Total Claims: 14
Claim 1
Independent Claim
122 words
A process for manufacturing silver halide grains, which comprises the steps of: (A) providing a mixer vessel and a reactor vessel, said mixer vessel being separate from said reactor vessel and said reactor vessel having contained therein an aqueous protective colloid solution and in which silver halide grains are grown; (B) feeding an aqueous water-soluble silver salt solution, an aqueous water-soluble halide solution and an aqueous protective colloid solution into said mixer vessel; (C) forming a fine silver halide grain-containing solution by mixing the thus fed solutions in said mixer vessel; (D) immediately feeding the thus formed fine silver halide grain-containing solution into said reactor vessel; and (E) stirring said solution in said reactor vessel to grow uniform silver halide grains therein.
Claim 2
Dependent Claim
122 words
A process for manufacturing silver halide grains, which comprises the steps of: (A) providing a mixer vessel and a reactor vessel, said mixer vessel being separate from said reactor vessel and said reactor vessel having contained therein an aqueous protective colloid solution and in which silver halide grains are grown; (B) feeding an aqueous water-soluble silver salt solution, an aqueous water-soluble halide solution and an aqueous protective colloid solution into said mixer vessel; (C) forming a fine silver halide grain-containing solution by mixing the thus fed solutions in said mixer vessel; (D) immediately feeding the thus formed fine silver halide grain-containing solution into said reactor vessel; and (E) stirring said solution in said reactor vessel to grow uniform silver halide grains therein.
Claim 3
Dependent Claim
94 words
A process according to claim 1, wherein said silver salt solution, said halide solution and said protective colloid solution are present in said mixer vessel for a period of time as expressed by the following formula: ##EQU2## wherein t is the residence time of any one of said solutions in said mixer vessel; v is the volume of said mixer vessel (ml); a is the amount of said silver salt solution added (ml/min); b is the amount of said halide solution added (ml/min); and c is the amount of said protective colloid added (ml/min).
Claim 4
Dependent Claim

A process according to claim 2, wherein said residence time is 20 seconds or less.
Claim 8
Dependent Claim
26 words
A process according to claim 1, wherein said silver salt solution, said halide solution and said protective colloid solution are injected into said mixer vessel simultaneously.
Claim 9
Dependent Claim
18 words
A process according to claim 1, wherein said protective colloid solution is singly fed into said mixer vessel.
Claim 10
Dependent Claim
24 words
A process according to claim 1, wherein said protective colloid solution is mixed with said halide solution prior to feeding into said mixer vessel.
Claim 11
Dependent Claim

A process according to claim 8, wherein said protective colloid solution is added to said mixer vessel at a flow rate of at least 20% of the sum of the flow rates of said silver salt solution and said halide solution to said mixer vessel.
Claim 13
Dependent Claim
13 words
A process according to claim 1, wherein said protective colloid solution comprises gelatin.
Claim 14
Dependent Claim
