? The object of the present invention is to provides a novel polyhalogenomethylsulfonyl compound which can be used for providing a thermally processed image recording material which has a high sensitivity, gives less fog, and has a good stock stability and a good image storage stability of dark and high temperature or light storage. According to the present invention, there is provided a polyhalogenomethylsulfonyl compound represented by the following formula (1), or salts thereof, or hydrates or solvates thereof:
1
wherein Z
1
and Z
2
each independently represents a halogen atom; A represents a hydrogen atom or a halogen atom; and R
1
represents an alkyl group having from 2 to 12 carbon atoms, which may have one or more substituents, an alkenyl group having from 2 to 12 carbon atoms, which may have one or more substituents, or an alkinyl group having from 2 to 12 carbon atoms, which may have one or more substituents.
本发明的目的是提供一种新型的聚卤代甲基磺酰化合物,可用于提供具有高灵敏度、较少雾化、良好的库存稳定性和良好的暗高温或光存储稳定性的热处理图像记录材料。根据本发明,提供了由以下式(1)表示的聚卤代甲基磺酰化合物,或其盐,或其水合物或溶剂化物:其中Z1和Z2各自独立地表示卤素原子;A表示氢原子或卤素原子;R1表示具有2至12个碳原子的烷基基团,可以具有一个或多个取代基,具有2至12个碳原子的烯基基团,可以具有一个或多个取代基,或具有2至12个碳原子的炔基基团,可以具有一个或多个取代基。
