US 3,107,170: Netke, Production of color images in sensitive emulsions
In my opinion it's very significant since it seems to point to a direction similar to that taken by Denisyuk's approach to Lippmann.
US 4,054,453: Grobin, Lippmann film with reflective layer
Less toxic metals like gallium are proposed to form a reflector.
