To provide a sealing material composition which can give a card having the excellent adhesion between a substrate sheet and a cover sheet, little unevenness, moderate flexibility as well as high reliability, and to provide a process for preparing the card with the above characteristics using this sealing material composition.
A sealing material composition for cards contains (A) an ionizing radiation-polymerizable acrylate compound and (B) a multifunctional isocyanate of 1-40 pts.wt. based on 100 pts.wt. of (A) component and is to be cured by irradiation of an ionizing radiation. In addition, a card is prepared by interposing a coating layer 5 made of the sealing material composition between a substrate sheet 3 and a cover sheet 4 and by irradiating the ionizing radiation to thereby cure the coating layer.
