Definitions
- the invention relates to a method of image formation using a thermal recording material or heat developable light-sensitive material.
- thermal recording materials have advantages, such as easy operation and maintenance, feasibility for reduction in equipment size and cost and low running cost.
- thermal transfer printing has recently been the subject of many research and development activities as can satisfy the requirements for both image quality and cost, in which a thermal transfer ribbon, comprising a support and a layer of dispersion of dye or pigment in binder coated thereon, and recording paper are superposed and heat according to the image information is applied to the back face of the thermal transfer ribbon via a thermal head to record images.
- the thermal imaging method using a laser beam has also recently been investigated, which is described in an special issue "Imaging Part 2, - Current Hard Copy Printer Technology" of "Shashin Kogyo", pp. 63-113 (published by Shashin Kogyo Shuppansha on July 20, 1988), for instance.
- silver halide photographic light-sensitive materials have a handling problem of the necessity for use of liquids such as a developer, though they surpass other image recording materials with respect to image quality.
- the heat development method As a means of solving this problem, what is called the heat development method has been developed, in which exposure is followed by heat development to form images. Details of such a heat development method are given in the proceedings of the 17th symposium of the Society of Photographic Science and Technology of Japan titled “Discussion on Heat Developable Silver Salt Recording System” (May 1987). .
- silver or dye images are formed by heat treatment and, if necessary, pressure treatment, after imagewise exposure of a heat developable light-sensitive material having a light-sensitive silver halide, a binder and a reducing agent on the support.
- heat developable light-sensitive materials offer high image quality similarly to silver halide light-sensitive materials, the image quality level is lower than that obtained with conventional liquid processable light-sensitive materials. With this background, further improvements are desired, and development of positive-type heat developable light-sensitive materials is desired.
- 1,3-sulfur-nitrogen-containing compounds are known to undergo cleavage reaction by the action of silver ion. Attempts have been made to utilize this reaction for imagewise release of reagents in photographic processing.
- Japanese Patent Examined Publication No. 7576/1980 describes a technology in which a 1,3-sulfur-nitrogen-containing compound is cleaved according to the imagewise distribution of silver ion to release a photographically useful group (hereinafter referred to as PUG), with mention of its applicability to so-called instant photographic materials.
- photographically useful groups include image forming dyes, their intermediates, antifogging agents and gelatin hardeners.
- silver ions are supplied in the form of a soluble silver complex ions by the action of a silver halide solvent. An imagewise distribution of silver ions occurs in the unexposed portion.
- Japanese Patent O.P.I. Publication No. 180548/1984 discloses a method by which a mobile dye is imagewise formed by heating a 1,3-sulfur-nitrogen-containing compound as a dye donator for heat developing type light-sensitive material preferably in the presence of base.
- the heat developing type light-sensitive material containing a base or base precursor has a drawback of tendency toward maximum density reduction, though it permits fogging reduction in the desired dye image by acceleration of silver development.
- Particularly recording materials incorporating a hydrophilic binder are normally used after being subjected to aging at a given temperature for a given period to increase the degree of hardening.
- This aging is carried out at temperatures of normally 25 to 50°C, preferably 30 to 45°C for periods of normally 12 hours to 1 month, preferably 1 day to 2 weeks.
- a mobile dye forming reaction can take place even during this storage for improvement in the degree of hardening, which leads to a considerable tendency toward image quality deterioration such as increased fogging.
- the present inventors found that reaction takes place between an organic silver salt and a 1,3-sulfur-nitrogen-containing compound in the presence of a thermal solvent, and substantially in the absence of water and base, and that the use of this reaction makes it possible to obtain a recording material accomplishing the objects described above.
