Abstract

Abstract Temporarily bonded constructions, i.e., credit cards attached to paper stock for mailing to customers, may be prepared utilizing a non-pressure sensitive hot melt adhesive comprising 5-40% of specific A-B.A block copolymers and 95-60% plasticizing oil.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 123 words
A temporarily bonded construction comprising a plastic, paper, glass, ceramic or metal substrate attached to a paper base stock substrate utilizing a nonpressure sensitive hot melt adhesive, the adhesive consisting essentially of: (a) 5-40% by weight of at least one A-B-A block copolymer wherein the A blocks are non-elastomeric polymer blocks which, as homopolymers have glass transition temperatures above 20° C.,and the elastomeric polymer blocks B are isoprene or butadiene which is partially or substantially hydrogenated. (b) 95-60% by weight plasticizing oil, and (c) 0.1 to 2% by weight of a stabilizer; wherein up to 45% by weight of the oil may be replaced by a tackifying resin provided the quantity of said resin is not sufficient to render the adhesive pressure sensitive.
Claim 2
Dependent Claim 123 words
A temporarily bonded construction comprising a plastic, paper, glass, ceramic or metal substrate attached to a paper base stock substrate utilizing a nonpressure sensitive hot melt adhesive, the adhesive consisting essentially of: (a) 5-40% by weight of at least one A-B-A block copolymer wherein the A blocks are non-elastomeric polymer blocks which, as homopolymers have glass transition temperatures above 20° C.,and the elastomeric polymer blocks B are isoprene or butadiene which is partially or substantially hydrogenated. (b) 95-60% by weight plasticizing oil, and (c) 0.1 to 2% by weight of a stabilizer; wherein up to 45% by weight of the oil may be replaced by a tackifying resin provided the quantity of said resin is not sufficient to render the adhesive pressure sensitive.
Claim 3
Dependent Claim 19 words
The temporarily bonded contruction of claim 1 wherein the adhesive contains a block copolymer having a polystyrene non-elastomeric portion.
Claim 4
Dependent Claim 24 words
The temporarily bonded construction of claim 1 wherin the elastomeric ploymer block B in the adhesive is butadiene which is partially or substantially hydrogenated.
Claim 5
Dependent Claim 18 words
The temporarily bonded construction of claim 1 wherein the block copolymer in the adhesive is a polystyrene-polyisoprene-polystyrene copolymer.
Claim 6
Dependent Claim 37 words
The temporarily bonded construction of claim 1 wherein the adhesive consists essentially of 20 to 30% by weight of the block copolymer, 70 to 80% by weight of the oil and 0.25 to 1.0% of the stabilizer.
Claim 7
Dependent Claim 16 words
The temporarily bonded construction of claim 1 wherein the oil in the adhesive is mineral oil.
Claim 8
Dependent Claim 37 words
The temporarily bonded construction of claim 1 wherein up to 45% by weight of the oil is replaced by a tackifying resin provided the quantity of said resin is not sufficient to render the adhesive pressure sensitive.
Claim 9
Dependent Claim 17 words
The temporarily bonded contruction of claim 1 comprising a plastic card bonded to a paper base stock.
Claim 10
Dependent Claim 19 words
The temporarily bonded construction of claim 1 comprising a plastic or glass vial bonded to a paper base stock.
Claim 11
Dependent Claim 16 words
The temporarily bonded construction of claim 1 comprising a coin bonded to a paper base stock.
Claim 12
Dependent Claim 131 words
A methd for forming a temporarily bonded construction comprising the step of bonding a plastic, paper, glass, ceramic or metal substrate to a paper base stock substrate utilizing a non-pressure sensitive hot melt adhesive, the adhesive consisting essentially of: (a) 5-40% by weight of at least one A-B-A block copolymer wherein the A blocks are non-elastomeric polymer blocks which, as homopolymers have glass transition temperatures above 20° C., and the elastomeric polymer blocks B are isoprene or butadiene which is partially or substantially hydrogenated; (b) 95-60% by weight plasticizing oil, and (c) 0.1 to 2% by weight of a stabilizer; wherein up to 45% by weight of the oil may be replaced by a tackifying resin provided the quantity of said resin is not sufficient to render the adhesive pressure sensitive.
Claim 13
Dependent Claim 131 words
A methd for forming a temporarily bonded construction comprising the step of bonding a plastic, paper, glass, ceramic or metal substrate to a paper base stock substrate utilizing a non-pressure sensitive hot melt adhesive, the adhesive consisting essentially of: (a) 5-40% by weight of at least one A-B-A block copolymer wherein the A blocks are non-elastomeric polymer blocks which, as homopolymers have glass transition temperatures above 20° C., and the elastomeric polymer blocks B are isoprene or butadiene which is partially or substantially hydrogenated; (b) 95-60% by weight plasticizing oil, and (c) 0.1 to 2% by weight of a stabilizer; wherein up to 45% by weight of the oil may be replaced by a tackifying resin provided the quantity of said resin is not sufficient to render the adhesive pressure sensitive.
