Abstract
A laminated structure comprising at least two nonadhesive layers and at least one white-pigmented adhesive layer, wherein the white-pigmented adhesive layer is made of a composition stabilized against thermal crosslinking and consequent reduction of its melt index, consisting essentially of a uniform dispersion of alumina-coated titanium dioxide pigment in a blend of a matrix polymer which is a dipolymer of ethylene with an ethylenically unsaturated carboxylic acid or a terpolymer of ethylene with an ethylenically unsaturated carboxylic acid and with another ethylenically unsaturated comonomer, or with carbon dioxide or sulfur dioxide, with a stabilizing polymer which is a high melt index copolymer of ethylene with acrylic or methacrylic acid. Such laminated structures include, for example, toothpaste tubes, condiment pouches, traffic road signs, and roadway lane marking tapes.
