Sounds like the description of Gum dichromate to me, maybe this is a synonym? --Rxke 19:50, 16 August 2005 (UTC)[reply]

Very similar...but gum dichromate uses gum tragacanth or one of a number of similar gums derived from acacia sap. Sun printing uses a different reaction with gelatine which provides a more robust tanned protein image from which the final prints are made. Velela 22:04, 16 August 2005 (UTC)[reply]

Light-sensitive vat dyes: Inkodye is a specific product name[edit]

The section reads a bit like an ad for Lumi Inkodye. There are many other heliographic dyes out there besides Inkodye. Can this section be re-written to be more neutral? — Preceding unsigned comment added by Freshmangomango (talk • contribs) 19:21, 18 July 2012 (UTC)[reply]
