Claim 6:
7. The method according to claim 1, wherein the crosslinking agents are selected from:
acids photo-generated from a salt selected from onium salts, such as iodonium, sulfonium, pyridinium, alkoxypyridinium, phosphonium, oxonium, or diazonium salts;
bases photo-generated from derivatives selected from carbamates, acyloximes, ammonium salts, sulfonamides, formamides, amineimides, α-aminoketones, amidines;
thermally activatable catalysts selected from chemical derivatives for generating a thermally activated acid proton, such as ammonium salts like ammonium triflate, ammonium trifluoroacetate, or ammonium trifluoromethane sulfonate, pyridinium salts such as pyridinium para-toluenesulfonate, phosphoric or sulfuric or sulfonic acids, or onium salts such as iodonium or phosphonium salts, or imidazolium salts, amines or polyamines, such as diethylene triamine, isophorone diamine, 4,4′-diaminodiphenylsulfone, hexamethylene diamine, dicyandiamide (cyanoguanidine), or ascorbic acid and its derivatives, selected from sodium or magnesium ascorbate or sodium, magnesium or ammonium ascorbylphosphate, as well as the various possible isomers (diastereoisomers, enantiomers) of ascorbic acid; uric acid; phenol, polyphenols and phenolic derivatives such as hydroquinone, resorcinol, 2,4-pentanedione, malonaldehyde (propanedial), tartronaldehyde (2-hydroxypropanedial), furanone and more generally reductones;
thermal radical initiators selected from derivatives of the organic peroxide type, or derivatives having an azo-type chemical function, such as azobisisobutyronitrile, or derivatives of the alkyl halide type;
radical photoinitiators selected from acetophenone, benzophenone, organic peroxides, phosphines, xanthones, thioxanthones, quinones, α-hydroxyketones or diazonaphthoquinone, α-aminoketones, benzil, benzoin derivatives.
