Accelerator Constituent Fresh Tank To process VISION Premier Color Print Film, the accelerator replenisher flow rate may need to be increased. If only a small amount of footage is processed no change in the flow rate should be required in the replenisher. For larger quantities of VISION Premier Color Print Film (more than one tank turnover), it is recommended to increase the flow rate by approximately 20% and closely monitor the PBA-1 level and retained silver in the D-max area of the film. Bleach Persulfate Bleach Only to be used in combination with accelerator solution.

Mix the accelerator only until all chemicals are dissolved. † The analytical method measures the total sulfite content of the solution and reports it as sodium metabisulfite (Na2S2O5). If a solution addition to the sodium metabisulfite level must be made but sodium bisulfite is to be used, multiply the sodium metabisulfite addition weight by the factor 1.09 to obtain the equivalent amount of sodium bisulfite. The difference between mix level and the analytical specification occurs because some sulfite is consumed in a reaction with KODAK Persulfate Bleach Accelerator PBA-1 to form the active accelerator species “in situ.” ‡ The analytical method measures buffer capacity and results are reported in terms of glacial acetic acid. Adjustment in pH should be made with glacial acetic acid or 50% sodium hydroxide. § For convenience, add PBA-1 from a 250 g/L stock solution. Prepare by dissolving 5 kg PBA-1 in water and diluting to 20 L. Each 4 mL of stock solution contains 1 g PBA-1. For a 100 L replenisher of AB-1bR, add 1.96 L of stock solution.

Hydrolysate, a soluble version of gelatin, is available from U.S. Gelatin Corporation. Both food and photographic-grade gelatin have been used successfully. The gelatin must first be dissolved in 40°C (104°F) water and stirred for 20 minutes. Up to 50 g/L can be added in this way in order to make a stock solution for subsequent use. Beta-aminopropionic acid is higher cost alternative offering easy solubility. † The analytical method measures the buffer capacity of the bleach and reports the result as mL/L of phosphoric acid (85%). The analytical specification (7.0 mL) is larger than the amount of phosphoric acid added (2.5 mL) because dihydrogen phosphate (and sulfate in seasoned solutions) also contributes to the measurement. If a correction must be made, phosphoric acid (85%) can be added on a mL-for-mL basis. For example, if the tank analysis reports 5.0 mL/L, then the correction would be to add 2.0 mL/L of phosphoric acid (85%). ‡ If the bleach tank overflow is being reused, the specific gravity (a measure of sulfate ion buildup) should not exceed this value as incomplete bleaching could occur. 9-22 Process ECP-2E Specifications
