Abstract
Abstract A gelled solid adhesive for coating substrates, typically paper. The adhesive can be made available in stick form and is easily applied in 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 rubber such as 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.

Claims Analysis
Total Claims: 30
Claim 1
Independent Claim
140 words
A gelled adhesive product in solid form comprising: a rubber component; a water soluble or water dispersible tackifying agent; and a gelling agent; said gelled adhesive product having the combination of properties resulting in an adhesive coatable onto a substrate surface area by gliding the adhesive product over the substrate surface, the adhesive having sufficient tack permitting the adhesive coated area on said substrate to immediately adhere to a solid contact surface as said adhesive coated substrate is pressed against the contact surface, the adhesive also having sufficient release property permitting removal of said adhesive coated substrate from said contact surface upon lifting the coated substrate from the contact surface, said adhesive having the additional property permitting said same adhesive coated substrate to readhere to a solid contact surface upon pressing said same coated substrate thereto without applying additional adhesive.
Claim 2
Dependent Claim
