Claims32
A composition comprising:
- (i) 10 to 80 wt.-% organic binder;
- (ii) 0.01 to 5 wt.-% polymerization initiator;
- (iii) 20 to 90 wt.-% particulate composite filler, comprising a polymerized mixture of organic binder and inorganic filler, the composite filler particles having an average particle size of 20 to 50 μm, each wt-% of (i), (ii), and (iii) relative to the total mass of the composition;
- and
- wherein the composition contains at most 10 wt.-% composite filler particles having a size of <10 μm, relative to the total mass of the particulate composite filler in the composition.
