Abstract

PURPOSE:To prevent the formation of a mixed crystal in a boundary region having different halogen compsns. when laminate type silver halide particles are formed, by changing the silver halide compsn. in the presence of at least one kind of compd. selected among a heterocyclic mercapto compd., an azaindene compd. and a spectral sensitizing dye. CONSTITUTION:When laminate type silver halide particles are formed, the silver halide compsn. is changed in the presence of at least one kind of compd. selected among a heterocyclic mercapto compd., an azaindene compd. and a spectral sensitizing dye. The laminate type silver halide particles are formed by producing silver halide particles and growing the particles until the desired laminate type silver halide particles are obtd. Any compd. having at least one mercapto group and at least one hetero ring may be used as the heterocyclic mercapto compd. A tetrazaindene compd. is preferably used as the azaindene compd. Thus, the formation of a mixed crystal in each boundary region having different halogen compsns. is prevented.
