Abstract
A multi-branched compound which can give a compound having a relatively high molecular weight but a low viscosity and having excellent coating performances, and can give a solvent-less composition having sufficient coating performances and having a low viscosity sufficient for forming a coating, and which can serve to decrease the amount of a low-molecular-weight compound having performance problems and the multi-branched compound is obtained by reacting a core compound obtained by subjecting (a) a polyamino compound having a molecule containing a primary or secondary amino group and (b-1) an active-hydrogen-containing (meth)acrylic compound in Michael addition reaction with (c) a vinyl-group-containing compound having a functional group reactive with the active hydrogen.
