Abstract
NEW MATERIAL:Imidazothiazine compounds of formula I (wherein R1 is H, methyl, methoxy; R2, R3 are lower alkyl or together form five-membered or six- membered heterocyclic ring in formula II; R4 is H or residue of a quaternizing agent; n is 1, 2 or 3; A is an anionic group).
EXAMPLE: The compound of formula III.
USE: Cationic dyes which dye polyacrylonitrile fibers to vivid greenish yellowWyellow.
PREPARATION: A heterocyclic compd. of formula IV (wherein R1, R2, R3, n have the meaning set forth above) is reacted with a quaternizing agent or an acidic compd. capable of forming a salt to produce an imidazothiazine compd. of formula I. Example of the quaternizing agents are methyl iodide and benzoyl chloride. Examples of the acidic compd. are hydrochloric acid, benzenesulfonic acid, and monochloroacetic acid.
