主权项

1. A composition, comprising, in a physiologically acceptable medium:
a) a siloxane resin comprising at least 80 mol % of units
(i) at least one M unit of formula (R′3SiO1/2)a, and(ii) at least one Q unit of formula (SiO4/2)b, wherein R′ independently represents an alkyl group comprising from 1 to 8 carbon atoms, an aryl group, a carbinol group, or an amino group, with the condition that at least 95 mol % of the R′ groups are alkyl groups, wherein a and b are values greater than 0, and wherein a ratio a/b is between 0.5 and 1.5; b) a film-forming propyl silsesquioxane resin comprising at least 80 mol % of at least one T unit of formula R″SiO3/2, wherein R″ independently represents an alkyl group comprising from 1 to 8 carbon atoms, an aryl group, a carbinol group, or an amino group, with the condition that at least 40 mol % of the R″ groups are propyl groups, wherein a weight ratio between the resins a) and b) is between 1/99 and 99/1, wherein the resins a) and b) are not bonded to one another via covalent bonds, and wherein a number of M units in the final mixture is less than a number of T+Q units; c) a mineral filler that is talc; and d) an organic filler that is polymethyl methacrylate (PMMA).
