Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A silver halide light-sensitive photographic material comprising a support having provided thereon, in order, a subbing layer and a silver halide emulsion layer, wherein said subbing layer contains a mixture of a binder and particles comprising a compound, in an amount of 70% or more, by weight of said particles, wherein said compound is a cyclic compound represented by Formula (I): ##STR12## wherein X and X' each represent --O--, --NH--, or --NR"--; R, R' and R" each represent a group comprising at least one element selected from the group consisting of H, B, C, N, O, F, P, S, and Cl; and n is an integer of 3 or more, provided that a+b=2, wherein a and b each represent a positive number.
Claim 2
