This was considered the first industrial ready-to-use photographic paper print process. Aristotypes are composed of a paper layer, a layer of baryum sulphate in gelatin, and a layer of emulsion containing silver chloride suspended in a binder. The baryta layer made purer whites possible. As this was was a printing-out-paper, aristotypes are exclusively contact prints. ]]></termNote><termCreatedDate>2026-03-30 21:05:50</termCreatedDate><relation><relationType>UF</relationType><termId>31467374</termId><termName>aristotype</termName><termType>ND</termType></relation><relation><relationType>BT</relationType><termId>31452718</termId><termName>photographic prints by process</termName><termType>PT</termType></relation><relation><relationType>RT</relationType><termId>31340497</termId><termName>aristotype</termName><termType>PT</termType></relation><relation><relationType>RT</relationType><termId>31469813</termId><termName>aristo paper</termName><termType>PT</termType></relation></term>  </Zthes>
