International ClassesC08F 020/20C08F 020/26 C08L 031/04 C08L 033/10 AbstractA curable topcoat composition and apparatus useful for preparing stable data carrying devices, such as multi-layered laminates, and methods for preparing and using the composition. The composition includes a polymerizable composition and a polymeric binder. The polymerizable composition includes hard and flexible polymerizable subunits in a ratio that optimizes flexibility while retaining good adhesion and plasticizer resistance. In a preferred embodiment, a polymerization initiator is also included in the composition. Optionally, a chain transfer agent may also be added to the composition. The composition is substantially plasticizer free. The methods of using the composition include incorporating the composition into a topcoat film useful for storing the topcoat composition prior to use in preparing data carrying devices, such as cards.Field of SearchChemical reactant has two or more ethylenic groupsCarboxylic acid or derivative Oxygen other than as part of a COO-group Chemical reactant has two or more ethylenic groups At least two solid polymers derived from ethylenic monomers only Ester derived from an unsaturated carboxylic acid Ester contains an oxygen atom other than as a carboxylic acid ester group Ester is derived from an unsaturated carboxylic acid Ester derived from an unsaturated carboxylic acid is reacted in the presence of a solid polymer IMAGED PRODUCT Including resin or synthetic polymer |
