Solid developer and its preparing process and usage

A solid developer is prepared from developer (naphethydiamine hydrochloride and sulfaniline amide or sulfanilic acid) and carrier (PVC) through dissolving the developer in solvent and volatilizing the solvent while uniformly attaching the developer on carrier. The mass ratio of naphethydiamine hydro...

Zusammenfassung:A solid developer is prepared from developer (naphethydiamine hydrochloride and sulfaniline amide or sulfanilic acid) and carrier (PVC) through dissolving the developer in solvent and volatilizing the solvent while uniformly attaching the developer on carrier. The mass ratio of naphethydiamine hydrochloride to sulfaniline amide is (0.1-3) : 10. The mass ratio of PVC to developer is (1-15) : 1. Its advantages are stable and quick developing (5 min).
