Abstract
A method of producing a polyurethane foam sheet, and a laminated sheet that uses such a foam sheet, that can be applied to artificial leather, synthetic leather, and cushioning materials used in all manner of applications. A polyurethane foam sheet is produced by applying a liquid mixture, obtained by mixing together a heated and melted hot melt urethane prepolymer (A) containing isocyanate groups at molecular terminals, and a compound (B) containing at least 2 active hydrogen atom-containing groups, onto a substrate in a sheet-like manner, and then water foaming the liquid mixture by bringing the sheet-like liquid mixture into contact with water vapor or moisture (water). A laminated sheet is produced by bonding a third substrate to the polyurethane foam sheet.
