ABSTRACT:
The present invention relates to a laminated material characterized in that, in the laminated material wherein a polyolefinic thermoplastic elastomer(B) containing an oily softening agent is laminated on the surface layer comprising a polyolefinic thermoplastic elastomer(A) containing an oily softening agent, the ratio(a) of the oily softening agent to the amorphous component(or to the total of the amorphous component and polyethylene if polyethylene is incorporated) in the thermoplastic elastomer(A) and the ratio(b) of the oily softening agent to the amorphous component(or to the total of the amorphous component and polyethylene if polyethylene is incorpirated) in the thermoplastic elastomer(B) satisfy the following requisites;ratio(a)≧ratio(b),ratio(a)=5 to 200 wt. %, andratio(b)=5 to 200 wt. %,and relates to a glass-run channel, and a roof molding, side molding and window molding for automobiles comprising the laminated material.
