Embedded lens retroreflective sheeting with flexible, dimensionally stable coating

摘要: A curable polymer composition for use in providing a dimensionally stable coating comprises semi-interpenetrating network. The network includes reactive component, cross-linking agent, and non-reactive component. component has molecular weight of about 7,000-30,000, preferably 15,000. In preferred embodiments, the 30,000-200,000, 40,000-60,000. Spacecoat compositions made with formulations described, exhibit good long-term stability, resistance to failure upon embossing substrate which retroreflective sheeting is applied.
