    Abstract: Epoxide-amine adducts (I) are claimed, contg. at least 20 wt% aliphatic epoxide and/or amine units with at least one tert. or quat. carbon atom. Also claimed are: (i) binders for coatings, contg. adduct(s) (I); (ii) mixts. of 0.1-99.9 wt% OH gp.-contg. copolymers and 99.9-0.1 wt% (I); (iii) binders for coatings, contg. mixts. (ii); (iv) coating materials contg. these binders, together with hardeners such as amino resins, capped or uncapped polyisocyanates and cpds. with acid and/or anhydride gps.. Pref. (I) are obtd.: (A) by reacting (a) 7-33C (cyclo)aliphatic mono-epoxides (a1), at least 20 wt% of which comprises monoepoxides with a tert. or quat. C atom with (b) 2-30C amines with at least 2 prim. or sec. amino gps. not attached directly to an aromatic ring; or (B) by reacting (a) 8-50C (cyclo)aliphatic diepoxides (a2) with (b) 4-30C prim. or sec. mono-amines with amino gps. not directly attached to aromatic rings, of which at least 20 wt% comprises mono-amines with at least one tert. or quat. C atom; or (C) by reacting (a1) with (b), the corresp. proportions of mono-amine and mono-epoxide with tert. or quat. C atoms being a% and b% respectively, where a + b = 20 and both a and b are greater than zero. The functionality of (I) is reduced by partial or complete reaction of the functional OH and amino gps., pref. by blocking with temporary protecting gps., esp. oxazolidine gps..
