ABSTRACT:
Disclosed is a modified epoxy resin composition comprising a resin having recurring units represented by the following general formula: ##STR1## wherein R.sub.1 stands for --CH.sub.2 --, >CHCH.sub.3,>C(CH.sub.3).sub.2, ##STR2## R.sub.2 stands for H or --CH.sub.3, R.sub.3 stands for H or a halogen atom, and having an epoxy group, a phenolic hydroxyl group and a primary alcoholic hydroxyl group as terminal functional groups in specific amounts.
This composition has a high reactivity with an active methylol group, and when this composition is combined with a curing agent resin such as an amino resin or a phenolic resin, a coating having an excellent bending processability is obtained.
