Title:
LAMINATE AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JP3583222
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve the resistance to wear and interlaminar release strength and prevent the generation of recessed and projected patterns at the time of pulling of the like by a molten film forming a non-porous layer composed of a thermoplastic polyurethane containing a specified amount of at least one kind of condensate of a higher fatty acid and an aliphatic polyol and its metallic salt on the surface of a fibrous base layer.
SOLUTION: This laminate is provided with a porous layer 3 containing foams composed preferably of a thermoplastic elastomer and formed on the surface of a fabrous base layer 1 by a melt film method, and a non-porous layer 5 composed of a thermoplastic polyurethane composition 4 is formed on the porous layer, and recessed and projected patterns of mirror face patterns are formed on the surface of the non-porous layer 5. The thermoplastic polyurethane composition 4 to be used is formed by blending at least one kind of condensate of a higher fatty acid and an aliphatic polyol and its metallic salt of 0.5-5 pts.wt. to a thermoplastic polyurethane of 100 pts.wt.
