Products of the reaction between isocyanates and hydroxyl compounds for textile finishing

摘要

A composition (CX), obtained by (a) reacting di- isocyanate(s) (component I) with 2-8C alcohol(s) and/or mono- and/or di-ethers thereof with at least two alcoholic hydroxyl groups and not more than two C-O-C linkages (component II) to give a product which still contains free isocyanate groups, (b) reacting with amine(s) containing two or more alcoholic OH groups to give another product which still contains free NCO groups (with the condition that at least one of the alcohols, ethers and amines used in (a) and (b) contains 3 or more alcoholic OH groups), (c) blocking the free NCO groups with a blocking agent and (d) possibly dispersing the product in water and adjusting the pH.
