Abstract

Coating compsns. comprise a 20-80 wt.% soln. in a solvent of a binder consisting of (A) 60-80 wt.% of an acrylic, with wt. average mol. wt. 6000-40000 (by GPC), having pendant aminoester gps. (I) of formula -COO-R-NH2 (where R=2-3C alkylene), or hydroxyamino ester gps. (II) of formula -COO-CH2-CH(NH2)CH2OH or -COO-CH2-CH(OH)CH2NH2; and (B) 20-40 wt. % of a glycidyl acrylic crosslinking polymer contg. at least 60 wt. % derived from a glycidyl monomer. The compsns. may contain pigments in a pigment:binder wt. ratio 1-200:100 (pref. 10-150:100): 0.1-4 wt. % of a catalyst (typically resorcinol, BF3.amine complex, or p-methoxy-phenol); and 0.1-5 wt.% of UV stabilizer (w.r.t. binder). (A) is prepd. by (i) soln. polymerisation of either methyl methacrylate (MMA) or styrene (S) with alkyl (meth)acrylates and (meth)acrylic acid, and reacting the polymer with alkyleneimine to form (I); or (ii) replacing the acidic monomer in the above by glycidyl methacrylate (GMA) and reacting the polymer with ammonia to produce (II). (B) is prepd. from G(M)A with 2-12C alkyl (meth)acrylates.
