Abstract:
A composition comprising:(a) an aqueous dispersion of particles of at least one film-forming polymer containing at least one acidic function, said acidic function being in free or partially neutralized form, wherein said at least one film-forming polymer is a polymer containing a sulphonic acid or sulphonate function obtained by the copolymerization of at least one sulphonic acid or sulphonate group with at least one monomer selected from:(i) linear, branched, or cyclic vinyl esters;(ii) linear, branched, or cyclic (meth)acrylic acid esters;(iii) mono- or di-substituted linear, branched, or cyclic (meth)acrylic acid acrylamides; and(iv) styrene, .alpha.- methylstyrene or a substituted styrene, and(b) at least one pigment dispersed in the aqueous dispersion, wherein the pigment is not formed by oxidative polymerization of an indole compound, wherein the composition is a temporary hair dye for animal or human hair.
