Abstract
A cholesteric resin layered body including a substrate, an intermediate layer, and a cholesteric resin layer in this order, wherein a difference in a reflection band center wavelength of the cholesteric resin layer before and after the layered body is heated at 130° C. for 8 hours is 50 nm or less, method for producing the same, as well as a reflective material, a display medium and a decorating material including the same.
Claims15
A cholesteric resin layered body comprising a substrate, an intermediate layer, and a cholesteric resin layer in this order, wherein
- the intermediate layer is a layer of a cured product of a material containing a modified polyvinyl alcohol compound and a curing agent,
- a ratio of the curing agent relative to 100 parts by weight of the modified polyvinyl alcohol compound is 5 parts by weight or more and 20 parts by weight or less, and
- a difference in a reflection band center wavelength of the cholesteric resin layer before and after the layered body is heated at 130° C. for 8 hours is 50 nm or less.
