(2) latex polymer B having a Young's modulus ranging from about 10 MPa to about 6 GPa, and a strain, under stress at 0.5 MPa, of less than about 5%, wherein latex polymer B is Acrylates copolymer, Polyacrylate-2 crosspolymer, Styrene/Acrylic copolymer, Polyurethane-35, Polyurethane-1, Polycarbamyl Polyglycol Ester, Styrene/Acrylates Copolymer, or Styrene/Acrylates/Ammonium Methacrylate Copolymer;
wherein latex polymers A and B are dispersed particles in an aqueous dispersion medium;

(b) a dispersion of particles of at least one silicone latex polymer, wherein the silicone latex polymer is formed from (i) dimethylvinylsiloxypolydimethylsiloxane and (ii) organohydropolysiloxane of formula (II):

 wherein n ranges from 15 to 25;
and optionally,
(c) a solvent;
