Claims
- 1. A method for forming a high-contrast negative image which comprises developing an exposed negative type silver halide photographic light-sensitive material with a developer in the presence of a hydrazine derivative wherein said developer contains at least (1) 0.1-0.8 mol/l a developing agent, (2) 20-60 g/l of a hydroquinonemonosulfonate, (3) 0.3 mol/l or more of a sulfite and (4) an amino compound which in the presence of said hydrazine derivative, accelerates enhancement of contrast said amino compound being present in an amount of 0.005-1.0 mol/l and has a pH of 10.5-12.3.
- 2. A method according to claim 1, wherein the hydroquinonemonosulfonate is hydroquinonemonosulfonic acid and/or a salt thereof.
- 3. A method according to claim 1, wherein the developing agent (1) is a dihydroxybenzene developing agent or a combination of a dihydroxybenzene developing agent with a 3-pyrazolidone developing agent and/or a p-aminophenol developing agent.
- 4. A method according to claim 1, wherein the hydrazine derivative is contained in the developer or the light-sensitive material.
- 5. The method of claim 1 wherein the amino compound is an amino alcohol.
- 6. The method of claim 5 wherein the amino alcohol is present in an amount of 0.005-1.0 mol/l.
