Abstract
A synthetic resin skin material, including a base cloth and a vinyl chloride resin skin layer that is formed on the base cloth and that includes a vinyl chloride resin having a degree of polymerization of 1,600 to 3,000 and includes 3 parts by mass to 20 parts by mass of a silicon-acrylic copolymer with respect to 100 parts by mass of the vinyl chloride resin, and a manufacturing method thereof.
Claims13
A synthetic resin skin material, comprising:
- a base cloth;
- and
- a vinyl chloride resin skin layer that is formed at only one side of the base cloth, and that includes a vinyl chloride resin having a degree of polymerization of 1,600 to 3,000 and includes 7 parts by mass to 20 parts by mass of a silicon-acrylic copolymer with respect to 100 parts by mass of the vinyl chloride resin,
- wherein the vinyl chloride resin skin layer is not provided with a surface treatment layer at an opposite side from a base cloth side, or is provided with a surface treatment layer having a thickness of 1 to 3 μm at the opposite side from a base cloth side,
- the base cloth and the vinyl chloride resin skin layer are layered with at least one adhesive layer therebetween, and
