    Abstract: Amino-urethanes (I) claimed are of formula R3-N(Re)-A-R1-NH-C(O)-O-CH2-CH(OH)-CH2- R-CH2-CH(OH)-CH2-O-C(O)-NH- R1-A-N(R2)R3 R is residue of a diglycidyl ether or ester, or 2-18 alkylene gp.; R1 is opt. branched 2-18C alkylene; R2 is H, 1-8Calkyl, or 1-8C hydroxyalkyl; R3 is R2, or R3 with R2 can form cyclic ring, or, if R2 is H then R3 can be at least one gp. of formula (a) -C(O)-O-CH2-CH(R4)-CH2- (R-CH2-CH(R4)-CH2-OmB-(R4)n R4 is OH or -CONH-PI-NHCO R6; B is residue of a polyol; m is 1-3; n is 1-6; and PI is residue of a polyisocyanate and R6 is residue of (cylco)aliphatic, or alkylaromatic alcohol, an aminoalcohol, ketoxime, or a CH- or NH- acidic cpd.: b) R3 is gp. of formula (I) R5 is H or R4; R7 is 1-8Calkyl; and s is 1-6; c) -C(O)-NH-PI-NH-C(O)-O-B-d)R8-CHOH-CH2-O-CO-; e) R8-CHOH-CH2-; R8 is H, 1-18C alkyl, or residue of a glycidyl ester or ether; or f) PI'NHCO- PI' is residue of a partly capped polyisocyanate; and A 75 chemical bond or -R1NH)r-R1NH- r is 0-6. Prodn. of a (I) by heating an at least bifunctional 2-oxo-1,3-dioxolan (II) and a prim polyamine at 20-150 deg.C is claimed. Structural formulae are given for pref. R, viz. residues of a bisphenol diglycidyl ether opt. linked by residues of a diamine, diol, dicarboxylic acid, di-isocyanate, etc. Pref. (II) is bicyclic carbonate of specified formuls esp. derived from polyglycidyl ether of a polyphenol, or a epoxide-cyclic carbonate.

    Abstract: An article of manufacture comprising a substrate which is coated with a primer and a second coating adhering to the primer. The primer comprising as an essential ingredient an epoxy resin modified by acetoacetic ester groups which may also contain chemically bound metal atoms as a chelate. The cover layer contains a homo- or a copolymer of a fluorine-containing vinyl monomer having up to two fluorine atoms or a combination of such polymers.
