PURPOSE: A synthetic resin based bottom tile is provided to enhance the print contrast of a printing layer and to have the good weatherability, abrasion resistance and contamination resistance by using an olefinic ionomer resin and not using a UV curable paint. CONSTITUTION: The synthetic resin based bottom tile having a lamination structure comprises an olefinic ionomer resin layer as a surface resin layer. The olefinic ionomer resin is a copolymer of an olefin with a carboxylic acid group neutralized partially by a metal ion and salt and an alpha, beta-unsaturated carboxylic acid. The bottom tile comprises, from the top, an ionomer resin layer(1), an adhesive resin layer(2), a vinylchloride inter-layer(3), a substrate layer(5) and a back side layer(6), in order.
