发明名称 Ultraviolet curable resin compositions having enhanced shadow cure properties
摘要 This invention is of a resin composition including an additive of one or more organic peroxide thermal imitators to cationic photoinitiators, that are sensitized with alpha-hydroxy-ketones, which composition provides a self-propagating thermal curing reaction first activated by a short duration of surface ultraviolet radiation. The thermal reaction is non-directional, thus eliminating the line of sight limitation of current radiation curing processes. Complete curing can be achieved of the composition in a very short time; often after only a few minutes or less. The activation period can be provided by only a few seconds of ultraviolet light using a wide variety of commercial ultraviolet light sources.
