Abstract

Abstract A laminated material is formed of a layer of polyurethane or polyether and a layer of extruded polyester. The polyester adhesive layer, which may contain five to fifteen percent by weight of polyurethane homogeneously mixed therein, is bonded to the layer of polyurethane or polyether under pressure at a sufficiently high temperature to permit an even viscous molecular flow between adjacent surfaces of the layers. When the layer is polyurethane, the temperature is above the softening point of polyurethane so that it is high enough to remove at least enough of the toluene solvent from the layer of polyurethane so that curling is prevented. When the laminated material is applied to a material with sufficient pressure and heated sufficiently that the layer of polyester becomes adhesive, the laminated material adheres to the material against which the layer of polyester is pressed. Thus, the laminated material has particular utility as a letter, numeral, or design for a sport uniform or wearing apparel, for example, of any material.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 107 words
A laminated material for adhering to a material when subjected to a selected temperature and pressure for a selected period of time including a first layer selected from the group consisting of polyurethane and polyether, a second layer of polyester, said first and second layers being bonded to each other, said second layer having the same coefficient of expansion and contraction as said first layer, said first layer being treated to prevent it from curling, and said second layer becoming adhesive for adhering to a material when said bonded first and second layers are subjected to the selected temperature and pressure for the selected period of time.
Claim 2
Dependent Claim 107 words
A laminated material for adhering to a material when subjected to a selected temperature and pressure for a selected period of time including a first layer selected from the group consisting of polyurethane and polyether, a second layer of polyester, said first and second layers being bonded to each other, said second layer having the same coefficient of expansion and contraction as said first layer, said first layer being treated to prevent it from curling, and said second layer becoming adhesive for adhering to a material when said bonded first and second layers are subjected to the selected temperature and pressure for the selected period of time.
Claim 3
Dependent Claim 25 words
The laminated material according to claim 1 in which a letter or the like is formed from the laminated material for adhering to the material.
Claim 4
Dependent Claim 14 words
The laminated material according to claim 1 in which said first layer is polyurethane.
Claim 5
Dependent Claim 30 words
The laminated material according to claim 3 in which said second layer includes polyurethane mixed with the polyester with polyurethane being five to fifteen percent by weight of the mixture.
Claim 6
Dependent Claim 35 words
The laminated material according to claim 1 in which said first layer has a thickness no greater than five mils and said second layer has a thickness less than the thickness of said first layer.
Claim 7
Dependent Claim 20 words
The laminated material according to claim 5 in which said second layer has a thickness no greater than three mils.
Claim 8
Dependent Claim 14 words
The laminated material according to claim 6 in which said first layer is polyurethane.
Claim 9
Dependent Claim 30 words
The laminated material according to claim 7 in which said second layer includes polyurethane mixed with the polyester with polyurethane being five to fifteen percent by weight of the mixture.
Claim 10
Dependent Claim 25 words
The laminated material according to claim 8 in which a letter or the like is formed from the laminated material for adhering to the material.
