The invention relates to a photosensitive adhesive composition of the polymerisable resin type, the hardening of which occurs by means of polymerisation and/or reticulation, characterised in comprising:—initiating means for at least one chain polymerisation reaction to guarantee the hardening of said composition and a sufficient quantity of at least one bifunctional monomer, comprising a photolabile centre with at least one photolabile entity and at least two polymerisable units, connected by covalent skeletons to said photolabile centre and located away from the cleavage sites of said photolabile centre, such that said composition loses the integrity and adhesivity thereof under the influence of a reticulating radiation causing the cleavage of the photolabile sites. The composition is particularly of application in dentistry.
本发明涉及一种可聚合树脂类型的光敏粘合剂组合物,其硬化是通过聚合和/或网状反应实现的,其特征包括-至少一个链式聚合反应的引发装置,以保证所述组合物的硬化,以及足够数量的至少一种双功能单体,该单体包括一个具有至少一个光敏实体的光敏中心和至少两个可聚合单元,通过共价骨架与所述光敏中心连接,并远离所述光敏中心的裂解位点,从而使所述组合物在网状辐射的影响下失去其完整性和粘合性,网状辐射会导致光敏位点的裂解。这种成分尤其适用于牙科。
