Abstract
A synthetic leather includes: a base cloth; on the base cloth, an adhesion layer, a skin layer, and a flame-retardant layer, in this order, in which the flame-retardant layer includes at least one selected from hydrotalcite or a hydrotalcite-like compound, and is a cured product of a composition that includes a binder and particles having an average particle diameter of from 10 nm to 2500 nm, and is a layer having a thickness of from 1 μm to 20 μm.
Claims12
A synthetic leather comprising:
- a base cloth;
- and
- on the base cloth, an adhesion layer, a skin layer, and a flame-retardant layer, in this order, wherein the flame-retardant layer comprises at least one selected from hydrotalcite or a hydrotalcite-like compound, is a cured product of a composition that comprises a binder and particles having an average particle diameter of from 10 nm to 2500 nm, and is a layer having a thickness of from 1 μm to 5 μm,
- wherein the hydrotalcite-like compound is a compound represented by General Formula (I) below,
- [(A1)2+1−x(A2)3+x(OH)2][(B1)n−x/n.mH2O] General Formula (I)
- wherein, in General Formula (I), (A1)2+ represents Ca2+, Mg2+, Fe2+, Co2+, Ni2+, Cu2+, or Zn2+, and (A2)3+ represents Al3+, Tifrom 3+ to 4+, Cr3+, Fe3+, Co3+, or (Mofrom 5+ to 6+),
- (B1)n− represents a sulfate derivative ion, a sulfonic acid derivative ion, or a phosphate derivative ion, and
- x represents a number of from 0.20 to 0.33, n represents a valence of an anion, and m represents an arbitrary number.
