The paper is coated with a gelatin emulsion containing a silver bromide salt. The sensitivity of the paper allows photographers to make contact prints and enlargements from positives or negatives with artificial light. The prints may fade, yellow, or develop a dark iridescent appearance with age if not properly processed. ]]></termNote><termCreatedDate>2026-03-30 21:02:42</termCreatedDate><relation><relationType>UF</relationType><termId>31455845</termId><termName>paper, silver gelatin</termName><termType>ND</termType></relation><relation><relationType>UF</relationType><termId>31455846</termId><termName>silver gelatin papers</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31436860</termId><termName>photographic paper</termName><termType>PT</termType></relation></term>  </Zthes>
