Abstract
NEW MATERIAL:A 7-substituted-spiropyran derivative of formula I (R1 is H, lower alkyl, or phenyl; the formula II is benzene ring or maphtholene ring; the formula III is pyrrolidinyl, piperidino, or morphorino).
EXAMPLE: 7-pyrrolidinyl-spiro- [ 2H-1-benzopyran-2,3'- (3H) -naphtho (2,1-b) -pyran ] of formula IV.
USE: A coloring matter precursor for heat-sensitive recording, etc. (The coated surface of a recording chart is little colored and the recorded image is clean; furthermore, the color-developed coloring matter being hightly resistant to light, heat, and water.).
PROCESS: A pyrium salt of formula V (X- is an anion) and 2-hydroxy-4-substituted- benzaldehyde of formula VI are made to react in a volatile organic inert solvent to form a styryl compound of formula VII, which is then treated with a base.
