- 13. A process as claimed in claim 12 wherein said liquid crystal compound has the formula: ##STR64## and said member is selected from the group of: ##STR65##
- 14. A process as claimed in claim 13 wherein said liquid crystal compound has the formula: ##STR66##
- 15. A process as claimed in claim 13 wherein said liquid crystal compound has the formula: ##STR67##
- 16. A process as claimed in claim 13 wherein said liquid crystal compound has the formula: ##STR68##
- 17. A process as claimed in claim 13 wherein said liquid crystal compound has the formula: ##STR69##
- 18. A process as claimed in claim 13 wherein said liquid crystal compound has the formula: ##STR70##
- 19. A process as claimed in claim 13 wherein said liquid crystal compound has the formula: ##STR71##
