PURPOSE:To suppress the increase of fogging caused by rapidly drying, and to improve the shelf-life stability of the tone in a silver image by incorporating a silver halide particle prepared in the presence of a spectrally sensitized color matter, and at least one kind of specified compds. in the title material. CONSTITUTION:The material contains the silver halide particle prepared in the presence of the spectrally sensitized color matter and at least one kind of the compd. shown by formula I. In formula I, A is a group shown by formula II wherein R<1> is hydrogen atom or a substd. or an unsubstd. 1-6 C alkyl group, R<2> and R<3> are each hydrogen atom or a substd. or an unsubstd. <=10 C alkyl, aryl or aralkyl group, L is a divalent binding group, (n) is or 1, (m) is 1 or 2. In formula I, B is a monomer unit copolymerized with a copolymerizable ethylenically unsatd. monomer, (a) is mol.% of said monomer contd. in the copolymer. Thus, the increase of the fogging caused by a sudden change in temperature and humidity is suppressed, and the tone of the silver image is stabilized. |
