摘要： This invention is intended to provide a method for producing a resin composition used for paint which is preferable for improving dispersibility of pigments, thereby improving productivity. The method is characterized in that a plurality of pigments which consist a resin composition used for paint is mixed, the mixed pigments are dispersed at an optimal dispersion mixing ratio with a resin and a solvent, which has been found in advance using a Daniel Flow Point Method (a Flow Point Method), and then other components are added thereto to obtain the predetermined resin composition used for paint. It is particularly preferable for the resin composition used for paint to be an electrodeposition paint composition.

摘要： Cathodic electrodeposition paints of the type in which a cationically modified epoxy resin is crosslinked with a blocked polyisocyanate crosslinker are disclosed. The paint contains a cationically modified epoxy resin having at least one oxazolidone ring in the molecule and a Tg ranging between 0.degree. C. and 35.degree. C., and a blocked alicyclic polyisocyanate. The use of lead based anticorrosive pigments may be eliminated or substantially reduced. When the alicyclic polyisocyanate is a bicycloalkane polyisocyanate, the use of organic solvent may also be reduced.
