Abstract
A process in which a dye film is cast, the film is peeled off from the substrate and stretched monoaxially, the stretched film is applied to a glass film, and the resultant laminate is conditioned at elevated temperature gives composite materials which are highly suitable for the production of optoelectronic instruments.
Claims5
Laminate consisting of
- A. a glass film having a thickness of from 10 to 200 .mu., and
- B. a dichroic dye organic polymer film having a thickness of from 5 to 60 .mu.m whose extinction in linear-polarized light, measured on two superimposed films at the absorption maximum, is from 0.1 to 6.0 in the case of optical axes perpendicular to one another and from 0.03 to 0.2 in the case of parallel optical axes.
