A gelled solid adhesive for coating substrates, typically paper. The adhesive can be made available in stick form and is easily applied on even coats to any surface area of the substrate. The adhesive has sufficient tack enabling the coated substrate to instantly adhere to essentially any free contact surface upon gently pressing the substrate to the free surface. The adhesive coated substrate is easily removable from the contact surface by manually lifting it therefrom. The adhesive permits readherence of the adhesive coated substrate to the same or different free contact surfaces. An adhesive coated paper substrate will readhere many times to free paper contact surface. The preferred gelled adhesive product is formed of an aqueous dispersion of components which include a natural rubber latex component, a friction reducing agent, a tackifier, an antioxidant, a gelling agent and surfactant. Preferred classes of tackifiers are anionic aqueous dispersion of hydrogenated esters of rosin and anionic aqueous dispersion of esters of hydrogenated rosin.

A thermal ink transfer laminate wherein an ink design is transferred from a carrier support to an article, typically paper, by application of a thermal printing element to the nontransfer side of the carrier. The thermal ink transfer laminate is composed of a carrier support of paper or plastic film overcoated on one side with a heat sensitive ink coating. The heat sensitive ink coating is composed of a hot melt mix containing a coloring agent, a wax binder, and a resin binder. The coloring agent contains a dye dispersed in an unsaturated fatty acid medium. The wax binder contains a paraffin and microcrystalline wax. The coloring agent in combination with the wax binder greatly facilitates attainment of a drastic drop in melt viscosity of the design layer during thermal transfer onto a receiving article. The degree of transfer attained is virtually complete resulting in a transferred image of exceedingly high image clarity and definition. The heat sensitive coating permeates fibrous receiving articles during thermal transfer resulting in a nonraised, firmly anchored abrasion-resistent transferred image.

A thermal ink transfer laminate wherein an ink design is transferred from a carrier support to an article, typically paper, by application of a thermal printing element, e. g. of the dot matrix type, to the nontransfer side of the carrier. The thermal ink transfer laminate is composed of a carrier support of paper or plastic film overcoated on one side with a heat sensitive transfer substrate. The heat sensitive transfer substrate contains an ink which preferably includes a coloring agent formed of a dye dispersed in an unsaturated fatty acid medium. A separate release layer may be included between the ink and carrier. The coloring agent facilitates attainment of a drastic drop in melt viscosity of the transfer laminate during thermal transfer onto a receiving article. The degree of transfer attained is virtually complete resulting in a transferred image of exceedingly high image clarity and definition when employing the thermal printing element. The heat sensitive coating permeates fibrous receiving articles during thermal transfer resulting in a nonraised, firmly anchored abrasion-resistant transferred image.

Electrosensitive recording using a composite structure formed by a base support for a resinous contrast layer containing silicon dioxide, with an overlying metallic surface provided by vapor deposition. The electrosensitive structure provides improved print quality for information recorded by electrically actuated stylii, with reduced debris accumulation.

A tab for adhesively securing and binding articles within looseleaf binders and like devices, where such articles cannot be conveniently provided with apparatus for engagement by the binder rings. The tab includes a central, apertured portion advantageously comprising bilaterally symmetric apertured sections separated by a central fold line, and wing portions, all adhesive-coated. The tab is prepared for use by folding the respective halves of the central tab portion against each other with apertures aligned. The tab may then be inserted in a binder ring, and the wings of the tab adhesively secured to the article to be bound. Advantageously a plurallity of such tabs are included in a tab stock, such tab stock including an adhesive coated tab substrate (preferably transparent) and backing sheet.
