Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
108 words
A decorative laminate comprising: a paper core backing layer; a decorative paper facing sheet having a first exterior surface laminated to said backing layer; and a coating including at least two dissimilar resins applied prior to laminating said facing sheet to said backing layer on a second exterior surface of said decorative facing sheet, one of said resins being a liquid melamine impregnating resin and another of said resins being a surface coating resin that melts and flows under heat and pressure during lamination to form a laminating surface having one or more of the following properties including enhanced wearability, chemical, thermal, ultra-violet radiation resistance or abrasion resistance.
Claim 2
Dependent Claim
108 words
A decorative laminate comprising: a paper core backing layer; a decorative paper facing sheet having a first exterior surface laminated to said backing layer; and a coating including at least two dissimilar resins applied prior to laminating said facing sheet to said backing layer on a second exterior surface of said decorative facing sheet, one of said resins being a liquid melamine impregnating resin and another of said resins being a surface coating resin that melts and flows under heat and pressure during lamination to form a laminating surface having one or more of the following properties including enhanced wearability, chemical, thermal, ultra-violet radiation resistance or abrasion resistance.
Claim 3
Dependent Claim
36 words
A decorative laminate in accordance with claim 1, wherein said surface coating resin is selected from the group consisting essentially of polyester, polyurethane, epoxy, polyvinyl chloride, acrylic, and mixtures of two or more of the foregoing.
Claim 4
Dependent Claim
41 words
A laminate in accordance with claim 1, wherein said coating surface includes a mixture of an abrasion resistant hard mineral having a particle size of between about 1-200 microns in a concentration sufficient to provide abrasion resistance without interfering with visibility.
Claim 5
Dependent Claim
39 words
A laminate in accordance with claim 1, wherein said abrasion resistant mineral particles are selected from the group consisting of alumina, silica, zirconium oxide, cerium oxide, glass beads, diamond dust and mixtures of two or more of the foregoing.
Claim 6
Dependent Claim
27 words
A laminate in accordance with claim 3, wherein said abrasion resistant mineral is alumina and wherein said alumina is chemically bound to said melamine with a silane.
Claim 7
Dependent Claim
126 words
A decorative laminate comprising: a paper core backing layer; a decorative paper facing sheet having a first exterior surface laminated to said backing layer and having a pearlescent ink on a second exterior surface; and a coating including at least two dissimilar resins applied prior to laminating said facing sheet to said backing layer on the second exterior surface of said decorative facing sheet, one of said resins being a liquid melamine impregnating resin and another of said resins being a surface coating resin that melts and flows under heat and pressure during lamination and which has a refractive index in the cured laminate dissimilar from the refractive index of the pearlescent ink on the decorative facing sheet to form a laminate having a pearlescent appearance.
Claim 8
Dependent Claim
126 words
A decorative laminate comprising: a paper core backing layer; a decorative paper facing sheet having a first exterior surface laminated to said backing layer and having a pearlescent ink on a second exterior surface; and a coating including at least two dissimilar resins applied prior to laminating said facing sheet to said backing layer on the second exterior surface of said decorative facing sheet, one of said resins being a liquid melamine impregnating resin and another of said resins being a surface coating resin that melts and flows under heat and pressure during lamination and which has a refractive index in the cured laminate dissimilar from the refractive index of the pearlescent ink on the decorative facing sheet to form a laminate having a pearlescent appearance.
Claim 9
Dependent Claim
46 words
A decorative laminate in accordance with claim 6, wherein the surfacing coating resin is a polymer which melts and flows under heat and pressure selected from the group consisting essentially of polyester, polyurethane, epoxy, polyvinyl chloride, acrylic and mixtures of two or more of the foregoing.
Claim 10
Dependent Claim
41 words
A laminate in accordance with claim 6, wherein said coating further includes a mixture of an abrasion resistant hard mineral having a particle size of between about 1-200 microns in a concentration sufficient to provide abrasion resistance without interfering with visibility.
Claim 11
Dependent Claim
39 words
A laminate in accordance with claim 6, wherein said abrasion resistant mineral particles are selected from the group consisting of alumina, silica, zirconium oxide, cerium oxide, glass beads, diamond dust and mixtures of two or more of the foregoing.
Claim 12
Dependent Claim
27 words
A laminate in accordance with claim 8, wherein said abrasion resistant mineral is alumina and wherein said alumina is chemically bound to said melamine with a silane.
