the 
preferred viscosity range of 100 cp cps-200,000 cp cps. In a certain 
example of the present invention, an opacifying agent such as, e.g., 
TiO.sub.2, carbon black and/or a pH indicator dye may be added to the 
processing composition. 
The alkaline processing composition usable in the present invention is 
packed in a rupturable container, whereby the processing composition can 
be conveniently incorporated into the film unit. 
An alkali-permeable, substantially opaque light-reflective layer usable in 
a certain example of the film unit of the present invention is generally 
comprised of an arbitrary opacifying agent dispersed in a binder. The 
particularly preferred embodiment is a white light-reflective layer 
because it enables the transferred dye image to have a beautiful look, and 
it has an optically preferred nature for the reflection of the incident 
radiant light. The preferred opacifying agent is titanium dioxide, which 
may be dispersed into gelatin or polyvinyl alcohol. 
Brightening agents such as stilbene, coumarin or oxazole may, if necessary, 
be added to the light-reflective layer. If the opacity of the 
light-reflective layer should be increased, a black opacifying agent such 
as, e.g., carbon black or nigrosine dye may be incorporated into a 
different layer adjacent to the above light-reflective layer. 
The support material usable for the light-sensitive element and the 
image-receiving element is a flexible material in sheet form such as 
cellulose nitrate film; cellulose acetate film, poly(vinyl acetal) film, 
polystyrene film; poly(ethylene terephthalate) film, polycarbonate film; 
poly-.alpha.-olefin film such as, e.g., polyethylene or polypropylene 
film; or the like film; or resinous material or paper--preferably 
poly-.alpha.-olefin-coated paper. 
The silver halide emulsion and the techniques relating thereto useful for 
the present invention are known to those skilled in the art. They are 
described in Research Disclosure No. 9232 (1971). 
The term "nondiffusibility" used herein means the generally applied meaning 
to this photographic term. It is applied to materials which do not migrate 
or wander through an organic colloidal layer, such as, e.g., a gelatin 
layer, when the photographic element of the present invention is processed 
in an alkaline medium having a pH of preferably not less than 5. The term 
"diffusibility" has an opposite meaning to "nondiffusibility" above. 
"Diffusibility" is applied to materials having the ability to effectively 
diffuse through the colloidal layer of the photographic element in an 
alkaline medium. 
Methods of producing compounds having Formula (I) will be described below: 
##STR33## 
Synthesis of Intermediate [I] 
200 g of .beta.-methoxyethylamine are added to 1.3 liters of chloroform, 
and to the mixture are added 150 g of 
5-acetylamino-1-acetoxy-2-chlorosulfonyl-naphthalene at a temperature of 
not more than 30.degree. C. After the addition, the mixture is heated to 
50.degree. C. and stirred for a period of two hours, and then the solvent 
is distilled off under reduced pressure, whereby a solid is obtained. 
Synthesis of Intermediate [II] 
150 g of sodium hydroxide are dissolved into one liter of water, to which 
solution is added all the above-obtained Intermediate [I], and the mixture 
is refluxed by heating for a period of 6 hours. After natural cooling, the 
deposited crystals are filtered, and then dissolved into 2 liters of 
water, to which is dropwise added acetic acid to adjust the pH to 4. The 
deposited crystals are filtered, thereby obtaining an objective product. 
Yield: 120 g, Melting point: 111.degree.-113.degree. C. 
Synthesis of Intermediate [III] 
100 g of the above Intermediate [II] are dissolved into 800 ml of pyridine. 
92 g of N,N-dimethylaminosulfonyl chloride are added to the solution 
dropwise at a temperature of from 20.degree. to 30.degree. C. The mixture 
is stirred over a period of 24 hours at room temperature and 100 ml of 
water are added thereto. After a further two-hour stirring, the mixture is 
poured into 5 liters of iced water containing one liter of hydrochloric 
acid; the deposited crystals are filtered and washed with two liters of 
water. The resulting crystals, after drying, are dissolved into 800 ml of 
chloroform; the partially undissolved substance is removed by filtering 
with diatomaceous earth, and the filtrate is concentrated to 400 ml. To 
the concentrated liquid 200 ml of n-hexane are added to deposit the 
crystals. The crystals are filtered and washed with a chloroform-n-hexane 
liquid (1:1) mixture, and then dried. Yield: 70 g, Melting point: 
125.degree.-126.degree. C. 
Synthesis of Intermediate [IV] 
To 50 ml of concentrated sulfuric acid, 8.5 g of sodium nitrite are added 
in small amounts at a temperature of not more than 25.degree. C. The 
mixture is heated to 70.degree. C. and the heating is continued for 15 
minutes. The mixture is then cooled, to which are added 100 ml of glacial 
acetic acid. 43 g of 2-(4-sulfophenethyl)ethylsulfonyl-4-nitroaniline 
(Japanese Patent O.P.I. Publication No. 33141/1980) are added, and the 
resulting solution is stirred for three hours at 10.degree.-15.degree. C. 
to homogenize the solution. The solution is then diluted, with cooling, by 
adding 100 ml of glacial acetic acid and 150 ml of iced water. A small 
quantity of urea is then added to decompose excess sodium nitrite, thereby 
producing a diazonium salt solution. 
46 g of Intermediate [III] are dissolved into a liquid mixture of 300 ml of 
methanol with 50 ml of glacial acetic acid. To this, 20 g of potassium 
acetate and 50 ml of water are added to prepare a coupler solution. This 
coupler solution is cooled to 5.degree.-10.degree. C. The foregoing 
diazonium salt solution and 120 g of potassium acetate are added 
simultaneously, in small amounts, to carry out a diazo coupling. After the 
addition, the system is stirred for two hours at room temperature to 
deposit dye crystals, which are filtered and washed, first with glacial 
acetic acid and then with methanol, thereby obtaining the objective 
product. Yield: 130 g. 
Synthesis of Intermediate [V] 
25 g of Intermediate [IV] is dispersed into a mixture of 300 ml of 
acetonitrile with 40 ml of dimethylformamide. To the mixture, 35 g of 
oxalic chloride are added dropwise with cooling to maintain a temperature 
below 15.degree. C. The liquid is stirred at a temperature of from 
15.degree. to 20.degree. C. for an hour, and then poured into 2 liters of 
iced water to deposit crystals, which are subsequently filtered and 
sufficiently washed with cold water, and then dried under reduced pressure 
in a phosphorus pentaoxide desiccator. Yield: 17 g. 
Synthesis of Exemplified Compound 7 
11.2 g of 2-phenyl-3-amino-5-octadecylsuccinimido-indole (Japanese Patent 
O.P.I. Publication No. 85055/1982) is suspended in 200 ml of chloroform, 
to which are added 16 g of Intermediate [V] and 10 ml of pyridine are then 
slowly added dropwise. This mixture is refluxed by heating for 2 hours, 
and then 5 ml of water and 100 ml of methanol are added thereto. The 
resulting mixture is further refluxed for 3 hours, and subsequently heated 
under normal pressure to distill off the chloroform-methanol azeotropic 
mixture. In this instance, methanol should be added from time to time to 
keep at least 200 ml of solvent present. When the chloroform is completely 
substituted by methanol, 12 ml of concentrated hydrochloric acid are added 
to the system, which is then cooled. The deposited precipitate is filtered 
and washed with methanol and then with water. Subsequently, the solid is 
dissolved into ethyl acetate, and then isolated and refined by silica gel 
column chromatography. Yield: 13.2 g, Melting point: 
195.degree.-198.degree. C. 
##STR34## 
Synthesis of Intermediate [I] 
To one liter of chloroform are added 12 g of glycine-ethyl hydrochloride 
and 110 g of triethylamine. To this are added 120 g of 
5-acetylamino-1-acetoxy-2-chlorosulfonylnaphthalene at a temperature of 
not more than 30.degree. C. After the addition, the reaction liquid is 
heated to 45.degree.-50.degree. C. for two hours, and then poured into 1.2 
liters of iced water containing 60 ml of concentrated hydrochloric acid to 
thereby remove excess triethylamine in the hydrochloride form. The liquid 
is subsequently separated into a chloroform phase and water phase, and the 
chloroform is concentrated under reduced pressure, whereby 136 g of a 
solid are obtained. 
Synthesis of Intermediate [II] 
120 g of sodium hydroxide are dissolved into 0.8 liter of water and to the 
solution are added 122 g of the foregoing Intermediate [I]. The mixture is 
refluxed by heating for 6 hours. After natural cooling, the liquid is 
poured into ice water containing 250 ml of concentrated hydrochloric acid 
and 2 kg of ice. Acetic acid is added to adjust the pH to 4.0 to thereby 
deposit a precipitate. This precipitate is filtered and then dried at a 
temperature of not more than 50.degree. C. Yield: 62 g, Melting point: 
185.degree.-189.degree. C. 
Synthesis of Intermediate [III] 
60 g of Intermediate [II] are dissolved into 500 ml of pyridine, and 52 g 
of N,N-dimethylaminosulfonyl chloride are added dropwise, at 20.degree. to 
30.degree. C. to the solution. The reaction takes place at 
45.degree.-50.degree. C. for 6 hours. After completion of the reaction, 
the reaction liquid is poured into 2.5 liters of ice water containing 500 
ml of concentrated hydrochloric acid, and the pH thereof is adjusted by 
use of acetic acid to 4.0, thereby obtaining a precipitate. The 
precipitate is filtered and then dried at a temperature of not more than

are added, and the mixture is then refluxed by heating for 8 hours. The 
reaction liquid, after being allowed to stand overnight, is poured into 
ice water containing potassium hydrogencarbonate, thereby obtaining a 
precipitate. The precipitate is filtered, washed with water, and then 
dried. Yield: 53 g, Melting point: 135.degree.-139.degree. C. 
Synthesis of Intermediate [V] 
8.1 g of sodium nitrite is added in small amounts at a temperature of not 
more than 15.degree. C. to 52 ml of concentrated sulfuric acid. The 
mixture is dissolved by heating for 15 minutes at 60.degree.-65.degree. C. 
This is cooled and to it are added, at a temperature of not more than 
25.degree. C., 85 ml of glacial acetic acid 40.8 g of 
2-(4-sulfophenethyl)ethylsulfonyl-nitroaniline (Japanese Patent O.P.I. 
Publication No. 33141/1980) are added at a temperature of 
10.degree.-15.degree. C. This mixture is then stirred for three hours at 
10.degree.-15.degree. C. to homogenize the solution. The solution is 
cooled and then diluted by the addition of 100 ml of glacial acetic acid 
and 150 ml of ice water. A small quantity of urea is added to decompose 
excess sodium nitrite, thereby preparing a diazonium salt solution. 
43.1 g of Intermediate [IV] is dissolved into a mixture of 280 ml of 
methanol with 50 ml of acetic acid, and to it are added 20 g of potassium 
acetate and 50 ml of water, thereby preparing a coupler solution. 
Simultaneously, with cooling to 5.degree. to 10.degree. C. the above 
diazonium salt solution and 110 g of potassium acetate are added in small 
amounts to the coupler solution to thereby carry out a diazo-coupling 
reaction. After the addition, the reaction system is stirred at room 
temperature for two hours to deposit a dye. The deposited dye is filtered, 
washed with glacial acetic acid and then with methanol to thereby obtain 
the objective product. Yield: 133 g. 
Synthesis of Intermediate [VI] 
To 750 ml of chloroform are added 10.5 ml of N,N-dimethylformamide. The 
mixture is cooled to less than 10.degree. C., and 13.2 ml of phosphorus 
oxychloride are added dropwise little by little. 50 g of Intermediate [V] 
is added in small amounts. After the addition, the mixture is stirred for 
three hours at about 45.degree. C. Thin layer chromatography is used to 
make sure of the vanishing of Intermediate [V], and after that the liquid 
is cooled to 15.degree. C. to deposit crystals. The crystals are filtered 
and washed with a dried, and cold chloroform twice then dried under 
reduced pressure. Yield: 47 g. 
Synthesis of Intermediate [VII] 
11.1 g of 2-phenyl-3-amino-5-octadecylsuccinimido-indole (Japanese Patent 
O.P.I. Publication No. 85055/1982) are suspended in 150 ml of dried 
acetonitrile, and to it are added 20 ml of pyridine and 32 g of 
Intermediate [IV]. The reaction of the liquid takes place at 40.degree. C. 
for three hours. After completion of the reaction, the liquid is cooled to 
about 15.degree. C. to deposit a precipitate. The precipitate is filtered 
off, and the filtrate is poured into 800 ml of ice water containing 22 ml 
of concentrated hydrochloric acid to deposit crystals. The crystals are

Into 200 ml of deoxidized N,N-dimethylformamide are dissolved 10.9 g of 
Intermediate [VII], and to the solution are added 100 ml of deoxidized 
methanol. The mixture is then cooled to less than 10.degree. C. 
Aside from this, 10 g of sodium hydroxide are dissolved into 50 ml of 
water, and to it are further added 100 ml of methanol resulting in a 
mixture which is sufficiently deoxidized. 
This solution is also cooled to less than 10.degree. C., and then is added 
dropwise, under a nitrogen flow, to the foregoing Intermediate 
[VII]-containing solution. The mixture is stirred under the nitrogen 
atmosphere until conversion of Intermediate [VII] is confirmed by thin 
layer chromatography. The liquid is then poured into 1.5 liters of ice 
water containing 40 ml of concentrated hydrochloric acid to deposit a 
precipitate. The precipitate is filtered, collected and then dried. Yield: 
6.5 g. 
Examples of the present invention will be illustrated in detail below, but 
the present invention is not limited thereto.

EXAMPLE 1 
Table 1 shows the results obtained by measuring, in the following manners, 
the spectral absorption characteristic and the stability to light of the 
dye released from the cyan dye image formable material of the present 
invention. 
(1) Spectral Absorption Characteristic: The released dye is used to dye a 
mordant layer provided in a transparent support. The spectral absorption 
spectrum of the film strip is measured by means of a spectrophotometer. 
The maximum absorption wavelength (.lambda.max) and the half-value width 
(the wavelength range of the absorption spectrum having the density 
corresponding to a half of the maximum absorption density) thereby 
obtained. 
(2) Stability to Light of the Dye: The dyed film strip is subjected to 
strong light irradiation to examine its stability. That is, the dyed film 
strip having a transmission density of from 1.0 to 1.5, is irradiated over 
a period of 24 hours by a 6000 W xenon lamp. The irradiation light 
intensity is 60,000 luxes. The optical densities Do and D in .lambda.max 
before and after the irradiation were measured, and the dye's residual 
percentage (%)=(D/Do).times.100 was found. The dyes used in the 
measurement are those compounds having the following formula with those 
substituents as shown in Table 1. 
##STR35## 
The mordant used is a 
styrene-N,N-dimethyl-N-benzyl-N-p-(methacroylaminophenyl)methyl-ammonium 
chloride-divinylbenzene ternary copolymer (molar ratio: 48:48:4).

As can be understood from the above table, the dyes (No. 1 to No. 10) from 
the DRR compounds of the present invention have excellent characteristics 
as the cyan dye as compared to the comparative dyes (No. 11 to No. 13). 
EXAMPLE 2 
The following layers were coated in the described order on a 150.mu.-thick 
transparent polyethylene terephthalate film support, thereby preparing a 
multilayered monochromatic light-sensitive element. 
(1) Image-receiving layer containing gelatin (2.5 g/m.sup.2) and 
poly(styrene-co-vinyl-benzyl 
chloride-co-N-benzyl-N,N-dimethyl-N-vinyl-benzyl-ammonium 
chloride-co-divinylbenzene) (molar ratio: 4.90:0.49:4.41:0.2) (2.5 
g/m.sup.2). 
(2) White reflective layer containing titanium dioxide (22 g/m.sup.2) and 
gelatin (2.2 g/m.sup.2). 
(3) Light-shield layer containing carbon black (2.8 g/m.sup.2) and gelatin 
(1.8 g/m.sup.2). 
(4) Cyan dye image forming material layer containing a cyan DRR compound 
(Exemplified Compound 7) of the invention (0.6 g/m.sup.2), 
N,N-diethyl-laurylamide (1.0 g/m.sup.2), and gelatin (2.5 g/m.sup.2). 
(5) Red-sensitive emulsion layer containing a red-sensitive internal latent 
image-type direct positive silver bromide emulsion (silver equivalent of 
0.75 g/m.sup.2), potassium 2-octadecyl-hydroquinone-5-sulfonate (0.08 
g/m.sup.2), 1-[4-(2-formyl-hydrazine)phenyl]-3-phenyl-thiourea (2.5 mg per 
mole of silver), and gelatin (1.65 g/m.sup.2). 
(6) Protective layer containing mucochloric acid (100 mg/m.sup.2) and 
gelatin (1 g/m.sup.2). 
In the above, the C.P.M.-dispersed liquid was prepared in the following 
manner: 
One gram of the C.P.M. was dissolved into 3 ml of ethyl acetate, and the 
N,N-diethyl-laurylamide was added to the solution. The resulting solution 
was emulsified to be dispersed into a 10% aqueous gelatin solution 
containing 0.24 g of Alkanol XC (a product of DuPont). 
If the C.P.M. is less-soluble in ethyl acetate, cyclohexanone is used. 
Subsequently, on a 100 .mu.m-thick transparent polyethylene terephthalate 
film support, the following layers were coated in the described order, 
thereby preparing a processing sheet. 
(1) Neutralizing layer containing an acrylic acid-butyl acrylate copolymer 
(70/30% by weight) (22 g/m.sup.2). 
(2) Timing layer comprising a mixture (80:20) of poly(vinylidene 
chloride-co-itaconic acid-co-methyl acrylate)latex (55/6/39% by weight) 
with an acid/butyl ester (30/70% by weight) lactone polymer produced by 
the hydrolysis, lactonization, and partial esterification of a methacryl 
alcohol-maleic anhydride copolymer with 1-butanol. 
The foregoing multilayered monochromatic light-sensitive element is 
subjected to a given exposure through an optical silver 30-step wedge with 
each step having a density difference of 0.10. The above processing sheet 
is then superposed on the light-sensitive element, and further a pod 
containing the following processing composition is attached to between the 
processing sheet and element, thus preparing a film unit. The film unit is 
then passed between a pair of juxtaposed pressure rollers with a gap of 
about 75.mu. therebetween to thereby rupture the pod to spread the 
contents thereof into and between the above light-sensitive element and 
the processing sheet. 
The processing composition used herein is as follows: 
______________________________________ 
Potassium hydroxide 56.0 g 
Sodium sulfite 2.0 g 
4-hydroxymethyl-4-methyl-1- 
8.0 g 
phenyl-3-pyrazolidine 
5-methylbenzotriazole 2.8 g 
Carbon Black (Raven-450, manufac-

Sodium carboxymethyl cellulose (high 
50.0 g 
viscous type, manufactured by Tokyo 
Kasei) 
Benzyl alcohol 1.5 ml 
Distilled water to make 
1000.0 ml 
______________________________________ 
After the processing, the produced dye image was observed through the 
transparent support of the light-sensitive element. The reflection 
densities of the dye image were measured in succession through a red 
filter (.lambda.max=644 nm) by a photoelectric densitometer. 
The following Table 2 shows the time (t 0.5) required to reach the 50% and 
the time (t 0.8) required to reach the 80% of the maximum density (Dmax). 
Dmax is obtained 15 minutes after the commencement of the processing. The 
lengths of these periods of time will be criteria for the image forming 
speed. In addition, the temperature applied during the foregoing 
processing was 25.degree. C. 
In the foregoing light-sensitive element, the sample prepared with use of 
Exemplified Compound (7) of the present invention in the 4th layer was 
regarded as Sample A. The other samples are prepared in quite the same 
manner as in Sample A with the exception that Exemplified Compounds (8), 
(11) and (15) were used in place of the Exemplified Compound (7) to yield 
Sample B, Sample C, and Sample D, respectively. Further, as comparative 
compounds, the following Compound (1) and Compound (2) were used to 
prepare Sample E and Sample F, respectively.

Subsequently, each of the above light-sensitive element samples was 
superposed upon an image-receiving sheet prepared by coating the following 
layers in the described order on an opaque paper support. 
Image Receiving Sheet 
(1) Dye image-receivable layer comprising a 
styrene-N,N-dimethyl-N-benzyl-N-p-(methacroylaminophenyl)methyl-ammonium 
chloride-divinyl benzene ternary copolymer (molar ratio: 48:48:4) (2.7

(3) Protective layer of gelatin (0.65 g/m.sup.2). 
(4) Overcoat layer comprised of gelatin (0.27 g/m.sup.2) and silica (1.4

Each superposed element-sheet was passed between a pair of juxtaposed 
pressure rollers. The superposed light-sensitive element was peeled away 
from the image-receiving layer one minute later, and the density of the 
dye transferred onto the image-receiving element side was then measured. 
Further, the superposing time was varied as given in the following table, 
and the transferred dye's densities were measured in the same manner. 
The following table shows the values obtained by measuring the reflection 
densities of the above dye images by a photoelectric densitometer through 
a red filter (.lambda. max 644 nm). In addition, as Samples H and J have 
no process control layers, the dye measurements were made after their 
peeled image-receiving elements were immersed in a buffer solution.

As apparent from the above table, it is understood that the light-sensitive 
element samples of the present invention, Samples G and H, require shorter 
periods of time to reach the maximum transfer image densities than do the 
comparative photographic light-sensitive element samples. Further, even 
when the process control layers are provided behind the cyan DRR 
compound-containing layer, the reduction of the transfer dye density is 
extremely small. 
EXAMPLE 4 
The following two different photographic elements were prepared by use of a 
positive image-formable dye-releasing C.P.M. comprising the cyan dye of 
the present invention, and a counter-part thereof for comparison, 
respectively. 
Sample for the Invention 
The following layers were coated in order over the layers (1) and (3) 
prepared in Example 2 provided on the 150.mu.-thick transparent 
polyethylene terephthalate film support, whereby Sample K was prepared. 
(1) Cyan dye-providable layer containing a negative-type silver halide 
emulsion (silver coating amount 1.08 g/m.sup.2), the foregoing positive 
image-formable dye releasing C.P.M. (Exemplified Compound (17)) (0.47 
g/m.sup.2), the following pyrazole-type electron donator (0.5 g/m.sup.2), 
N,N-diethyl-laurylamide (0.97 g/m.sup.2) and gelatin (1.94 g/m.sup.2). 
(2) Protective layer containing tetrakis(vinyl-sulfonylmethine)methane (0.2 
g/m.sup.2) and gelatin (2 g/m.sup.2). 
Comparative sample 
Sample L was prepared in the same manner as in the above with the exception 
that the positive image-formable cyan dye-releasing C.P.M. (Exemplified 
Compound 17) in the layer (1) of the above light-sensitive element of this 
example was replaced by the following Comparative Compound (3). 
Each of the above-prepared multilayered monochromatic light-sensitive 
elements was subjected to a given exposure through a silver step 
representing a wedge with each step density difference of 0.10. Each 
element was then superposed on the processing sheet prepared in Example 2, 
and a pod containing the same processing composition as used in Example 2 
was provided therebetween to prepare a film unit. The prepared film unit 
was passed between a pair of juxtaposed pressure rollers to thereby 
rupture the pod to spread the contents thereof into and between the 
light-sensitive element and the processing sheet. The changing densities 
to red light during 15 minutes immediate after the commencement of the 
development were measured continually at a temperature of 25.degree. C. 
Table 4 shows the time (t 0.5) required for the dye to reach the 50% and 
the time (t 0.8) to reach the 80% of the maximum density (Dmax). Dmax is 
obtained 15 minutes after the commencement of the development.

______________________________________ 
From the results shown in Table 4, it is understood that the positive 
image-formable dye-releasing compound comprising the cyan dye portion for 
the present invention is capable of giving a high density and has 
excellent speed as compared to the comparative compound having the same 
Car portion.
