Abstract
A mailer or business form is provided including a coating of a first colorless reactant on one sheet thereof and a transparent patch overlying the coating. The surface of the patch facing the sheet includes a coating of a second colorless reactant such that when the transparent patch is impacted by an imaging force, a visible image is formed which may be viewed.
Claims17
A mailer or business form comprising,
- at least one exterior sheet having first and second major surfaces,
- a transparent patch overlying at least a portion of said first surface of said sheet, the surface of said transparent patch facing said sheet including a coating comprising solvent soluble, water insoluble dye particles and an encapsulated solvent;
- said encapsulated solvent adapted to dissolve said dye particles upon the impact of an imaging force on said transparent patch to form a visible image within said coating which is viewable through said transparent patch.
A mailer or business form comprising,
- at least one exterior sheet having first and second major surfaces, said first surface of said sheet including a coating of a first substantially colorless reactant on at least a portion thereof which, when combined with a second substantially colorless reactant at a later time, reacts to form a colored composition which yields a visible image;
- and
- a transparent patch overlying at least a portion of said first colorless reactant on said first surface of said sheet, the surface of said transparent patch facing said sheet including said second colorless reactant coated thereon;
- said first and second reactants adapted to be combined upon the impact of an imaging force on said transparent patch to form said visible image on said first surface which is viewable through said transparent patch.

A mailer or business form comprising,
- at least one exterior sheet having first and second major surfaces,
- a transparent patch overlying at least a portion of said first surface of said sheet, the surface of said transparent patch facing said sheet including a coating of a first substantially colorless reactant and a second substantially colorless reactant, which, when combined, form a colored composition which yields a visible image, at least one of said first and second reactants being contained in a plurality of microcapsules which rupture upon the application of an imaging force on said transparent patch to form said visible image within said coating which is viewable through said transparent patch.
