title: Allergic contact dermatitis from ultraviolet cured inks. Allergic contact sensitization to acrylates.
abstract: Eight men employed in the manufacture of ultraviolet cured inks developed allergic contact dermatitis predominantly on the exposed areas. Patch testing revealed sensitization to trimethylol propane triacrylate in seven employees, to 1,6-hexanediol diacrylate in six employees, to pentaerythritol triacrylatylate in four employees and to epoxy acrylate oligomers in three employees. Either cross-sensitization or concomitant sensitization may have accounted for the multiple reactions in several employees. One sensitized employee was patch tested with four different commercially available epoxy acrylate oligomers and reacted only to two, suggesting that variations possibly in chain length between these oligomers are important variables in the allergic reactions. The polyfunctional acrylic monomers and certain epoxy acrylate oligomers should be handled carefully to avoid the development of allergic contact dermatitis.
