Sealing material composition for cards and process for producing cards using the composition

摘要

A sealing material composition for cards which comprises (A) an acrylate compound polymerizable by an ionizing radiation and (B) 1 to 40 parts by weight of a polyfunctional isocyanate compound per 100 parts by weight of the acrylate compound and can be cured by irradiation of the ionizing radiation and a process for producing cards comprising disposing a coating layer comprising the above sealing material composition between a substrate sheet and a cover sheet and curing the coating layer by irradiation of an ionizing radiation. The sealing material composition gives excellent adhesion between a substrate sheet and a cover sheet and provides cards having faces with little unevenness, suitable flexibility and excellent reliability. The process provides cards having the above characteristics.
