Clean release laminate construction with latent image

A laminate construction comprising a face sheet having a releasable adhesive securing a first surface thereof to an opaque layer such that said face sheet and opaque layer are readily separable, said opaque layer being supported on a release liner and secured thereto by a pressure sensitive adhesive, said releasable adhesive containing therein a first composition which comprises a colorless reactant and which, when combined with a second colorless reactant at a later time, reacts to form a colored composition which yields a visible image, said first composition, when subjected to an imaging force, forms a latent image on said first surface of said face sheet and on said opaque layer.

A laminate construction comprising a backing sheet, a face sheet covering at least a portion of said backing sheet, and a releasable adhesive securing a first surface of said face sheet to a first surface of said backing sheet such that said face sheet and backing sheet are readily separable, said first surface of said face sheet having thereon a first composition which comprises a colorless reactant and which, when combined with a second colorless reactant at a later time, reacts to form a colored composition which yields a visible image, said first composition, when subjected to an imaging force, forms a latent image on said first surface of said face sheet.

The laminate construction comprising a face sheet having a releasable adhesive securing a first surface thereof to a pressure sensitive adhesive supported on a release liner such that said face sheet is readily separable from said pressure sensitive adhesive, said first surface of said face sheet containing thereon a first composition which comprises a colorless reactant and which, when combined with a second colorless reactant at a later time, reacts to form a colored composition which yields a visible image, said first composition, when subjected to an imaging force, forms a latent image on said first surface of said face sheet.

A laminate construction comprising a backing sheet, a face sheet covering at least a portion of said backing sheet, and a releasable adhesive securing a first surface of said face sheet to a first surface of said backing sheet such that said face sheet and backing sheet are readily separable, said first surface of said backing sheet having thereon a first composition which comprises a colorless reactant and which, when combined with a second colorless reactant at a later time, reacts to form a colored composition which yields a visible image, said first composition, when subjected to an imaging force, forms a latent image on said first surface of said backing sheet.

A laminate construction comprising at least three layers, wherein at least one of said layers comprises a face sheet and at least one other of said layers comprises a releasable adhesive securing a first surface of said face sheet to another layer in said laminate construction such that said face sheet is readily separable from said other layer, said laminate construction further including a first composition contained in said releasable adhesive, or on said first surface of said face sheet, or on a surface of said another layer which is in contact with said releasable adhesive, said first composition comprising a colorless reactant and which, when combined with a second colorless reactant at a later time, reacts to form a colored composition which yields a visible image, said first composition, when subjected to an imaging force, forming a latent image.
