A composition containing a novel vinyl-group-containing compound. This composition contains a vinyl-group-containing compound represented by general formula (1). In the formula: W.sup.1 and W.sup.2 represent a group represented by general formula (2) (where a ring (Z) is an aromatic hydrocarbon ring, X is a single bond or S, R.sup.1 is a single bond or a C1-4 alkylene group, R.sup.2 is a specific substituent group such as a monovalent hydrocarbon, and m is an integer equal to 0 or higher), a group represented by general formula (4) (where the ring (Z), X, R.sup.1, R.sup.2, and m are as previously stated), a hydroxyl group, or a (meth)acryloyloxy group; rings (Y.sup.1, Y.sup.2) are aromatic hydrocarbon rings; R represents a single bond or a specific divalent group; R.sup.3a and R.sup.3b represent a cyano group, a halogen atom, or a monovalent hydrocarbon group; and n1 and n2 are integers of 0-4. ##STR00001##

Arylclobutene-containing multi-functional monomers are useful in the preparation of arylcyclobutene-based polymer coatings. Compositions comprising one or more arylclobutene-containing multi-functional monomers and one or more oligomers comprising as polymerized units one or more arylcyclobutene monomer provide arylcyclobutene-based polymer coatings having reduced stress. Such compositions are useful in the manufacture of electronic devices.
