Title:
DYESTUFF FOR PERFLUOROPOLYOXYALKYLENE AND COMPOSITION BASED ON PERFLUOROPOLYOXYALKYLENE CONTAINING THE DYESTUFF
Document Type and Number:
Japanese Patent JP3555768
Kind Code:
B2
Abstract:
PURPOSE: To enable a dyestuff to be dissolved in a polyfluoropolyoxyalkylene by reacting a specific dyestuff with a compound having a perfluoropolyoxyalkylene structure.
CONSTITUTION: This dyestuff for polyfluoropolyoxyalkylenes of formulae III, IV [wherein, Q is an organic group not containing free or an alkali metal- salified sulfonic(amide) and/or a carboxylic group but containing a chromophore group; A is a chain having a perfluoroalkylene structure and consists of perfluoroxyalkylene units of formulae V-XI (wherein, X is F or CF3), formula X (wherein, Z is from 1 to 3; (m), (n) and (p) are each from 0 to 50, the sum of them are 2 or more; (k) is 1 in the case of a dyestuff of formula III and is 0 in the case of a dyestuff of formula IV), and the average molecule weight of the chain is 500-15000; B is a bivalent organic group; (t) is 1 or 2 and (s) is 1 or 2] is obtained by reacting the dyestuff of formula I and the compound having perfluoropolyoxyalkylene structure of formula II.
