    摘要： A backing sheet for the weathering-resistant coating of thin, plane backings in continuous presses without recooling comprising(A) a paper impregnated with curable melamine resin in an amount of 40 to 60 weight percent of aminoplast resin, based on the weight of the paper, in the dried state, and(B) a coating of curable acrylic resin on the impregnated paper in an amount of 60 to 150 g/m.sup.2, the curable acrylic resin being a copolymer obtained by polymerizing:(a) 60 to 80 weight percent of one or more alkyl methacrylate esters with 1 to 20 carbon atoms in the alkyl radical;(b) 1 to 30 weight percent of one or more alkyl acrylate esters with 1 to 8 carbon atoms in the alkyl radical;(c) 1 to 20 weight percent of an N-methoxymethylamide of acrylic acid, methacrylic acid, or mixtures thereof;(d) 1 to 20 weight percent of a hydroxyalkyl ester of acrylic or methacrylic acid, with 2 to 4 carbon atoms in the alkyl radical;(e) 1 to 20 weight percent of acrylamide or methacrylamide, the molar ratio of component (c) to the sum of (d) and (e) being about 1:1 and the ratio of (d) to (c) being 4:1 to 1:4;(f) 0 to 35 weight percent of acrylonitrile,the sum of components (a) to (f) being 100 weight percent. The so-called endless laminates, fabricated by using the inventive backing sheet containing the selected acrylic resin, have a defect-free surface, even though the laminates were not recooled.
