Abstract
Holding temperature, developing time, and agitation constant, the following relations exist: (1) In an elon-borax-sulfite developer, sulfite held constant and borax varied with the elon, γ = K log E + C, where E = elon conc. and K and C = constants: (2) In an elon-hydroquinone-borax-sulfite developer, hydroquinone and sulfite held constant and borax varied with the elon, γ = K log E + C, where E = elon conc. and K and C = constants: (3) In an elon-hydroquinone-borax-sulfite developer, elon, borax, and sulfite held constant, γ = K log H + C, where H = hydroquinone conc. and K and C = constants: (4) In an elon-hydroquinone-borax-sulfite developer, sulfite held constant and borax varied with the elon, γ = K1 log E + K2(log E)(log H) + K3 log H + K4, where E = elon conc., H = hydroquinone conc., and K1, K2, K3, K4 = constants: (5) In an elon-hydroquinone-borax-sulfite developer, γ and sulfite held constant, and borax varied with the elon, there exist optimum concentrations of elon and hydroquinone for maximum economy.
