A star-like or comb-like branched aliphatic polyamino compound useful for example in a curable resin composition is obtainable by a process comprising (a) forming an adduct of ammonia or an aliphatic amino compound having an amino group (compound A) with acrylate, (b) adding an alkylenediamine having 2 to 12 carbon atoms to be adduct to carry out an ester-amide exchange reaction, thereby obtaining a polyamino compound (B) having a total of 2 to 100 aliphatic primary amino and secondary amino groups per molecule and having a number average molecular weight of 170 to 10,000, and (c) forming an adduct of the polyamino compound (B) with an acrylic acid ester (C) of the formula (I), CH2=CHCOO-R1 wherein R1 is an alkyl group having from 4 to 50 carbon atoms or a group (CnH2n0)mR2 in which R2 is an alkyl group having from 1 to 5 carbon atoms, n is 1, 2 or 3 and m is from 1 to 25. |
