THERMALLY DEVELOPABLE MATERIAL AND IMAGE FORMING METHOD USING SAME

摘要

PROBLEM TO BE SOLVED: To provide thermally developable compositions which include color toning agents, have excellent image density, shorten development time, and can be developed at lower processing temperatures. SOLUTION: The thermally developable compositions include non-photosensitive sources of reducible silver ions and triazine-thione compounds represented by structural formula (I), wherein R1-R5each independently represents a substituent bonded to the triazine-thione ring through a single bond.
