Abstract
Abstract A laminate in which a fabric backing is adhered to a composition containing a radial teleblock copolymer having blocks of poly(conjugated diene) and poly(monovinylaromatic) and sufficient surface dulling agent to provide a suede-like surface. A laminate as described having high air permeability and suede-like surface is used as material for uppers of shoes.
