Claim Text:
1. A dental resin modified glass-ionomer composition comprising the components: (a) an acidic polymer having a plurality of acidic functional groups selected from the group consisting of a carboxylic acid, a carboxylic acid anhydride, and a combination thereof, wherein the acidic polymer has a weight average molecular weight in a range of about 3,000 to about 100,000; (b) an acidic polymerizable monomer selected from the group consisting of 4-(meth)acryloxyalkyltrimellitic anhydride, 4-(meth)acryloxyalkyltrimellitic acid, and a combination thereof; (c) a non-acidic polymerizable monomer having at least one polymerizable group selected from the group consisting of an acrylate, a methacrylate, an acrylamido, a methacrylamido, and a vinyl group; (d) a fluoroaluminosilicate glass filler; (e) water; and (f) at least one polymerization initiator system selected from the group consisting of a photoinitiator system, a redox initiator system, an alkali aromatic sulfinate, and a combination thereof, wherein the ratio of (a):(b) is about 1:4 to about 4:1.
