<p><P>PROBLEM TO BE SOLVED: To obtain sufficient bonding strength with a printed layer. <P>SOLUTION: This olefin system floor material is constituted by laminating the printed layer 4 containing synthetic resin on a lower face of a surface resin layer 2 containing olefin resin and laminating and integrating a basic material layer 3 containing olefin resin through an adhesive layer 5 on a lower face of the printed layer 4. The adhesive layer 5 contains carboxylic acid denatured propylene-1-butene copolymer resin and carboxylic acid denatured propylene-ethylene-1-butene copolymer resin, and a mass ratio of carboxylic acid denatured propylene-1-butene copolymer resin to carboxylic acid denatured propylene-ethylene-1-butene copolymer resin is in a scope of 55/45 to 95/5. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
