1. A bonding process in which two substrates are bonded together by applying to a surface of at least one of the substrates a curable, not yet cured, liquid adhesive that
(a) in a first component comprises at least one compound A; and
(b) in a second component comprises at least one curing compound B selected from compounds having at least one functional group selected from primary amine groups and secondary amine groups, and wherein the first component, the second component, and/or a further component of the adhesive comprises at least one compound C that has at least one functional group reactive with an —SH group, wherein the at least one functional group has an ethylenically unsaturated bond,
wherein the substrates being bonded are the same or different from one another and are selected from the group consisting of metal, wood, glass, plastic shaped bodies, plastic films, paper, and paperboard,
wherein at least two of the at least one compounds A, B, and C are polyfunctional, and
wherein the at least one compound A has the formula (I)
