載されている。There are various types of heat-developable color light-sensitive materials. For example, a method in which a diffusible dye is released or formed by thermal development and then the dye is transferred to obtain a color image (hereinafter referred to as a transfer method). Requires an image receiving member for transfer, but is excellent in terms of image stability, sharpness, simplicity and speed of processing, and the like. The heat-developable color photosensitive material of this transfer system and the image forming system are described in, for example, JP-A-50-12431, JP-A-59-159159, JP-A-59-181345,

感光性層及び／または非感光性層に添加されている。In a photothermographic material, a thermal solvent is often added to the photothermographic material for the purpose of activating thermal development. In particular, a diffusive transfer type photothermographic material increases the efficiency of forming a diffusible dye. Various thermal solvents or solvents are added to the photosensitive layer and / or the non-photosensitive layer of the photothermographic material for the purpose of improving the transfer efficiency of the dye.

多い。Conventionally known thermal solvents are in a liquid state at around room temperature and in a solid state at around room temperature. However, they are liquefied at the time of heating and developing to exhibit various functions of the thermal solvent. Examples of the former include alcohols, polyols, phenols and relatively low molecular weight ureas,
Many typical amides can be found in amides, etc. However, this kind of thermal solvent which is liquid at normal temperature is often hygroscopic by itself or liquid in photosensitive material. In many cases, the light-sensitive material is sticky or sticks to the back surface of the light-sensitive material or other substances, which makes it difficult to put into practical use.

There are compounds described in -198528.
ところでかかる固体熱溶剤は、上記したベタつきやく
っつきの物理的性能以外にも種々の物理的性能面で欠点
のないことが要求される。例えば、 （１） 熱溶剤が、感光材料の保存中や、加熱現像時に
揮散（昇華或いは気化）しない。By the way, such a solid thermal solvent is required to be free from defects in various physical performances in addition to the physical properties of stickiness and sticking. For example: (1) The thermal solvent does not volatilize (sublimate or vaporize) during storage of the photosensitive material or during heat development.
（２） 感光材料の製造時に固体微粒子状として分散状
態にある時に安定である。(2) It is stable when it is in a dispersed state as solid fine particles during the production of a photosensitive material.
（３） 感光材料の保存時に安定した固体微粒子状態で
存在し、粗大化を起さない。(3) The photosensitive material is present in a stable solid fine particle state when stored, and does not cause coarsening.
（４） バインダーの硬膜に悪影響を起さない。(4) Does not adversely affect the hardening of the binder.
等の物理的性能が要求される。勿論こうした物理的性能
以外に、本来の熱溶剤性、即ち、熱現像時の現像の活性
化及び拡散性色素の転写効率の増大が要求されるのは言
うまでもない。Physical performance is required. Of course, in addition to such physical performance, it is needless to say that thermal solvent properties, that is, activation of development during thermal development and an increase in transfer efficiency of the diffusible dye are required.
しかしながら、従来から知られている熱溶剤は、かか
る見地から見た場合、いずれの性能も充分満足し得るも
のはなく、こうした物理的欠点のより少ない熱溶剤が要
求されている。However, none of the conventionally known thermal solvents can sufficiently satisfy any of the performances from such a viewpoint, and a thermal solvent having less physical defects is required.
従って、本発明の目的は、上記物理的欠点のない、優

General formula (I) In the formula, R 1 represents an alkyl group, and R 2 represents an alkyl group, an alkenyl group, or an aryl group. The above groups represented by R 1 and R 2 include those having a substituent. R 3 represents an alkylene group. R 4 represents an alkyl group, an aryl group, an alkoxy group, an aryloxy group (each of the above groups includes those having a substituent), a halogen atom, or CONHR 5 (R 5 represents an alkyl group or a hydrogen atom). k is 0 or 1, l
