Abstract
A process for forming a coating on an uncured article which emits an olefinic monomeric vapor on curing and controlling the emission of said vapor into the atmosphere which comprises the steps of treating said uncured article with a top coating composition having at least one polymerizable olefinic compound and a polymerization catalyst, at least partially curing the coating composition so as to form a barrier film on the uncured article and then curing the uncured article.
Claims10
A photocured molding comprising a photocured resinous matrix, said matrix having emitted ethylenic monomer vapors during photocuring, a photocured top layer on said matrix which is formed from at least one olefinically unsaturated monomeric compound, and a polymeric barrier layer between said matrix and said top layer, said barrier layer being formed by said monomeric vapors and the olefinically unsaturated monomeric compound of which said top coat is formed.
