| 发明名称 | Dispersions of polyurethanes, their preparation and use | ||
| 摘要 | The present invention provides aqueous dispersions comprising a pigment (B) at least partially enveloped by polyurethane (A) and further comprising at least one polymerization inhibitor (C), said polyurethane (A) being obtainable by reaction of (a) 15% to 70% by weight of 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, and optionally(b) 0% to 60% by weight of further di- or polyisocyanate, with(c) 5% to 50% by weight of compound having at least two isocyanate-reactive groups, weight % ages being based on total polyurethane (A). | ||

| 主权项 | 1. An aqueous dispersion comprising a pigment (B) at least partially enveloped by a polyurethane (A) and further comprising at least one polymerization inhibitor (C), said polyurethane (A) having been obtained by the reaction of (a) 30% to 70% by weight of 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, and (b) 0% to 60% by weight of an additional di- or polyisocyanate, with (c) 30% to 50% by weight of a compound having at least two isocyanate-reactive groups, wherein the weight percentages are based on the total polyurethane (A). | ||
