Safety laminate and process for production thereof

A process for producing a safety laminate comprising at least two plates bonded to each other through an adhesive interlayer, which comprises

• applying an adhesiveness-imparting agent which is liquid at ambient temperature and is substantially non-adhesive to said plates to at least one of (a) the surface of each of said plates and (b) each surface to be bonded to said surface of said plates of a sheet-like adhesive material which is substantially non-adhesive, but which is latently adhesive, to said plates, said adhesiveness-imparting agent being a plasticizer capable of developing the latent adhesiveness of said sheet-like adhesive material to render it adhesive and wherein said sheet-like adhesive material is composed of a material selected from the group consisting of acrylic resins, polyvinylbutyral resins and polyester resins;
• and
• sandwiching said sheet-like adhesive material as an interlayer between two of said plates at ambient temperature to bond said plates through the interlayer of said sheet-like adhesive material when the adhesiveness is developed by the adhesiveness-imparting agent.
