PURPOSE:To obtain the subject curtain having durable flame-proofing effect by using a flame-retardant fiber substrate as the surface layer of the curtain, laminating a skin layer containing a specific modified material to the back face of the substrate with an adhesive layer having a specific component containing a flame-retardant and coloring the adhesive layer or the skin layer in dark color. CONSTITUTION:A flame-retardant fiber substrate or a fiber substrate subjected to flame-retarding treatment is used as the surface layer of a curtain. A polyurethane skin layer containing a flame retardant and a modified polyisocyanate is laminated to the back face of the substrate using a two-pack type polyurethane adhesive containing a flame retardant. One of the adhesive layer and the skin layer is colored in dark color to obtain the objective flame-retardant light-shielding curtain having excellent hydrolysis resistance and light resistance. The polymer diol constituting the urethane is preferably a polyester diol having a softening point of >=170 deg.C to attain heat-resistance. The flame retardant is e.g. a bromine-containing urethane produced by reacting an organic polyisocyanate with a bromine-containing compound or a phosphorus-containing and bromine-containing compound having one or more active hydrogen atoms.
