Appeal No. 2002-2217
Application 09/549,016
1. A resin obtainable from a compound of the formula 1
in which the substituents R2 and HNR1 can be in the ortho,
meta or para position relative to one another, and
R1 has the same meaning as R2, or has the meaning -COR2,
where R1 is independent of R2,
R2 is C1-C30-alkyl, C2-C30-alkenyl, C6-C18-aryl, C7-C30-alkyl-
aryl, by the steps, which can be carried out in
any order, of
A) reaction with an aldehyde of the formula 2
R3-CHO (2),
wherein R3 is H, C1-C30-alkyl, C2-C30-alkenyl, C6-C18-aryl
or C7-C30-alkylaryl, and
B) alkoxylation with a C2-C4-alkylene oxide in molar excess,
such that the resulting alkoxylate has a degree of
alkoxylation of from 1 to 100 alkylene oxide units per
-NH group,
and the resin has a molecular weight of from 250 to 100,000
units.
