US 6,187,897 B1 · Vinyl-group-containing dendrimer and curable composition

Abstract

A vinyl-group-containing dendrimer useful in coating and printing and is curable by any one of conventional triggers such as heating, ultraviolet light, infrared light, electron beams and γ rays, the composition comprising a vinyl-group-containing dendrimer (A) comprising a core portion, branching portions, branches and at least 4 terminal portions and having a vinyl group as a terminal portion and a long-chain group and a curable unsaturated-group-containing compound (B), and the composition comprising a vinyl-group-containing dendrimer (A) obtained by reacting a polyfunctional compound (a) having at least three active-hydrogen-containing groups in a terminal per molecule and having at least five active hydrogen atoms per molecule with a long-chain-group-containing compound (b) having a functional group reactive with an active hydrogen atom so as to leave part of the active hydrogen atoms, thereby obtaining a long-chain-group-containing multi-branched compound (X), and reacting the long-chain-containing multi-branched compound (X) with a vinyl-group-containing compound (c) having a functional group reactive with an active hydrogen atom and a curable unsaturated-group-containing compound (B).
