An adhesive system comprising an activatable, non-tacky cohesive material dispersed in a nonadherent material, said nonadherent material reducing the coefficient of friction of said cohesive material and rendering said cohesive material non-coherent; and a plurality of microcapsules dispersed in said nonadherent material and said cohesive material, said microcapsules encapsulating a solvent for said cohesive and being rupturable upon the application of pressure, wherein upon the application of pressure, the microcapsules rupture and release said solvent and said solvent dissolves said cohesive material such that said cohesive material becomes coherent.

Microcapsule-containing cohesive coating

Disclosed is a developer sheet useful in forming reproductions having a glossy finish, or in forming transparencies comprising:

Developer sheet useful in providing transparencies or reproductions

A method and apparatus glosses a developer sheet which has a resin layer coated on one side thereof which glosses at a predetermined temperature T. The sheet is placed with the resin side thereof in contact with a conductive heating element, preferably a porous belt. Heat is applied to the resin side of the sheet by the heating element to bring the sheet from its ambient temperature to a temperature just below the glossing temperature T.

Two-stage method and apparatus for glossing a developer sheet

The present invention provides a developer sheet useful in forming reproductions having a controllable gloss finish and reduced photolytic yellowing. The developer sheet comprises a support having a layer of a finely divided, thermoplastic, phenolic developer material and an anti-yellowing agent on the surface thereof. The phenolic developer material is capable of reacting with a color former to produce a visible image and is capable of coalescing into a thin film which imparts gloss to the image upon the application of heat.
