Abstract
Methods for covalently and indelibly anchoring a polyacrylate polymer using a UV-induced polymerization process in the presence of a photoinitiator to an oxide surface are disclosed herein. The methods and compositions prepared by the methods can be used as indelible marking materials for use on microelectronic packages and as solder and sealant barriers to prevent overspreading of liquids on the oxide surfaces of microelectronic packages. The polyacrylate polymers are covalently linked to the oxide surface by use during the printing and UV-curing process of an adhesion promoter having as a first domain an oxide-reactive silyl group, bonded via a linker to an acrylate-reactive group.
