    • A thermosetting composition which comprises:(D) a self-crosslinking compound having in the molecule (a) one or more functional groups of the formula (2): ##STR1## wherein R.sup.5, R.sup.6 and R.sup.7 are each hydrogen or an organic group of 1 to 18 carbons, R.sup.8 is an organic group of 1 to 18 carbons, Y.sup.2 is oxygen or sulfur, or R.sup.7 and R.sup.8 are bonded with each other to form a heterocyclic structure which comprises Y.sup.2 as the heteroatom component; and (b) one or more reactive functional groups which can form a chemical bond with carboxyl functional groups which are regenerated from (a) by heating; (C) optionally, a thermal latent acid catalyst which is activated during curing of the composition by heating; (A) optionally, a compound having in the molecule two or more functional groups of the formula (1): ##STR2## wherein R.sup.1, R.sup.2 and R.sup.3 are each hydrogen or an organic group of 1 to 18 carbons, R.sup.4 is an organic group of 1 to 18 carbons, Y.sup.1 is oxygen or sulfur, or R.sup.3 and R.sup.4 are bonded with each other to form a heterocyclic structure which comprises Y.sup.1 as the heteroatom component; and/or, (B) optionally, a compound having in the molecule two or more reactive functional groups which can form a chemical bond by heating with either one or both of the functional group of the formula (1) and the functional group of the formula (2).
