Abstract:
Provided is a laminated sheet including an upper paper layer and a release sheet layer, the upper paper layer including synthetic paper and an adsorbing layer, the synthetic paper, the adsorbing layer and the release sheet layer, in order, being laminated, wherein the adsorbing layer is a foam sheet of a resin composition, the resin composition containing crosslinking resultant of 100 parts by mass of a (meth)acrylic acid ester copolymer resin and 1 to 20 parts by mass of a carbodiimide crosslinking agent, the (meth)acrylic acid ester copolymer resin having a N-methylol group, a glass transition temperature of the (meth)acrylic acid ester copolymer resin being no more than −10° C., the release sheet layer consists of a thermoplastic resin sheet, and a rate of tensile elastic moduli is 0.1 to 10, the rate being calculated from a tensile elastic modulus of the upper paper layer and a tensile elastic modulus of the release sheet layer, and a peel strength of the adsorbing layer and the release sheet layer is 5 to 30 N/m, the laminated sheet using a new foamed resin layer having well-balanced properties, the amount of formaldehyde emitted from which is extremely small, as the adsorbing layer, the release sheet and the adsorbing layer having a proper release force.
