Varnish typically is comprised of some sort of resin and a solvent. (Turpentine, mineral spirits, etc.)
Actually you've hit it almost right on the head. I inadvertently used the term "driers" to mean
anything that aided drying, whether by evaporation or chemical / polymerization.
A varnish composition suitable for producing a liquid crystal aligning film
having a thickness of several tens to one hundred nanometers having 1 to
10% by weight of polyamic acid or soluble polyimide, and 90 to 99% by
weight of a solvent which comprises 5 to 80% by weight of at least one
compound selected from a group of solvent components A and 20 to 95% by
weight of at least one compound selected from a group consisting of
component B and component C where the group of solvent components A
consists of N-methyl-2-pyrrolidone and dimethylimidazolidinone and the
component B is alkyl lactate, and the component C is
R1-O(C3H.sub.6 O)nH (I)
where n is 1 or 2, R1 is an alkyl group having 4 carbon atoms when n
is 1, and R1 is an alkyl group having 1 to 4 carbon atoms when n is
2, is disclosed.
Thanks for helping clear that up. As I get older I seem to confuse myself by either thinking too much or not enough.........
