Abstract
Abstract A process for the formation of the hinge joints on bound book blocks using a hot melt pressure sensitive adhesive comprising: (a) 20 to 35% by weight of an A-B-A block or A-B-A-B-A-B multi-block copolymer where the A component is styrene and the B component is butadiene or hydrogenated butadiene and the copolymer contains at least 28 parts styrene per 100 parts copolymer; (b) 45 to 70% by weight of a compatible tackifying resin; (c) 5 to 30% by weight of a plasticizing oil; (d) 0 to 5% by weight of a petroleum derived wax; and (e) 0.1 to 2% by weight of a stabilizer.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
174 words
A process for the formation of hinge joints on bound book blocks comprising the steps of applying a molten film of a hot melt adhesive to the outer sheet of each side of the book block on an area immediately adjacent the bound edges and for a length substantially coterminus with the bound edges; applying a cover thereto and exerting pressure on the book cover in the area of the hot melt film wherein the a hot melt adhesive is a pressure sensitive adhesive composition comprising: (a) 20 to 35% by weight of an A-B-A-B-A-B block or multi-block copolymer where the A component is styrene and the B component is butadiene or hydrogenated butadiene; and wherein the styrene is present in an amount of at least 28 parts per 100 parts copolymer; (b) 45 to 70% by weight of a compatible tackifying resin; (c) 5 to 30% by weight of a plasticizing oil; (d) 0 to 5% by weight of a petroleum derived wax; and (e) 0.1 to 2% by weight of a stabilizer.
