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 .gamma. 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-contain…
