Pigments That Are At Least Partially Sheathed In Radiation-Curable Polyurethane, Their Production And Use

摘要

An aqueous dispersion comprises a pigment (B) at least partially enveloped by at least one radiation-curable polyurethane (A), at least one radiation-curable polyurethane (A) being obtainable by reaction of (a) at least one di- or polyisocyanate comprising on average from 1 to 10 allophanate groups and on average from 1 to 10 C-C double bonds per molecule, with (b) at least one further diisocyanate and with (c) at least one compound having at least two isocyanate-reactive groups.
