The brand name is no longer around.What was the name for latex paint in the late 50's to mid 60's. Perhaps it was a brand name.?
Latex paint is a Canadian invention. (Swell with patriotic pride!) CIL invented it in the 1940's. It uses a resin from the rubber tree called ';latex'; as the binder. The advantage is latex paint can be reduced with water and doesn't smell bad.
