Abstract: The invention relates to a tackifier dispersion comprising a resinous material and an emulsifier, the emulsifier being obtainable by a method comprising providing an ester of one or more fatty acids containing at least two conjugated double bonds, reacting the ester with a dienophile containing an acid or anhydride group, to form an intermediate product A, and, reacting the intermediate product A with one or more polyalkylene glycols. The invention also relates to a method for the production of a tackifier dispersion, its use as a tackifier, and an adhesive composition comprising the tackifier dispersion. The invention further relates to an emulsifier, a method of producing the same and its use for emulsifying resinous materials.

Abstract: The present invention relates to a method to prepare dimerized rosins dispersible in water in presence of extremely low level of dimerization acid catalyst. The present invention relates also to its use as a tackifier resin, solid or in water, and ink resin, and an adhesive composition and ink composition comprising the rosin resin.
