1. addition compound and salt thereof, it is characterized in that described addition compound can following by making (a) with (b1), (b2), (c1) and optionally (c2) reaction obtain:

  • (a) one or more per molecules have the polymeric polyisocyanate of at least two isocyanate group,(b1) compound of one or more formulas (Ia)Y-XH (Ia)Wherein,XH has reactive group to isocyanic ester, andY does not have reactive monomeric or polymer-based group to isocyanic ester, and described group does not comprise uncle'"'"'s amino, and contains one or more aliphatics, alicyclic and/or aromatic group,The compound of described general formula (Ia) has the mumber average molar mass M less than the 20000g/ mole n, and the compound of the formula of at least 55 moles of % (Ia) has the number-average molecular weight M of 150g/ mole~

    10000g/ mole n, and the functionalized polyoxyalkylene of its expression XH, based on the total amount of oxyalkylene units, the functionalized polyoxyalkylene of described XH comprises the oxyalkylene units with at least three carbon atoms of 40 moles of %~

    100 mole %, Supplementary condition are compound reactions of the isocyanate group and the formula (Ia) of 20%~

    90% composition (a),(b2) compound of one or more formulas (Ib)G-(XH) n (Ib) Wherein n is 2~

    4, and G is the aliphatics that comprises at least 2 carbon atoms, alicyclic and/or aromatic group, and it is amino and have and be no more than 3000 number-average molecular weight M that described group does not comprise uncle n, the reacting weight of described compound makes the isocyanic ester radical reaction of the described polymeric polyisocyanate of 0%~

    60% initial use, Supplementary condition are, as (b1) and (b2) result of reaction, the isocyanate group of the described polymeric polyisocyanate of 20%~

    90% initial use reacts altogether,(c1) compound of one or more general formulas (IIa)Z-Q (IIa)Wherein Q is-NH 2,-NHR or OH, wherein R is the alkyl with straight or branched of 1~

    18 carbon atom, and Z is the organic basic group that has at least one uncle'"'"'s amino and do not comprise isocyanate-reactive group,(c2) the optional compound of one or more general formulas (IIb)M-Q (IIb)Wherein Q is-NH 2,-NHR or OH, wherein R is the alkyl with straight or branched of 1~

    18 carbon atom, and M is the organic group that mumber average molar mass is no more than the 1000g/ mole, and it has amino and at least one hydroxyl of at least one uncle,Supplementary condition are isocyanate group and composition (c1) reactions of at least 10% composition (a).
