PROBLEM TO BE SOLVED: To obtain a sheet which is free from whitening caused by folding and has improved strengths and softness by sheeting a specificα-olefin-propylene compsn. SOLUTION: A sheet for decorative paper having a thickness of 0.020-1.00 mm is obtd. by sheeting anα-olefin-propylene resin compsn. which is prepd. by blending anα-olefin-propylene copolymer (A) having a propylene unit content of 90-99 wt.%, pref. 95-98 wt.%, with anα-olefin-propylene copolymer (B) having a propylene unit content of 40-85 wt.%, pref. 50-75 wt.%, an intrinsic viscosity [η]II (135 deg.C, in tetralin) of 1.5-3.0 dl/g and a ratio [η]II/[η]I of the intrinsic viscosity [η]I to that [η]II (measured under the same conditions) of copolymer A of 0.7-1.2 in such a manner that the product of the ratio of intrinsic viscosity and the wt. ratio (WI/WII) of copolymer A to copolymer B, [η]II/[η]I}×(WI/ WII), is 1.0-4.5.
