Primer for promoting adhesion of electroconductive metal oxide to plastic substrates

摘要

The present invention relates to primer for promoting adhesion of an electroconductive metal oxide coating over a plastic substrate, to a method of making such a primer, and to a method of adhering an electroconductive metal oxide coating to a plastic substrate. The primer is a carbonate diol-based crosslinked polyurethane, and is more particularly the reaction product of a carbonate diol, a low molecular weight polyol and methylene diisocyanate.
