PURPOSE:To improve a change of sensitivity due to natural storage by incorporating at least one kind of methine dye. CONSTITUTION:At least one kind of methine dye represented by formula I is incorporated. In the formula I, MET is a group of atoms having the structure of a methine dye, Q is a divalent combining group consisting of atomic groups or atoms including at least one among C, N, S and O, Ar is a group having an arom. polycyclic compd. consisting of >=8 atoms other than N, l1 is 1 or 2, l2 is 0 or 1 and l3 is 1, 2, 3 or 4. High sensitivity is ensured, fog increases hardly during storage at high temp. and/or high humidity and a change of the sensitivity is reduced.
