A laminate for use as a sticker, identity card, or the like has a back sheet having a front face bearing indicia and a back face that is provided with adhesive to adhere it to a substrate. The front face is adhered to a transparent cover sheet by means of a plurality of spaced-apart adhesive zones, so that any attempt to peel apart the laminate will result in tearing of the back sheet at these zones. In addition the adhesive on the back sheet may be provided in zones alternating with the zones on the front of the back sheet, so that irreversible destruction of this back sheet is ensured in the event of tampering.

A laminate comprising: a relatively fragile back sheet having a back face and a front face; means on said back face of said fragile back sheet for securing same flatly on a substrate; indicia on said front face of said fragile back sheet; an at least partially transparent and relatively strong front sheet having a back face overlying said front face of said fragile back sheet; and means forming a plurality of relatively strong bonds between said back face of said strong front sheet and said front face of said fragile back sheet at spaced-apart bonded zones separated by and defining bond-free zones where said strong and fragile sheets are not bonded together, said indicia partially overlapping said bonded zones and partially overlapping said bond-free zones, whereby an attempt to separate said strong and fragile sheets will tear said relatively fragile back sheet and destroy said indicia.
