Abstract

A skin material ( 1 ) includes a cellular heat-insulating layer ( 3 ) and a coloring layer ( 4 ) which are sequentially stacked on a fibrous substrate ( 2 ) and has protrusions and recesses on a front face ( 6 ). The cellular heat-insulating layer ( 3 ) has a softening temperature of 110 to 250° C. A contact cool feeling (Qmax) of the front face ( 6 ) of the skin material ( 1 ) is 0.30 W/cm 2 or less both before and after a heat treatment for 2400 hours at 70° C.

First claim

1 . A skin material comprising a porous heat-insulating layer and a coloring layer which are sequentially stacked on a fibrous substrate, wherein the skin material has unevennesses on a front face, the porous heat-insulating layer has a softening temperature of 110° C. to 250° C., and a contact cool feeling (Qmax) of the front face of the skin material is 0.30 W/cm 2 or less both before and after a heat treatment for 2400 hours at 70° C.

2 . The skin material of claim 1 , wherein the porous heat-insulating layer is obtained by mixing a resin serving as a matrix with hollow fine particles, the matrix has a softening temperature of 110° C. to 250° C., and a glass transition point of −100° C. to 50° C., and a resin that forms outer shells of the hollow fine particles has a softening temperature of 110° C. to 250° C., and a glass transition point of 50° C. to 150° C.

3 . The skin material of claim 1 , wherein a contact area ratio on the front face of the skin material is 65% or less.

4 . The skin material of claim 1 , wherein a protective layer is stacked on the coloring layer.

5 . The skin material of claim 2 , wherein a contact area ratio on the front face of the skin material is 65% or less.

6 . The skin material of claim 2 , wherein a protective layer is stacked on the coloring layer.

7 . The skin material of claim 3 , wherein a protective layer is stacked on the coloring layer.

8 . The skin material of claim 5 , wherein a protective layer is stacked on the coloring layer.
