Title (EN) UV-CURABLE COMPOSITIONS COMPRISING ACYLPHOSPHINE OXIDE PHOTOINITIATORS
(FR) COMPOSITIONS DURCISSABLES PAR UV COMPRENANT DES PHOTO-INITIATEURS À BASE D'OXYDE D'ACYLPHOSPHINE
Abstract:
(EN) The present invention is drawn to UV-curable ink and coating compositions comprising acylphosphine oxide photoinitiators and acids. The acids may be inorganic or organic acids, or acids generated by a photoacid generator during UV-cure. Incorporation of the acids into the UV-curable ink and coating compositions results in a reduction of migratable aldehydes that are produced by acylphosphine oxide photoinitiators during UV-cure. The ink and coating compositions are particularly useful for use in applications that require low migration of low molecular weight materials, such as, for example, food packaging.
(FR) La présente invention concerne des compositions d'encre et de revêtement durcissables par UV comprenant des photo-initiateurs à base d’oxyde d'acylphosphine et des acides. Les acides peuvent être des acides minéraux ou organiques, ou des acides générés par un générateur de photoacide pendant le durcissement par UV. L'incorporation des acides dans les compositions d'encre et de revêtement durcissables par UV a pour résultat une réduction des aldéhydes pouvant migrer qui sont produits par des photo-initiateurs à base d'oxyde d'acylphosphine lors du durcissement par UV. Les compositions d'encre et de revêtement sont particulièrement utiles pour une utilisation dans des applications qui nécessitent une faible migration de matériaux à faible poids moléculaire, tels que, par exemple, l'emballage alimentaire.
