Abstract:
A surface coating composition comprising a resin system and hydrophobic metal oxide particles having a median particle diameter of about 1-15 &mgr;m, wherein said composition, after application to a substrate, is characterized by (a) a moisture resistance equal to or greater than the moisture resistance of the same composition comprising hydrophilic metal oxide particles instead of hydrophobic metal oxide particles, which moisture resistance is retained for at least about 6 months, (b) a resistance to a 50% w/w ethanol/water solution that is equal to or greater than the resistance to a 50% w/w ethanol/water solution of the same composition comprising hydrophilic metal oxide particles instead of hydrophobic metal oxide particles, and (c) a gloss level of 50 gloss units or less.
