ABSTRACT:
A postal card or mailer construction comprising a cover sheet adhered to a base sheet is provided which is simple to manufacture and print by automated systems and which is capable of providing hidden confidential information to an addressee. Upon receipt, the addressee can readily peel back the cover sheet and read the confidential information. Through the use of a releasable adhesive, once delaminated, all surfaces of the postal card construction have nontacky surfaces, permitting easy handling and storage by the recipient. The construction includes a base sheet, a cover sheet overlying the base sheet, and a releasable adhesive securing a first surface of the cover sheet to a first surface of the base sheet such that the cover sheet and base sheet are readily separable. The releasable adhesive contains therein a first color former composition which, when exposed to a second color developer composition, forms a distinctive color. At least oen of the first and second compositions are contained in a plurality of capsules which rupture upon the application of an impact force on the cover sheet. When an imaging force is applied to the cover sheet, the capsules of the first composition are ruptured, mix with the second composition on the surface of the base sheet, and form a distinctive color to duplicate the information from the imaging force.
