A transfer-pad printing aqueous composition comprising effective amounts of a water soluble polymer, an opacifier, and a dispersant and optionally a colorant and/or release agent is provided. The composition is particularly suited for use with silicone rubber transfer-pads to print alphanumeric patterns on curved or spherical surfaces such as opthalmic lenses.
L'invention concerne une composition aqueuse d'encre d'imprimerie pour tampon de report, contenant les quantités requises d'un poylmère soluble dans l'eau, d'un opacifiant, d'un dispersant et, éventuellement, d'un colorant et/ou d'un agent de libération. Cette composition se prête particulièrement à une utilisation avec des tampons de report en caoutchouc de silicone qui permettent d'imprimer des motifs alphanumériques sur des surfaces courbes ou sphériques telles que des verres ophtalmiques.
