Patterned roll for casting a patterned surface onto an opaque web

摘要

A patterned roll apparatus for casting a patterned surface onto an opaque web is disclosed.
The patterned roll comprises
a curing energy transparent cylinder (102) having an outer surface, the curing energy transparent cylinder (102) permitting at least 10 percent of curing light incident upon the cylinder to pass through the cylinder;
a tie layer (104) disposed on the outer surface of the curing energy transparent cylinder (102); and a plurality of curing energy opaque features (106,108) disposed on the tie layer (104) to form a pattern, the curing energy opaque features blocking at least 95 percent of curing light incident upon the curing energy opaque features.
