Abstract

Urethane acrylates of the general Formula (I), corresponding salts, solvates or solvates of a salt thereof:wherein R1, R2, R3, R4 and R5 each independently represent a substituent selected from the group consisting of hydrogen, halogens, C1-6-alkyls, trifluoromethyl, C1-6-alkylthios, C1-6-alkylselenos, C1-6-alkyltelluros, and nitro groups, with the proviso that at least one of R1, R2, R3, R4 and R5 is not hydrogen; R6 and R7 each independently represent a substituent selected from the group consisting of hydrogen and C1-6-alkyls; and A represents a saturated or unsaturated or linear or branched C1-6-alkyl radical or a polyalkylene oxide radical having 2-6 ethylene oxide or propylene oxide units; processes for producing and methods of using the same.
