Claims
- 1. A resin composition for coating comprising a urethane-modified epoxy-polyamine resin (g) obtained by first reacting a diepoxide compound (a) selected from the group consisting of the compounds represented by the following general formulae (I) and (II) whereinR1 represents a hydrogen atom or an alkyl group of 1-6 carbon atoms, m and n are respectively a number of 0 or more, and the sum of m and n is in the range of 1-20, x is an integer of 1-9, and y is a number of 1-50, and a bisphenol A epoxy resin of an epoxy equivalent 170-500 with a bisphenol (b), reacting the epoxy resin (c) thus obtained with a cyclic ester (d) represented by the following general formula (III) whereinR2 represents a hydrogen atom or a methyl group, and p is an integer of 3-6, reacting an amine compound containing active hydrogen with the modified epoxy resin (e) thus obtained, and further reacting a partially blocked isocyanate compound (h) with the modified epoxy-polyamine resin (f) thus obtained, said modified epoxy-polyamine resin (f) containing 3-40% by weight of alkylene oxide or alkylene glycol structural units originated from the diepoxide compound (a).
- 2. A composition set forth in claim 1 wherein the partially blocked isocyanate compound (h) and the modified epoxy-polyamine resin (f) are reacted in such a proportion that the solid content ratio of compound (h)/resin (f) becomes in the range of 1/20-1/1.
- 3. A resin composition for cationic electrodeposition paint comprising the composition set forth in claim 1.
- 4. A cationic electrodeposition coating bath comprising the composition set forth in claim 1.
- 5. An article coated by using the composition set forth in claim 1.
