RETRORE-REFLECTIVE COATING MATERIAL WITH ABRASION RESISTANT CERAMER COATING

摘要

Retroreflective sheeting having an abrasion-resistant ceramer coating that is prepared from about 20% to about 80% ethylenically unsaturated monomers; about 10% to about 50% of acrylate functionalized colloidal silica; and about 5% to about 40% N,N-disubstituted acrylamide or N-substituted-N-vinyl-amide monomer having a molecular weight between 99 and 500 atomic mass units; wherein said percentages are weight percents of the total weight of said coating. A method of coating retroreflective sheeting with an abrasion-resistant cured ceramer layer is also disclosed.
