    摘要： A decal which is adapted to decorate bottles, containers and similar devices of the type having surfaces with high wetting angles is fabricated without the use of wax. The decal can be printed upon utilizing various inks to provide aesthetic container surfaces as for example utilized in the cosmetic industry. The decal is free of wax and consists of a carrier layer as a plastic or paper having impressed thereon a base and a release layer which typically is a suitable plastic type material. The plastic type material as secured to the base layer has imprinted thereon a suitable pattern employing an ink which can contain metallic pigments or other piggments. The printed pattern has deposited thereon an adhesive layer which is relatively thin and which layer is secured to a desired surface of the container at low temperatures. After securing the decal to the surface of the container the release and base layers are removed thereby leaving the printed matter on the surface of the container.

    摘要： A prepolymerization step prior to casting reduces shrinkage during polymerization of a composition containing diethylene glycol bis(allyl carbonate) with up to 40% of a vinyl ester, preferably vinyl acetate, and one or more free radical type initiators. The prepolymerization step includes adding a small amount of free radical type initiator, which may be the same or different than that used just prior to casting, and heating to a temperature higher than one hour half-lifetime temperature of the initiator. In this manner, most of the added initiator is consumed and the prepolymerization produces the highest possible conversion while preventing overpolymerization. High yield of lenses of ophthalmic quality is obtained.
