Abstract
A decor sheet for use in decorative laminates wherein the sheet is treated with a sizing agent to reduce its capacity for a laminating resin and enhance its opacity; in a preferred embodiment, the resin-impregnated decor sheet exhibits a resin gradient in the thickness direction to provide a decor sheet having a resin-rich top layer and a resin-starved bottom layer; in accordance with a preferred embodiment, the resin gradient is achieved by differentially sizing the bottom versus the top surface of the decor sheet; a decorative laminate employing such decor sheets are described.
Claims19
A decorative laminate comprising a laminating resin-impregnated decor sheet and a plurality of laminating resin-impregnated core sheets, said decor sheet being treated with a sizing agent such that said sheet is only partially impregnated with said laminating resin, said sizing agent being a sizing agent which is capable of substantially reducing the amount of laminating resin absorbed by said decor sheet.
The decor sheet for use in a decorative laminate comprising a fibrous mat having a top portion and a bottom portion in the thickness direction of the mat, wherein the bottom portion of said fibrous mat includes a sizing agent and the top portion of said fibrous mat is essentially free of said sizing agent such that said top portion absorbs at least 10% more laminating resin per unit volume than said bottom portion when the decor sheet is saturated with a laminating resin.
A decorative laminate comprising a laminating resin-impregnated decor sheet and a plurality of laminating resin-impregnated core sneers, wherein said decor sheet comprises a fibrous mat having a top portion and a bottom portion in the thickness direction of the sheet, wherein the bottom portion of said fibrous mat includes a sizing agent and the top portion of said fibrous mat is essentially free of said sizing agent such that said top portion absorbs at least 10% more laminating resin per unit volume than the bottom portion when the decor sheet is impregnated with said resin.
