These dyes which are unexpectedly non-photochromic produce red to blue shades on polyester fibers and exhibit one or more improved properties such as dyeability, dye exhaustion rate, light fastness, non-blooming, pH stability, build, fastness to ozone and nitrogen oxide, crock and wash fastness, migration, transfer, and pH stability on polyester and other fibers including cellulose ester.Type: GrantFiled: February 17, 1983Date of Patent: December 11, 1984Assignee: Eastman Kodak CompanyInventor: Max A.
