Abstract
A decorative paper sheet for use in preparing a decorative laminate is made up of a matrix containing from about 15 to about 60 weight percent of cellulose and from about 40 to about 85 weight percent of cellulose acetate. The sheet also contains a plasticizer for the cellulose acetate in an amount ranging from about 40 to about 90 weight percent based on the weight of the cellulose acetate in said matrix. A filler material may be present in the sheet in an amount ranging from about 1 to about 18 weight percent based on the weight of the matrix. A low pressure laminate may be made from sheet and a structural substrate therefor by application of heat and pressure. The plasticized cellulose acetate fuses and resolidifies to bond the sheet to the structural substrate.
