Claims
- 1. A method of manufacturing a covered solid processing agent for a silver halide photographic light-sensitive material, the method comprising the step of:
- forming granules;
- molding the granules into a tablet to form a solid processing agent;
- dissolving or dispersing in a solvent an additive selected from the group consisting of a sulfite and a compound represented by the following Formula (1), (3) or (4): ##STR14## wherein R.sub.11 and R.sub.12 independently represent a hydrogen atom or a substituted or unsubstituted alkyl group, provided that R.sub.11 and R.sub.12 may be the same or different or R.sub.11 and R.sub.12 may combine with each other to form a ring, ##STR15## wherein X represents an alkyl group or --OH; n represents an integer of 0 to 3; provided that when n is 2 or more, X may be the same or different; Y represents --COOM or --SO.sub.3 M wherein M represents a hydrogen atom, an alkali metal or --NH.sub.4 ; and m represents an integer of 1 to 3, provided that when m is 2 or more, Y may be the same or different;
- A--COOM Formula (4)
- wherein A represents a substituted alkyl or alkenyl group, in which the substituent is --OH or --COOM; and M represents a hydrogen atom, an alkali metal or --NH.sub.4 ; and
- spray coating the surface of the solid processing agent in the form of the tablet with the resulting solution or dispersion to cover at least a portion of the surface of the tablet solid processing agent with the additive, wherein the weight content of the additive is 0.05 to 5% by weight of the agent.
- 2. The method of claim 1, wherein the weight content of the additive is 0.1 to 1 per l of the total amount of the additive and the covering agent.
- 3. The method of claim 1, wherein the compound represented by Formula (1) is a compound represented by the following Formula (2): ##STR16## wherein R.sub.21 represents a hydrogen atom or an alkyl group; L.sub.21 represents an alkylene group; and A.sub.21 represents a carboxyl, sulfo, phosphono, phosphinic acid, hydroxy, amino, ammonio, carbamoyl or sulfamoyl group or R.sub.21 and L.sub.21 combine with each other to form a ring.
- 4. The method of claim 1, wherein the solid processing agent is in the form of a specific geometrical tablet.
- 5. The method of claim 1, further dissolving or dispersing in said solvent a covering agent selected from the group consisting of a water-soluble polymer and a saccharide.
- 6. The method of claim 1, wherein said at least a portion of the surface of the solid processing agent is not less than 1/2 of the surface area of the agent.
- 7. The method of claim 1, wherein said at least a portion of the surface of the solid processing agent is not less than 70% of the surface area of the agent.
- 8. The method of claim 1, wherein said at least a portion of the surface of the solid processing agent is the entire surface of the agent.
