Abstract:
1. A method of curing a composition comprising applying the composition to a three-dimensional substrate and curing by plasma in a plasma discharge chamber wherein the composition comprises (d) and either (a), (b), (c), a mixture of (a) and (b), or a mixture of (a) and (c), wherein (a) is at least one free-radical-polymerisable compound, (b) is at least one compound that, under the action of an acid, is able to enter into a polymerisation, polycondensation or polyaddition reaction, (c) is at least one compound that, under the action of a base, is able to enter into a polymerisation, polycondensation or polyaddition reaction, and (d) is at least one photolatent compound that is activatable by plasma discharge selected from the group consisting of formula I, II and IV; formula I being wherein R R R or R R or a monovalent linear or branched siloxane radical; n is a number from 1 to 10; R R R R a and b are each independently of the other a number from 1 to 12; X is S, O or NR R R R formula II being wherein R R R R R R and formula IV being wherein R R R R or the substituents OR R R Y is C 1 -C 20 alkyl, phenyl, naphthyl, phenyl-C 1 -C 4 alkyl or a monovalent linear or branched siloxane radical; Y —CH 2 —, —CH 2 CH(OH)CH 2 O—Y 2 —OCH 2 CH(OH)CH 2 —, —CH 2 CH(OH)CH 2 —, divalent linear or branched siloxane radical; Y or a divalent linear or branched siloxane radical; R R
