Metal adhesive compositions and method of bonding articles therewith

A method for adhering a metal using a composition comprising an unsaturated thiirane compound having at least one thiirane group bonded with a saturated carbon atom and having at least one olefin-type double bond;

• wherein the unsaturated thiirane compound is represented by general formula I:
• where R1 is a group represented by
• or general formula (II):
• R2 is an organic group having a carbon number of 1 through 40, and each of R3 and R4 is independently an organic group having a carbon number of 1 to 40, hydrogen, a thiirane group, or halogen, R5 is hydrogen or a methyl group, X is —COO—, —CONH—, —NHCO—, or —O—, and each of n and m is independently 0 or 1, wherein in the case where at least one of R3 and R4 is an organic group, at least two of R2, R3 and R4 can be bonded to each other to form a cyclic structure, and wherein, when n=0, m=1, X is —COO—, and R3 and R4 are both H, then R1 is
