Low viscosity, radiation curable fluid formulations that can be used advantageously as radiation curable, inks. The formulations are easily prepared for use in ink jet systems. The viscosity of the compositions is low enough so that conventional solvent is not required in order to satisfy the requisite low ink jet viscosity specifications. After curing, the compositions form durable, weatherable, abrasion resistant, printed images on a wide variety of porous and nonporous substrates. The formulations are very suitable for outdoor printing applications, especially for printing outdoor graphics onto a variety of surfaces, including vinyl or other polymer films commonly used for signage, retroreflective signage or other retroreflective items. L'invention concerne des formulations fluides à faible viscosité, séchables par rayonnement, pouvant être utilisées avantageusement comme encres séchables par rayonnement. Ces formulations, de préparation facile, sont destinées à des systèmes d'impression à jet d'encre. La viscosité des compositions est suffisamment faible, de sorte qu'il est inutile d'employer un solvant classique pour répondre aux spécifications de viscosité faible requises dans l'impression à jet d'encre. Après séchage, les compositions forment des images imprimées durables, résistant aux intempéries et à l'abrasion, sur un large éventail de substrats poreux et non poreux. Ces formulations conviennent particulièrement bien pour des applications d'impression extérieures, notamment pour imprimer des graphismes extérieurs sur diverses surfaces, y compris le vinyle ou d'autres films polymères utilisés couramment dans la signalisation, la signalisation par rétroréflexion ou d'autres articles rétroréfléchissants.
