摘要：
A silver halide emulsion, which is chemically sensitized by a compound of formula (1): wherein Ch represents a sulfur, selenium, or tellurium atom; X1 represents NR1 or N+(R2)R3Y−; R1 represents a hydrogen atom or a substituent; R2 and R3 each represent an alkyl group or another substituent; Y− represents an anionic ion; X2 represents OR4, N(R5)R6, or another substituent; R4 to R6 each represent a hydrogen atom or a substituent; and E is a group selected from groups represented by formula (2) to (5): wherein, in formulas (2) to (5), Z represents a hydrogen atom or a substituent; A1 and A2 each represent an oxygen atom, etc.; and R10 to R16 each represent a hydrogen atom or a substituent; W represents a substituent; n is an integer from 0 to 4; L represents a divalent linking group; and EWG represents an electron withdrawing group.
