Abstract
Abstract A repulpable pressure-sensitive adhesive stock for labels and tapes is provided comprising a paper face material providing a surface active agent and having thereon a discontinuous pattern of a pressure-sensitive adhesive segements. The surface active agent acts to detackify the pressure-sensitive adhesive segment in pulping of the construction to prevent their agglomeration.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
109 words
A repulpable pressure-sensitive adhesive stock which comprises: a) a backing formed of repulpable cellulosic fibers and providing opposed backing surfaces; b) a tacky pressure-sensitive adhesive layer provided on at least one surface of the backing, said pressure-sensitive adhesive layer formed of a substantially discontinuous pattern of discrete water insoluble pressure-sensitive adhesive segments; and c) at least one surface active agent selected from the group consisting of surfactants and detergents provided by the backing, said surface active agent having an affinity for the pressure-sensitive adhesive and provided in quantity sufficient to detackify the discrete pressure-sensitive adhesive segments to prevent agglomeration of the pressure-sensitive adhesive segments upon pulping of the backing.
Claim 2
Dependent Claim
109 words
A repulpable pressure-sensitive adhesive stock which comprises: a) a backing formed of repulpable cellulosic fibers and providing opposed backing surfaces; b) a tacky pressure-sensitive adhesive layer provided on at least one surface of the backing, said pressure-sensitive adhesive layer formed of a substantially discontinuous pattern of discrete water insoluble pressure-sensitive adhesive segments; and c) at least one surface active agent selected from the group consisting of surfactants and detergents provided by the backing, said surface active agent having an affinity for the pressure-sensitive adhesive and provided in quantity sufficient to detackify the discrete pressure-sensitive adhesive segments to prevent agglomeration of the pressure-sensitive adhesive segments upon pulping of the backing.
Claim 3
