Dye destruction
From Wikipedia, the free encyclopedia
Dye destruction is a photographic printing process, in which dyes embedded in the paper are bleached (destroyed) in processing. Because the dyes are fully-formed in the paper prior to processing, they may be formulated with few constraints, compared with the complex dye couplers that must react in chromogenic processing. This has allowed the use of richly colored, highly stable dyes. Ilfochrome, currently the only widely-available dye destruction process, is known for its intense colors and archival qualities.
