<p><P>PROBLEM TO BE SOLVED: To provide a semi-grained leather-like sheet which has good light resistance, is flexible, and has a high grade appearance and a high surface touch, and to provide a method for producing the same. <P>SOLUTION: The leather-like sheet obtained by forming cut pile portions comprising polyester fibers and grained portions comprising an elastic polymer consisting mainly of a polyurethane in a mixed state on the surface of a substrate comprising≤1.0 dtex polyester fibers, dyeing the treated fabric with a disperse dye, and reducing and washing the dyed fabric is characterized in that the elastic polymer satisfies the following expression (1): (A1)≤(A0)+0.5 [(A1) is K/S of the elastic polymer consisting mainly of a polyurethane, dyed with the disperse dye, and then reduced and washed; (A0) is K/S of the elastic polymer consisting mainly of the polyurethane, before dyed with the disperse dye], and that a hindered amine-based photostabilizer exists on the surface. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
