3 Terms and Definitions

The following terms and definitions apply to this document.

3.1

liquid medicine bath

Aqueous solutions of chemicals used in wet processing.

3.2

bleaching

In the black-and-white inversion step, the image silver formed by reduction is converted to soluble silver sulfate salts, and the subsequent (reversal or negative) color

Cleared during processing.

NOTE. This step converts reduced silver in the image to soluble silver sulfate salts, which are removed by fixing and washing with water.

3.3

bleaching

fixing

The bleaching and fixing steps are combined in a single solution.

NOTE. This is a step of color processing.

3.4

cleaning

The liquid medicine uses black and white inversion treatment to wash away the soluble silver sulfate and pollutants formed by the bleaching reaction.

NOTE. This is the step to remove the contaminants produced during the bleaching process.

3.5

Coupler coupler

A compound that combines with the oxidation product of the developer during color development to form a dye.

Examples. phenols, naphthols, pyrazolones
