Conventionally, anionic electrodeposition paints have been used for various purposes as primers. However, such a paint requires a high temperature of 160 to 180°C to be sufficiently cured, and is not suitable from the viewpoint of energy saving. In order to improve these drawbacks, efforts have been made to develop low-temperature, single-use anionic electrodeposition paints, but the current situation is that nothing useful has yet been found.

As a result of intensive research aimed at developing a low-temperature curing resin for coatings, the present inventors discovered that a low-temperature curing resin obtained from a condensate containing sorbic acid, maleic anhydride, epoxy resin, and unsaturated fatty acids as essential components was discovered. They discovered that it provides a coating film with excellent properties and good corrosion resistance, and is suitable as an anionic electrodeposition paint, and thus completed their invention.

Ctrocleposited Coatings J discloses an electrodeposition coating that cures at room temperature, but this is a two-component system, and one electrodeposition coating cannot be used for a long period of time. On the other hand, the electrocoating composition according to the invention is moldable, stable for a long time, and has an IQ of 80 to 1 (IQ"
It differs from conventional electrodeposition coating compositions in that it provides sufficient hardness, reparative properties and other general coating film properties when dried at a low temperature of C.

One or more of these fatty acids may be used. However, in order to obtain sufficient normal temperature drying properties, the resin composition of the present invention must be contained in a fatty acid-deficient resin raw material having at least one unsaturated carbon-carbon bond in an amount of 20 to 60% by weight. If it is less than 20, sufficient normal temperature drying properties cannot be obtained, and if it is more than 60, the initial hardness is low. More preferably, the resin raw material should contain 30 to 50% fatty acid by weight. The above-mentioned fatty acids may be introduced directly as fatty acids [7], or may be added as glycerin esters (oils and fats) of fatty acids.

The Diels-Alder reaction is generally carried out in parallel at temperatures above 50°C. Maleic anhydride (ηyp53°C1bp20
2℃) and norbic acid (mp 135℃, decomposition point 228℃)
It is important to carry out the Diels reaction at 140 to 190'C. Since the ring-opening reaction of Lr-oxy resin with carboxylic acid is promoted by an amine-based melting medium, a high 7-point amine such as dimethylbenolamine is used as the Z between the epoxy groups. . -O. . . It is effective to add it. The esterification reaction between alcohol group and carboxyl group is 150 to 250
It is unreasonable to do it at ℃. At temperatures above 200°C, the reaction of the unsaturated carbon-charcoal 5 double bonds of the unsaturated fatty acid and norbic acid becomes significant, so it is necessary to control the reaction temperature to avoid excessive reaction. In particular, since oxygen in the reaction system reacts with carbon-carbon double bonds, it is necessary to proceed with the reaction under an atmosphere of inert gas (nitrogen, carbon dioxide, etc.).
