Abstract
The present invention relates to non aqueous, graftable coating composition comprised of a homogenous solution of a polymer and a spin casting organic solvent, where the composition does not contain acidic compounds, coloring particles, pigments or dyes, and the polymer has a linear polymer chain structure which is comprised of repeat units derived from monomers containing a single polymerizable olefinic carbon double bond, and the polymer contains at least one triarylmethyl chalcogenide containing moiety which is selected from the group consisting of repeat units having structure (I) an end chain group unit of structure (II) and mixtures thereof, and the polymer does not contain any repeat units or end groups containing water ionizable groups, ionic groups, free thiol groups, or free hydroxy groups, and where A1, A2, and A3 are independently an Aryl or a substituted Aryl; Y is a chalcogen selected from O, S, Se or Te; X1 and X2 are individually selected organic spacers; P1 is an organic polymer repeat unit moiety derived from a monomer containing a single polymerizable olefinic carbon double bound, and P2 is an end group moiety derived from a monomer containing a single polymeriza…
