Abstract
A polymerization initiator composition controlling polymerization at interface, comprising a (thio)barbituric acid compound represented by the general formula I: ##STR1## wherein R.sup.1 is an alkyl group of 1 to 3 carbon atoms, R.sup.2 and R.sup.3 are independently hydrogen atom or an alkyl group of 1 to 3 carbon atoms, and X is oxygen atom or sulfur atom, and (a) a metal halide represented by the general formula, MY.sub.n wherein M is Cu or Fe, Y is halogen atom, and n is an integer of 2 when M is Cu or an integer of 3 when M is Fe, or (b) a halogen ion-forming compound and M.sup.m -forming compound wherein M is Cu or Fe and m is 2+ when M is Cu or 3+ when M is Fe, and a curable composition comprising the (thio)barbituric acid and radically polymerizable monomer.
