N-substituted maleimide represented by formula (2):
is produced from N-substituted maleamic acid monoester represented by formula (1):
in the presence of an acid catalyst by elimination of an alcohol from the monoester. The above N-substituted maleamic acid monoester represented by formula (1) is produced by esterification of N-substituted maleamic acid represented by formula (3):
with an alcohol R² -OH in the presence of an acid catalyst.

A water-based adhesive for polarizing elements which comprises a polyvinyl alcohol resin, a resin having a maleic anhydride skeleton in the structure, and a crosslinking agent in a weight proportion of 100/(1-1,1000)/(0.5-5,000). It is easy to handle because it is of the water-based one-pack type. The adhesive has sufficient adhesion strength even in a high-temperature high-humidity atmosphere. The adhesive contains boron
