PROBLEM TO BE SOLVED: To obtain a pressure-sensitive adhesive sheet which has good color- developing properties and a sufficient flexibility, is excellent in following a curved surface, and is reduced in incineration load by forming a colored coating film on one side of a specific olefin resin substrate sheet and a pressure-sensitive adhesive layer on the other side. SOLUTION: A colored coating film comprising a pigment and at least one resin selected from among acrylic resins, urethane resins, polyester resins, and fluororesins is formed on one side of an olefin resin substrate sheet comprising 100 pts.wt. olefin resin and 3-90 pts.wt. vinylaromatic elastomer, and on the other side, a pressure-sensitive adhesive layer is formed. The substrate sheet may contain a pigment, which is preferably a white pigment, especially titanium oxide, in terms of hiding the color of an adherend and improving the chroma of the colored coating film. A preferable example of the vinylaromatic elastomer is a styrene-butadiene block copolymer.
