A method for curing aminoplasts, during which layers having layer
thicknesses of up to 300 um or filaments and fiber fibrids having a
diameter of up to 300 um, which consist of: i) 95 to 99.95% by mass of
solvent-free meltable aminoplast polycondensates with molar masses
ranging from 1000 to 300000; j) 5 to 0.05% by mass of curing agents,
which can be activated by actinic light and which are comprised of
acidifiers of the blocked sulfonic acid and/or halogen-substituted
triazine derivative and/or onium salt type, and optionally; k) 1 to 20%
by mass, with regard to the meltable aminoplast polycondensates, of
unmodified and/or modified maleic anhydride copolymers, and/or; i) 0.1 to
5% by mass, with regard to the meltable aminoplast polycondensates, of
nanoparticles. The aminoplasts are cured by irradiating them with actinic
light at a temperature between the melting point of the aminoplast
polycondensate and the thermoinduced decomposition temperature of the
light-activatable curing agents. This method enables the production of,
preferably, textile fabrics or coatings.
