ABSTRACT:
A macromolecular azo compound is produced by the reaction of a compound having at least 1 diazo linkage and at least 2 hydroxyl groups in a molecule, a compound having at least 2 isocyanate groups in a molecule and a compound having at least 2 hydroxyl groups in a molecule. A resin useful as a paint can be obtained by polymerizing a polymerizable unsaturated bond-containing monomer in the presence of this compound.
