Abstract

PURPOSE:To munufacture the titled emulsion capable of giving a high quality dot image even by lith development for a time longer than standard developing time by adding rhodium salt, cyanine dye and polyalkylene oxide compound at specified times in a process of manufacturing a silver halide photographic emulsion. CONSTITUTION:In a process of manufacturing a silver halide emulsion in which >=70mol% of the total silver halide is silver chsporide, rhodium salt or iridium salt is added by 10<-9>-10<-5>mol per one mole of silver halide before finishing primary aging, and after desalting to the emulsion are added cyanine dye represented by formula I or II [where each of R<1> and R<2> is alkyl or carboxyalkyl having sulfo; each of X<1> and X<2> is H, alkyl, alkoxy, hydroxy or alkoxycarbonyl; each of R<3> and R<4> is a substituent other than H, halogen and aryl; L is a group of formula III or IV (R<7> is H or 1-3C alkyl); M is a cation; each of X<3> and R<5> is H, halogen, aryl or the like; and R<6> is H or alkyl] and polyalkylene oxide compound by <=2X10<-4> mol per mol of silver.
